Attendees at the 223rd AAS meeting in Washington, DC, are invited to attend two special events on Sunday and Monday related to light pollution and observatory site protection.
Light Tag Definition: Relates to the Committee on Light Pollution, Radio Interference, and Space Debris and their mission to both act as a clearinghouse and combat the problem.
The American Association for the Advancement of Science (AAAS) Dialog on Science, Ethics and Religion program (DOSER), will air the movie "The City Dark" on 10 May 2012 beginning at 5:30 pm at the AAAS Headquarters in Washington, DC.
AAS members in the local region are welcome and encouraged to attend. After the screening, there will be a panel discussion on light pollution and its impact on humans, both physically and culturally. AAS President, Debra Elmegreen will also participate in the panel discussion.
GLOBE at Night, now in its 6th year, encourages astronomers and citizen-scientists worldwide to record the brightness of the night sky to help create a global map of light pollution. During two weeks of moonless evenings, observers compare the appearance of a constellation (Orion in February/March and Leo or Crux in March/April) with the view depicted on seven charts showing progressively fainter stars. They then go online to report their date, time, location, and the number of the chart that best matches their view of the constellation. New this year: Observers with smart phones or tablets can submit their measurements from the field in real time!
