Since life formed on our planet, it has developed under a predictable rhythmic environment. Thus, every life form has evolved to ensure the temporal coordination with its resonating environment, a task performed by the circadian system.

The circadian system of mammals is composed of a hierarchically organized network of structures responsible for the generation and synchronization of circadian rhythms to the environment. It includes a central pacemaker, located in the suprachiasmatic nucleus (SCN) of the hypothalamus, and several peripheral clocks.

The SCN acts as a music director and generates oscillations of approximately 24 hours (circadian) orchestring the endogenous rhythmicity in physiology, behaviour and metabolism. It diffuses its temporal signal to the organism thanks to melatonin, a hormone produced by the pineal gland known as the chemical darkness, which peaks at night and shows low levels during day. Therefore, circadian changes in its daily production are used both, as a daily clock informing the organism that it is night-time and as a calendar since the duration of night-time elevation changes seasonally…whenever no light is received by the organism during the night.

A conductor needs a score, and thus the SNC needs to be reset every day by light in order to avoid free-run. The light reaches the master clock through a nonvisual pathway consisting of the melanopsin ganglionar cells (a specialised cells in the retina which are particularly sensitive to light of 460-480 nm, that it is to blue light) and the retinohypothalamic tract and suppress melatonin secretion during the day or, if present, also during the night. However, it has been only recently that night has been illuminated in order to satisfy the 24h/365 days continuous operations, and so an increasing number of people is working night shifts or engaged in nocturnal leisure activities, or just suffer from light intrusion in their homes. All of them imply exposure at light during the night.

A growing and increasingly convincing body of scientific evidence suggests that excessive exposure of bright light at night (LAN) generates circadian disruption or chronodisruption, that it is, impairments in the healthy internal temporal order. Evidences point to melatonin inhibition as the principal responsible, and blue light is the most effective in this suppression while longer time exposures are required with warmer lights.

Epidemiological studies show that chonodisruption is associated with an increased incidence of metabolic syndrome, cardiovascular diseases, cognitive and affective impairments, premature aging and some cancers such as breast, prostate and colorectal and the worsening of pre-existing pathologies, so light is not harmless anymore.

In modern societies, with the morbidity and mortality demonstrated in experimental animals associated with chronodisruption (CD), light hygiene is a major health concern. To date, we know some of the health consequences of CD; however, only a few attempts have been made to prevent circadian disruption induced by inappropriate lighting. Blue light should be avoided during the night in order to preserve our circadian physiology.

Moon days, energy saving lessons

Susana Malón and María Álvarez. Lumínica Ambiental. Soc. Astronómica de Álava

cerrar Street lighting is an issue recurrently addressed for several hundred years. Analysing several historical documents, we get an understanding of the different solutions put into practice, depending on the technology available and applied in each period. We can also see the evolution of the concept of the public outdoor lighting service and the consideration of darkness and the natural light of the night. These historic documents show respect and care for the environment and nature as well as social awareness of the value of public services missing nowadays. Just looking back at what our great-grandparents did and applying current technology with common sense we can see the essential principles currently defended by dark sky protection groups.

LED Street Lighting for Dark Sky protected areas

Ramón Llorens. SACOPA - IGNIA LIGHT

cerrar Artificial lighting for areas of Astronomical interest should meet the very strict requirements that until now could only meet Sodium vapor lamps. It happens the same with Ecology Protected areas in order to prevent that illumination could affect to the flora and fauna. The smart use of Amber and PC-amber LEDs in these areas opens up unthinkable expectations of light pollution control. The presentation shows the inconvenience of lighting these areas with white LEDs due to its high emission pick in 440nm, and how can it be solved using PC-Amber or Amber LEDs. This new technology used by SACOPA - IGNIALIGHT has been tested in terms of affecting to nocturnal wildlife, humans, photobiological safety norms and light pollution. Some success cases are shown in the end of the presentation.

State of the art of the use of LED technology in the protected area of the Canary Islands

F. Javier Díaz Castro. OTPC - IAC

cerrar In this communication we present the solutions we are providing to the use of LEDs in areas protected by the Sky Law of the Canaries. We present the spectra of LEDs currently replacing conventional discharge lamps specified in the Law and its advantages and weaknesses.

Light Decontamination of urban areas. Criteria to be used in the present economic situation

Josep M. Ollé. Ajuntament de Reus y Universitat Rovira i Virgili

cerrar We present examples of decontamination light of urban areas, both residential as high for commercial use, lighting explaining the criteria that were used and how technology was used, with photographs before and after the performance. Based on the experience gained and given the current economic situation will propose more stringent limitations las advocate that the current regulations in Spain.

Ground-based imaging spectrometry for light pollution measurement

Salvador Bará. Universidad de Santiago de Compostela

cerrar Airborne imaging spectrometers have been used in light pollution monitoring to measure the upward light emissions to the atmosphere and to detect and classify pollutant sources. In combination with suitable models of atmospheric propagation and scattering these data allow one to make quantitative estimates of the night sky radiance, whose increase over the natural levels is one of the most direct manifestations of the light pollution problem. However, several detrimental effects of light pollution at ground sites are determined not only (nor mainly) by the sky radiance but by the radiance directly received from the artificial sources through the line-of-sight and reflected paths. In this communication we report on the use of wide-field ground based imaging spectrometry to measure the spectral radiance of the nightscape, including both natural and artificial sources, and to estimate the spectral irradiance at the observer location. With these inputs several relevant light pollution magnitudes (e.g, the circadian light illuminance) can be computed and the main sources contributing to them can be located and identified.

Measuring Light Pollution in Montsec: a protected area

Salvador Ribas. Parc Astronomic Montsec

cerrar Montsec Mountains are a special protected place in Catalonia (NE of Iberian Peninsula). Since mid-90’s, this area was selected for amateur astronomers to install their astronomical observatories. In 2002 the Government of Catalonia started the project Parc Astronòmic Montsec with the aim to have two astronomical installations: one for research and the other for outreach and education. Dark skies are probably the most valuable thing in Montsec and for this reason this area is specially protected by Catalonian Laws. In 2012, Parc Astronomic Montsec and the official Catalan Service against Light Pollution have developed a measurement plan using different kind of data. The results of this study showed Montsec is one of the best places in Southern Europe with typical sky brightness better than 21.0 and in some places between 21.5 and 22.0.

Two years Night Sky Brightness measurements In The Netherlands

Marty Haaima. RIVM

cerrar Night Sky Brightness in The Netherlands is being monitored within the MHN monitoring network since 2011. This network measures night sky brightness continuously on nine locations. The measurement sites are located on industrial, urban, rural and remote locations. The night sky brighntess is measured using the Sky Quality Meters (SQM-LEs). The SQMs have been intercompared prior to installation and one year later in the international CLIC campaign. One of the goals of the network is to determine actual levels and variability of the night sky brightness in The Netherlands. An analysis using the two year data set is presented, key features of the results are shown and the usability of the data beyond the primary goals is discussed.

Start of Monitoring the Colors of the Night

H. Spoelstra. Lumineux Consult

cerrar The introduction of LED lighting in the outdoor environment may increase the night time blue color level and light pollution caused by the stronger Rayleigh light scattering. Blue light may also have an impact on circadian rhythm of humans due to the breakdown of melatonin. At present no long term data sets of color levels of the night sky are available. In order to facilitate the monitoring the levels and variations in the night sky colors a low cost multi filter instrument is presented. Design considerations are presented as well as the choice of suitable filters, which showed to be critical especially in the green band from 500 to 600 nm. In this spectral band available astronomical filters showed to exclude some or all of the low and high pressure sodium lines from lamps which are important in light pollution research. For this band filters from the optical industry were chosen. Correction factors were calculated to correct for the detector response and filter transmissions. The first results at a suburban monitoring station showed that the light levels between 500 and 600 nm are dominant during clear and cloudy skies. The relative contribution of blue light increases when the night sky becomes clear (without moon). The impact under moon lit skies showed to be more complex and is still under study.

13:10 – 13:30 Sesión de pósteres

Practice of public lighting in proposed German Star Parks

Andreas Hãnel. Dark Sky Germany, Museum am Schoelerberg

cerrar We made a lighting inventory of about 10000 luminaires for the proposed star parks Westhavelland and Rhoen in Germany. From these data we derive characteristic numbers for the energy use and light emission. We detect a significant difference between the two parks. And we propose a limiting value for street lighting for discussion.

Public awareness versus administrative sloppiness: light pollution in Valencia

Angel Morales. Dep. de Química Analítica, Univ. Valencia; Coordinadora en Defensa de los Bosques del Turia

Enric Marco. Dep. d’Astronomia i Astrofísica, Univ. Valencia; Cel Fosc Valencian Coordinator

cerrar Solving the problem of light pollution lies mainly in government (municipalities, state, regional and provincial governments). But these are reluctant to take the plunge or even refuse to lessen their impact. Only from social groups, especially environmental organisations, you can force change. We present two examples (Valencia airport and IVADIS residence in Manises, both located nearby the Parc Natural del Turia) in which the administrative authorities show sloppiness and negligence to solve the problem. We detail the initiatives undertaken by the Coordinadora in defensa de los bosques del Turia in order to reduce light pollution in these two cases.

Radiofrequency interference. Status and challenges

F. Colomer, J.A. López Pérez and J.A. López Fernández. Instituto Geográfico Nacional (IGN)

cerrar Radio astronomy observatories around the world face the challenge of achieving high sensitivity observations of the Universe while their sites are getting heavily affected by radio frequency interferences (RFI). Protection is difficult, and its extent depends on national laws. We describe the status and monitoring tools used in the IGN Yebes Observatory (Spain).

Public awareness through the observation of the night sky

X. Dositeo Veiga. Albergue Os Biocos - Altega S. L.

cerrar Light pollution has become an undesirable effect of outdoor lighting. A necessary step in this debate is public awareness. References to the waste of energy or to environmental issues tend to work well with any audience. However, these arguments can be used to address many other problems as well. We can get more visibility and draw the attention of the public appealing to their feelings, to their heart. This is possible if we show a clear evidence of what we are missing out due to light pollution. A simple tool can help us to achieve this goal: the observation of the night sky. In our contemporary societies, predominantly urban, people have lost the habit of observing the dark night sky, finding constellations, discovering the North Star, or just enjoying the Milky Way with a naked eye. Education and outreach programs such as astronomical observations, both in an urban setting and in a privilege location such as “Os Biocos” Hostel (Ourense), are the best solution to increase public awareness about light pollution. Through these scientific based activities, the general public understands the magnitude of the problem and realize what they are missing out when they are not exposed to the beauty of a night sky. Key words: public awareness, popular science, night sky observation.

Skies over Sierra Morena, protecting one of the darkest places in Europe

José Jiménez. Dark Sky Advisors, As. Astro. Hubble, Iberus Medio Ambiente S.L., ADIT-Sierra Morena

cerrar Sierra Morena is a huge range of mountains and valleys that extends more than 370 km in southern Spain and that includes five natural parks and one biosphere reserve. The quality of the night sky is simply amazing, reaching the stunning digit of 21.7 mag/seg arc² in many places. Nowadays, some efforts are taking place to protect this resource, this project is a good example about how to involve local administration and the private sector in this task.

Dark Sky Conservation in Sierra Sur Range. The astronomy as a tool of social revitalization and environnmental conservation

José Jiménez. Dark Sky Advisors, As. Astro. Hubble, Iberus Medio Ambiente S.L., ADIT-Sierra Morena

cerrar Sierra Sur is a complex territory formed by high mountains that reach almost 2000 meters over sea level, impressive cliffs and rock walls are common in this region. The low density of population gives the chance of preserving a really dark sky at night, so during 2013 and 2014 a project to set in value this resource is taking place there. If you like astronomy in Spain, you probably has ear about Astromartos or the Observatory of La Pedriza, in fact local administration is doing a huge effort to remark this places as a destiny for amateur astronomers looking for a good place to observe. An important invest is being developed to adapt some observation places and also to certificate the region as Starlight Reserve in 2014.

Night Sky Brightness and Light Pollution in Comunidad de Madrid

J. Zamorano, A. Sánchez de Miguel, J. Gómez-Castaño, F. Ocaña, J. Gallego, B. Pila, M. Nievas, C. Tapia, A. Fernández & S. Pascual. Universidad Complutense de Madrid

cerrar Preliminary results of a study of the night sky background brightness around the city of Madrid using Sky Quality Meter (SQM) photometers are presented. Data retrieval methodology includes an automatic procedure to measure from a moving vehicle which allows to speed up the data gathering. The night sky brightness, an astronomical quality parameter that accounts for luminous flux from the sky, is closely related with the light pollution. The map with the spatial distribution of the night sky brightness around Madrid has been compared to the light pollution as measured with calibrated satellite imagery and nocturnal images taken by astronauts aboard the International Space Station (ISS).

NIXNOX project: Sites in Spain where citizens can enjoy dark starry skies

J. Zamorano, A. Sánchez de Miguel, E. Alfaro, D. Martínez-Delgado, F. Ocaña, J. Gómez Castaño & M. Nievas.. Universidad Complutense de Madrid

cerrar The NIXNOX project, sponsored by the Spanish Astronomical Society, is a Pro-Am collaboration with the aim of finding sites with dark skies. All sky data of the night sky brightness is being obtained by amateur astronomers with Sky Quality Meter (SQM) photometers. We are not looking for remote locations because the places should be easily accessible by people with children. Our goal is to motivate citizens to observe the night sky. NIXNOX will provide information to answer the question: where can I go to observe the stars with my family?

Control and inspection of light pollution by European Environmental Police

Joan Manuel Bullón Lahuerta. Asoc. Prof. Agentes MA. de la C. Valenciana

cerrar The European Environmental Police is responsible for ensuring a healthy Environment in the European Union. Most nations in the world have got this service trought their respective civil servants, known as Rangers. In Spain, each region is endowed with its teams dedicated to this problems with different names. In the Valencian Comunity environmental agents, as also for other environmental bodies in the other spanish regions, come from the State Forest Rangers of the extinct "Instituto para la Conservación de la Naturaleza" (ICONA). The idea of this paper is to propose that the staff officer in charge of caring for forest and environment should be prepared and able to measure light pollution, urgin enforce environmental regulations on the protection of the dark sky and also trying to decontaminate as much as possible from polluting sources, as is done in other types o pollution, such as spills, noise etc.. This is the reason why we should require to Spanish regional governments and also to the European countries to incorporate into their environmental departments the fight against light pollution, work that would be generously developed by officials belonging to the European Environmental Police in collaboration with the corresponding environmental public prosecutor's offices.

Sky Darkness conservation efforts in Andalucía

José Jiménez. Asociación Astronómica Hubble

cerrar Andalucia is located in the south of the Iberian Peninsula. Its landscape context is formed by a huge mix of different habitat that includes from high mountains at the east and south to big plains of open forest in the north. The population is mostly centered in the down lands, where it's possible to find big cities like Sevilla or Malaga. This fact make possible to find many regions where the density of people is almost nule, and that's why in this region a very well preserved dark sky is still present nowadays. Two of these region are in this moment under a complete program of conservation and certification under the figure of Starlight Reserve. Sierra Sur Range in the province of Jaén and Sierra Morena, that involves four provinces, Huelva, Sevilla, Cordoba and Jaen. The entity called Dark Sky Advisors (formed by the consortium of Hubble Astronomy Association and Iberus Medio Ambiente) is running both projects. We have accumulated a lot of experience taking measurements of the night sky background brightness and having many meetings with the local authorities. With the process of make of the sky a valuable resource, we're achieving our goal of preserving the darkness in our skies. In this short conference we would like to share our experiences with anyone interesting in starting simillar projects.

18 years around the Catalonian law

Pere Horts. Cel Fosc, Asociación contra la Contaminación Lumínica

cerrar In the mid 90s a group of friends in Catalonia, united by our love for astronomy began to take the first steps to try to solve a problem that was stealing the night, light pollution. The objective was clear: to get the lighting of the streets be more respectful and intelligent. To do this we decided to promote a regional law committed to protect the night. We have this law since 2001, but the main goal has not been reached yet. However, as Konstantinos Kavafis said, what matters is not reaching a Ítaka but the road leading to it. On this way we met a lot of wonderful people like Dr. Ramon San Martin, whose memory will always be with us, we founded Cel Fosc as a national association and got together many of those who are outraged by having to bear and pay so poor lighting. Today we can say that all this was worth it.

The renovation of the street lighting systems in Navarre

Esperanza Aristu. Gobierno de Navarra

cerrar In this presentation we will proceed to explain the actions on public lighting implemented by the Government of Navarre in the last years. These actions take place at the legislative level, in the sectoral plans and in the calls for aids for the renewal of public lighting. The Regional Law 10/2005, regulating the lighting system for the protection of the night and Foral Decree that develops it, along with the national RD1890/2008 are the legislative framework in which we have worked in recent years.

The establishment of IDA Tokyo and plans for raising public awareness about light pollution

Nobuaki Ochi. Toyo University

cerrar IDA Tokyo was established in January 2013. Scientific researchers, lighting designers and amateur astronomers collaborate to raise public awareness about light pollution. We present plans of educational actions which will be done around Tokyo, one of the brightest areas in the world.

Zernike analysis of all-sky night brightness maps

Salvador Bará. Universidade de Santiago de Compostela

cerrar All-sky night brightness maps -calibrated images of the night sky with hemispherical field-of-view taken at standard photometric bands- provide useful data to assess the light pollution levels at any ground site. We show that these all-sky images can be efficiently described and analyzed in terms of the Zernike circle polynomials. Besides compressing the relevant image information into a small-sized data vector, providing analytic expressions for the spatial distribution of sky brightness, and alleviating the effects of noise, the finite Zernike expansions allow to discriminate the spatially smooth radiance distribution due to atmospheric scattering from that associated to pointlike natural or artificial sources. The Zernike coefficients also allow to quantify in a straightforward way the average sky brightness, its variation across the field of view and its degree of asymmetry, providing an easy framework to analyze the evolution of these magnitudes throughout the night.

Preliminary Data from the Loss of the Night Android App

Christopher Kyba. Freie Universitãt Berlin

cerrar The last four years have seen a major increase in the amount of information available on the levels of external light at night. The radiance of the sky is now continuously monitored at many tens of locations worldwide, the new VIIRS instrument on the Suomi NPP satellite has greatly enhanced spatial and radiance resolution over DMSP, and imagery from the ISS and nighttime flights have allowed high resolution analyses. It is likely that many or all of these devices will be replaced within the next decades by advanced instruments with different sensitivities, and this is problematic from the perspective of developing time series. The slow evolution of the human eye makes it an ideal instrument for developing time series over a period of decades. We have developed a smartphone app that allows citizen scientists to quantify the naked eye limiting magnitude (i.e. the faintest visible star). This parameter is very highly correlated with skyglow, is easy to understand, and should be very stable with time. The ubiquity of smartphones means that skyglow luminance data could be acquired worldwide, and in particular in areas undergoing rapid development. We present the methodology of the app, and preliminary results based on data taken in spring and summer, 2013. In addition to providing valuable data, the app has educational and cultural value. Its use requires no prior observational experience, and users can very quickly become familiar with the names of the brightest stars and some constellations, bringing urban dwellers into closer contact with the cosmos. Finally, the app also provides an instrument for students to assess skyglow luminance without purchasing a lightmeter. Students can thus conduct their own projects, while at the same time participating in a worldwide citizen science project.

Temporal evolution of light pollution sources using ISS images and others: Madrid

Alejandro Sánchez de Miguel. Universidad Complutense de Madrid

cerrar The study and control of light pollution presents several difficulties. The first of them is that the sky background brightness depends on many factors, not only on the artificial sources of light. To study the variation of these sources, we prefer to study them directly. The images of the International Space Station (ISS), provide us a wide range of resolutions from several kilometers to a few meters. In these images is relatively easy to identify sources of light. However its calibration is rather complicated. Then, the images must be related to variations in sky background brightness. In addition to the images provided by the ISS crews, other direct detection methods such as ground imaging and the data collected by luxometers aboard balloons and airplanes are used by our team. We will show an example for the case of Madrid.

Protecting Dark Skies – An Ongoing Program of Diligence and Education in Borrego Springs, California

James Hoban Rickard. Borrego Springs Dark Sky Coalition

cerrar Obtaining the Dark Sky Community designation from IDA was just the beginning. There is an ongoing program to maintain and improve local lighting. DILIGENCE means identifying new violations of dark sky criteria by annual surveys of lighting fixtures and informing the owners of non-conformity. This is coupled with offers of advice about the commercial availability of dark sky friendly fixtures. EDUCATION means generating articles for the local media, providing a postal brochure for every resident, information for visitors at local hotels, and a new program for business recognition. We will show the kind of certificates to be awarded to businesses to keep dark skies in the public eye. In this way everyone in the community can participate in protecting our night sky.

Monitoring the Valencian sky. Polluted natural areas and dark places to be preserved

Enric Marco. Universidad de Valencia, Cel Fosc

cerrar It is well known that Valencia is usually considered one of the more light polluted city in Europe. Astronomers are not the only one affected by its pollution. It has been well reported that excessive number of artificial light points and incorrect installation of luminaires exert strong influences on nocturnal wildlife. Three Valencian natural parks, located nearby to the Valencian metropolitan area, are strongly polluted due its unshielded public lighting system. The introduction of LED technology into the street lighting in many Valencian towns, supported and financed by Valencian public administrations, is the reason of the migration from the now widely used high-pressure sodium lamps to white lamps with a strong emission peak in the blue band. This action, promoted as an enhancement of the energy efficiency, is going to increase very quickly light pollution and even to exert greater pressure on natural ecosystems and human health. This work presents measurements of night sky background obtained in Valencian natural parks and some areas of interest. It also detects and characterizes pollutant hot spots and the first effects of the cold LED lighting systems. Although very polluted areas are found near Valencia and the main Valencian cities, it is worth noting that there are still some natural areas, such as the Natural Park Chera-Sot de Chera, and the regions of la Serranía, el Rincón de Ademuz and els Ports with excellent dark sky. These must be protected from future environmental assaults such as white LED lighting or flashing white light projectors for wind turbines.

Protecting Dark Sky Areas: Global Issue - Local Interests

Josiane Meier. Tec. Univ. Berlin, Dp. Urban and Reg. Planning

cerrar As a consequence of growing light pollution, areas with naturally dark nights have become scarce in many countries and are increasingly considered to be worthy of protection. The currently most prominent way of doing so is the designation of dark sky areas. A growing number of such areas has been designated in recent years. In order to be certified as a dark sky area by organisations such as the IDA or RASC, public policies must be adopted and political and public support are necessary. This presentation will first provide an overview of designated areas and designation options. Using three case studies, it will highlight the broad range of actors and interests that play into the designation of dark sky areas.

Light Pollution in the Nature Park TerraVita

Andreas Hãnel. Dark Sky Germany

cerrar During the last 4 years we have studied the night sky brightness in the nature (and geo) park Terra.Vita around Osnabrück. We tried to: - study the sky quality at the observatory - find the darkest places in the region - study the influence of different light sources (like parking areas, industrial areas, cities) - developped lighting guidelines for artificial lighting to reduce light pollution (also within the projects of star parks in Westhavelland and Rhoen). This work has been partially funded by the Bingo! environmental protection foundation of Niedersachsen.
