Come learn how reducing light pollution can make us safer, healthier, and wealthier while also reconnecting us with the infinite universe that surrounds us. This interactive session will help you determine the best outdoor lighting technology that fits your needs.
- 4:30-6:30 - Astronomy Trivia and Family-friendly Activities including crafts and mini science projects
- 7:00-8:00 - Effect of Artificial Light at Night on Juvenile Salmon with Roger Tabor, USFWS Fish Biologist retired
- The Seattle Metropolitan area is home to over 4 million people and over half of Washington’s population. It also supports several commercially and culturally important populations of salmon. Urbanization in this area can have numerous impacts on salmon and aquatic ecosystems including the impact of artificial light at night (ALAN). Many of the impacts from urbanization have been well studied; however, the impact of ALAN has received little attention until recently. Of particular interest is the impact of ALAN on juvenile salmon and how it may impact their migrations and vulnerability to predation. In this presentation, Roger Tabor (U.S. Fish and Wildlife Service, retired) will overview past and ongoing research and discuss ongoing efforts to minimize its effects.
- 8:00-8:30 - Community Science Walk and Survey
- 8:30-10:00 - Astronomy by the River with telescopes and guided stargazing!
Suggested donation of $5-$10 per attendee. RSVP's are helpful but not required.
