Title The Light at Night Mapping Project: LAN MAP 1, the Tucson Basin Type Journal Article
Year 2012 Publication Society for Astronomical Sciences 2012 (proceedings) Abbreviated Journal (up)
Volume 31 Issue Pages 139-145
Keywords Skyglow
Abstract Tucson, Arizona, once billed as the Astronomical Capital of the World, has long been home to at least ten major astronomical institutions and facilities. The region also hosts numerous productive amateur observatories and professional-amateur astronomical collaborations. In spite of the implementation of progressive night time lighting codes, the continued growth of the region has arguably deprived Tucson of its title, and threatens the future of some if not all of these facilities. It has become apparent that there are several difficulties in regulating this lighting environment. It is not easy to model the actual effects of new or changed lighting fixtures, there are compelling economic conflicts that must be considered, and adherence to various guidelines is often ignored. Perhaps the most fundamental problem is that there have historically been no comprehensive measures of either light at night or sky brightness over the extended growth areas. What measurements do exist are inhomogeneous and poorly accessible spot measurements at some observatory sites. These have little to tell us about the actual light distributions in the overall region, and rarely are informative of the specific light sources that offend the observatory sites. Tucson remains, for the time, an important astronomical resource. Because of its astronomical and lighting code circumstances, it is an interesting and valuable laboratory for studying these issues. In this paper we introduce an innovative new 5-year project to comprehensively map both sky brightness and associated artificial lighting over extended areas of development in the vicinity of important astronomical institutions. We discuss the various vectors employed in data collection; we outline the protocols used for each methodology, give examples of the data collected, and discuss data analysis and conclusions. This program has been underway since January 2012, and has already produced results of interest to professional and amateur astronomers alike.

Title Effect of light pollution on night sky limiting magnitude and sky quality in selected areas in Malaysia Type Journal Article
Year 2011 Publication Sustainable Energy & Environment (ISESEE), 2011 3rd International Symposium & Exhibition Abbreviated Journal (up)
Volume Issue Pages 233-235
Keywords Skyglow
Abstract We investigate the effect of light pollution as the important considerations that limits the quality of the sky brightness for the astronomical purpose. Selected sites that covered: Klang, Selangor, Merlimau Melaka, Ipoh, Perak ad Kuala Lipis, Pahang, Malaysia have been chosen in order to investigate the visual estimation magnitude for observing visible stars. The results also based on Bortle scale theory provides glimpses of potential quality of night sky quality that is currently lost in most urban area in Malaysia. From the results, Kuala Lipis, Pahang is the best candidate site for astronomical purpose with the range of magnitude from 20.3 till 21.5 magnitudes per arc second. Some recommendation for a better solution will also be discussed.

Title National education program for energy efficient illumination engineering Type Journal Article
Year 2011 Publication Proceedings of SPIE Eco-Photonics 2011, Strasbourg, France, March 2011. Abbreviated Journal (up)
Volume 8065 Issue Pages 80650Q-1

Abstract About one-third of outdoor lighting escapes unused into the sky, wasting energy and causing sky glow. Because of excessive sky glow around astronomical facilities, the National Optical Astronomy Observatory has a strong motivation to lead light pollution education efforts. While our original motivation of preserving the dark skies near observatories is still important, energy conservation is a critical problem that needs to be addressed nationwide. To address this problem we have created an extensive educational program on understanding and measuring light pollution. A set of four learning experiences introduces school students at all grade levels to basic energy-responsive illumination engineering design principles that can minimize light pollution. We created and utilize the GLOBE at Night citizen science light pollution assessment campaign as a cornerstone activity. We also utilize educational activities on light shielding that are introduced through a teaching kit. These two components provide vocabulary, concepts, and visual illustrations of the causes of light pollution. The third, more advanced component is the school outdoor lighting audit, which has students perform an audit and produce a revised master plan for compliant lighting. These learning experiences provide an integrated learning unit that is highly adaptable for U.S. and international education efforts in this area.
