EAC and Desert Sky Gazers present lecture on Dark Skies Initiative

By Jeanné Schaser

THATCHER, AZ—Eastern Arizona College’s Discovery Park Campus, in partnership with the Desert Sky Gazers amateur astronomy club, will present “Light Pollution and the Dark Skies Initiative” on Saturday, December 5, at 6:30 p.m., in the Jupiter Room of Discovery Park Campus. At this free, family friendly presentation, Dean of Discovery Park Campus Harry Swanson will share NASA slides of the nighttime Earth and will present a short video on the importance of regulating unwanted and unneeded light at night.

“As many already know, the night sky is difficult to observe during moonlit nights,” says Swanson. “What they may not have known is that stray reflections from yard lights, street lights, and parking lots also destroy ‘seeing’ at night. This lecture may give some ideas how to help alleviate this problem.”

“I’ve always known that stray light adversely affects the ability to see at night,” continues Swanson. “After all, just think how long it takes your eyes to adjust to the night after walking from a brightly lit room. What I was surprised about is that we often have a false sense of security about the effectiveness of security lights. In our video, produced by the National Optical Astronomy Organization, you can see how a burglar security light actually makes it harder to see the intruder because of glare. I think this information will change your life, so please join us for this lecture!”
