The New England Light Pollution Advisory Group The New England Light Pollution Advisory Group (NELPAG) A big role of NELPAG has been providing information through this Website since early 1995, with hundreds of accesses to this page being logged every week for the past couple of years (as of August 1997, we counted more than 47,000 accesses to this page; our best week so far was the one ending 1997 May 4, when 766 accesses to this page were recorded in that week alone). [As of August 1999, we are still getting 400-600 accesses per week, with over 100,000 estimated accesses to these NELPAG web pages since 1995.] We have found that there is a great public demand for information on outdoor-lighting issues, and that there has been unfortunately a great dearth of sources that the interested individual can seek out. It should not be surprising, then, that we have received high praise from many people around the world for the information provided here. Imagine children growing up without being allowed to see trees or birds (or any other aspect of nature): now, how is this any different from preventing our children from seeing the stars?! But by our thoughtless erection of outdoor lights everywhere - without consideration of glare and light trespass, without consideration of safety, without consideration of the right to privacy, and without consideration of the energy waste and the waste of taxpayer dollars - we are making it so that a very small percentage of children are able to grow up in the world today with the ability to see and ponder the wonders of our beautiful starry night sky. Indeed, after a full century now of outdoor electrical lighting, one must wonder what a lot of the lighting manufacturers and installers were

3. Light Pollution, The Neglected Problem light pollution The Neglected. Problem http://www.monmouth.com/~ksears/litepol1.htm

Light Pollution: The Neglected Problem By John Batinsey Member, Eatontown, New Jersey, Environmental Commission A version of this article appeared with the same title in the Winter 1994 issue of ANJEC Report. Do you sometimes find yourself squinting at night just to see the roadway? Do you ever wonder why that is? Surely all the glare and obtrusive light causing this loss of visibility must be necessary-part of civilization. After researching the causes of light pollution, the Eatontown Environmental Commission realized that we can have effective outdoor lighting without these problems. As a result, Eatontown adopted a comprehensive outdoor lighting ordinance whose goals are to reduce unnecessary glare, thereby improving night-time visibility for safety and security. The ordinance will also help reduce unnecessary sky glow. Most of these improvements will even save energy, as well as reduce cost. ENERGY SAVINGS Much of the outdoor lighting that we see at night wastes energy in the following different ways: by excessive illumination, by unshielded or misaligned light fixtures, and by inefficient lamp sources. EXCESSIVE ILLUMINATION.

See if your neighbors plan to use the coupon, if not, ask if you can have it. We can stockpile some up at the NJAA for folks who are interested. I know many non-amateur astronomers are saying "Huh? What's that?" The best way to describe Light Pollution is to give you a couple of examples. While driving on any highway or road at night, do you have to squint from the glare as you approach street lights? Does the street light in front of your house shine into your windows to the point where you need the blinds down to sleep at night? Does your neighbors light on his back porch light up YOUR back yard ? When you look up at the sky on a cloudy night, can you see the clouds? Well if you've answered yes to any of these questions you've experienced light pollution.

The Astronomical Society of Greater Hartford is a club member of the International Dark-Sky Association The members of the Light Pollution Education Committee work hard to raise awareness of the Society members and the general public to inform them about the effects that obtrusive outdoor lighting have on society. Light Pollution affects astronomers more profoundly in one way because it greatly diminishes, if not completely removes the view of deep sky objects in the cosmos, but the Light Pollution affects everyone! Join! What is Light Pollution? How could light ever pollute something? It disappears as soon as the lamp is turned off and no sticky toxic residue is left in its wake. This cannot be a form of pollution, can it? The answer is yes, light can actually pollute the outdoor environment and wash away the view of stars in the sky. As awareness raises around the world, this term is heard in more and more places. It is a curable problem and can be prevented through the application of well designed and applied outdoor lighting. Light Pollution occurs in the three following forms: It causes an atmospheric phenomenon known as skyglow. Have you ever noticed the clouds overhead glowing an eerie pink, white, or orange color before? This wasted light is known as skyglow. It happens because of poorly designed and improperly aimed light fixtures called luminaires. Luminaires that do not offer adequate shielding usually spill wasted light into the sky and across property lines where it does not benefit anyone. When light spills into the sky, it reflects off of tiny airborne dust and moisture particles. This happens even on very clear evenings, too. The skyglow phenomenon directly affects the scientific research of amateur and professional astronomers. It also affects everyone else who simply enjoys a dark night sky abundant with stars overhead. Skyglow is a curable condition, and we can still have adequate and safe illumination in the outdoor environment.

7. Light Pollution And Narrow-Band Filters Article by Dave Knisely of the Prairie Astronomy Club. http://www.prairieastronomyclub.org/filters.htm

SOME AVAILABLE LIGHT POLLUTION AND NARROW-BAND FILTERS by Dave Knisely There are a number of different filters available on the market today for improving the views of various Deep-Sky objects, with most coming in one of three classes: 1. Broad-Band "light pollution" filters, 2. Narrow-Band "Nebula" filters, and 3: Line filters. The broad-band "Light Pollution Reduction" (LPR) filters are designed to improve the visibility of a variety of Deep-Sky objects by blocking out the common Mercury vapor, Sodium, and some other emission lines from man-made or natural sources which contribute to light pollution, while letting through a broad range of other more useful wavelengths. Since the eye is mainly a "contrast detector", this selective screening out of some of the background skyglow increases the contrast and helps Deep-sky objects stand out more noticably. While these filters do not eliminate the effects of light pollution or make the objects brighter, in many cases, these filters can improve the visibility of some deep-sky objects to at least some degree. In addition, larger versions of these broadband filters which fit over camera lenses can be somewhat useful for photography of wide star fields when some skyglow is present. For recommendations, I like the Lumicon UHC or Orion Ultrablock (whichever is less expensive at the time), and the Lumicon OIII, but remember to use them with an eye that is properly dark adapted and employ averted vision. Filters won't make the objects brighter, but in many cases, they will make many of them a lot easier to see. Have fun!

SEARCH: Spacewatch: Backyard Astronomy advertisement Czech Republic Enacts World's First National Light Pollution Law By SPACE.com Staff posted: 04:50 pm ET 18 March 2002 In February, the Czech Republic became the first country to enact national legislation aimed at eliminating light pollution. Known as the "Protection of the Atmosphere Act," the bill passed both houses of parliament (Chamber of Deputies and Senate) and was signed into law by President Vaclav Havel on February 27, 2002. It takes effect June 1, 2002, and addresses light and other kinds of air pollution. This news was announced Monday at the annual conference of the International Dark-Sky Association (IDA) in Tucson, Arizona. The group, which has grown to more than 4,000 members in 69 countries across the globe since 1988, works to combat light pollution to preserve and protect the nocturnal environment. The IDA, a diverse group of astronomers, lighting designers and manufacturers, environmentalists, ecologists, government officials even ophthalmologists addresses the issue of light pollution with information sheets, videos, newsletters and media-savvy lobbying.

Scoping Scopes: How to Buy Your Own Eye to the Sky Dr. David L. Crawford, astronomer and volunteer executive director of the IDA, views the Czech Republic legislation as "a great leap forward" in combating light pollution around the globe. "We applaud the Czechs and are committed to helping other governments enact similar legislation," Crawford said. "Fully shielded light fixtures not only help preserve the beauty of the starry sky, but they also illuminate more efficiently and allow people to see better at night."

The Antilightpollution Section. History The Astronomical SocietysAnti-lightpollution Section (AS-ALS) was established in 1992 http://as.dsri.dk/sect/light.html

The Anti-lightpollution Section History: The Astronomical Societys Anti-lightpollution Section (AS-ALS) was established in 1992, but lightpollution has been discussed by professional and amateur astronomers at least since the beginning of the 1980'ties, primarily in the USA. Goal: The section contributes to the fight against lightpollution in Denmark with the purpose to secure everyones possibility to enjoy and study the night sky. The objectives of the section are: To gather members interested in lightpollution. To gather and distribute knowledge about lightpollution, its causes, extent and possible countermeasures. To initialize and participate in a debate about lightpollution. Offer advice to the solution of problems caused by lightpollution. Activities: The section has published a number of papers on the subject of lightpollution, which all members joining the section will recieve and the section also publishes a newsletter which is sent to all members of the section. The members furthermore recieve invitations to talks arranged by the section alone or in coorporation with others and the section also produces information-sheets, booklets, folders, poster-exhibitions and T-shirts which can be ordered/bought/rented or lended. The section also compiles a library, a slide collection and a database containing addresses of companies, organisations and authorities relevant for the work of the section. Level of Activity: From the work of the section in 1993 the following activities can be mentioned: One member has distributed a folder about lightpollution at a public observatory. Another member has translated and adapted information-sheets from English to Danish. A third member has arranged a meeting, where an invited speaker gave a talk including a slide-show about lightpollution. A fourth member took advantage of the expected meteor-shower in august and obtained some media-coverage with a suggestion about turning of the street-lights in Copenhagen. A member has been in contact with representatives for an electricity company and with mayors and technical staff from some communities. A member has participated in a nordic outdoor lighting cogress with a poster-exhibition and distribution of different folders. Generally the level of activity is 100% dependant on the effort made by the individual members.

LIGHT POLLUTION INTERNET FORUM Our forum aim is to connect "Light Pollution" Internet friends world-wide, to improve the quality of lighting around the globe, and to discover innovative methods for employing Internet technology in the practice of protecting the environment. This Internet based forum grew out of the realization that we were many who cared about "Light Pollution" but sometimes we don't know what the other do or what they have already done. Inspiration for creating this Forum on Light Pollution, also came from watching the "Open Source" aspect of the computer world. This is an example where sharing information and knowledge has been an integral part of developing new ideas and better technologies. The Computer Internet community has demonstrated a remarkable ability to solve old problems with innovative, collaborative solutions while creating new opportunities and new paradigms. We want to apply this same system of collaboration, cooperation and camaraderie to empower the "Light Pollution" Internet community to solve the problems facing. We realized that within the "Light Pollution" community the sharing of information is more frequently done within academia or large group practices, colleague to colleague. Those in private practice, in more rural areas, or more remote countries often do not have access to this camaraderie that so often sparks new insights. We want to utilize the power of the Internet to create a meeting place and a forum where "Light Pollution" Internet Professionals from around the globe can exchange ideas, share insights, consider problems and find solutions.

Light Pollution Fact Sheet Our goal is to encourage quality lighting! We are NOT against night lighting. The 100 inch diameter telescope at Mt. Wilson Observatory, which overlooks the Los Angelas basin, is only 11% as effective as when it was built. This telescope is severely limited in its research capabilities because of light pollution. 1 billion dollars ($1,000,000,000) is wasted each year in the United States by lighting up the sky. This wasted light serves no purpose for safety, security or utility......it is simply wasted energy! We want to start NOW to preserve as best as we can the sky above Holmes Park and Hyde Observatory. Components of light pollution include: Light trespass - Spill light coming from another property. Glare - From seeing the bright filament of an unshielded light, troublesome and dangerous. Clutter - Excessive grouping of lights, causes confusion as well. Energy waste - Costing us over One Billion Dollars a year in the U.S.A. alone. Urban sky glow - Domes of light over cities. Blocks out faint objects such as the Milky Way, Nebula and distant galaxies. Only a few bright stars can be seen from the city. SOME TYPES OF LAMPS: Low Pressure Sodium (LPS) fixture produces a yellow tint.

Light Pollution Light pollution is one aspect of a wider range of pollutants. As part of the Electromagnetic Spectra , it causes a host of problems, ranging in seriousness from hardly at all to quite serious. Visible light is what we see with, the sun produces huge amounts of it during the day, and people complain about a tiny bit flashing outside their bedroom windows at night. Here one particular source is polluting a small number of individual people, and the best way to stop the pollution is to get something done about the individual light. As well as this, in towns, cities, and along motorways and main roads street-lights put large quantities of light up into the air. This makes a glow over cities, obscuring the stars, meaning that observatories have had to move away from where people are, to places where the light polution is at a minimum.

Light Pollution in Italy Inquinamento luminoso in Italia by Pierantonio Cinzano Italiano Introduction to light pollution Italian sources of light pollution ... University of Padua All rights reserved Light pollution is the alteration of natural light levels in the outdoor environment due to manmade light sources. Reported adverse effects of light pollution involve the animal kingdom, the vegetable kingdom and mankind. One of the most noticeable effects of light pollution is the increase in night sky brightness. The light wasted upward by the night-time outdoor lighting, in facts, lights up the atmospheric particles and molecules producing a luminous background which obstructs the vision of the night sky. This causes the loss of perception of the Universe where we live. This Web Site has the purposes to give you information on the problem of light pollution in Italy and on its possible solutions. The Proceedings of the Convention "Light Pollution and the Protection of the Night Environment - Venice: let's save the night" are collected in a book of 356 pages, edited by Pierantonio Cinzano and published by the Light Pollution Science and Technology Institute (ISTIL) with the support of UNESCO-ROSTE. The book reviews the many aspects of light pollution with a simple language through contributions of authors of international relevance: the importance of stargazing to man throughout the centuries, the situation of the night sky in Europe and Italy, ecological consequences of artificial night lighting, teaching light pollution at school, technical measures for an effective limitation of its effects, controlling light pollution in Eastern Europe and much more.
