GLOBE at Night - Now Through May 8

The GLOBE at Night citizen science program is underway again. This is an easy way for people to go out and measure the brightness of the night sky. I did so myself earlier this evening:

This is their last campaign for the year, so if you are thinking of trying it out, don't wait to participate. It is really quite easy and the results are helpful. Go on over to their website http://www.globeatnight.org/ to see how to join in.

Soon I'll be blogging about how you can use your cell phone to make night sky brightness measurements. Look again later this week.
