Just a Reminder about the Globe at Night Light Pollution Survey
Globe at Night, the international light pollution survey, is currently running until January 23. The Survey is running four times this year, with January 14-23 followed by February 12-21, March 13-22 and April 11-20. Visit their website for easy to follow instructions and charts to estimate how dark your sky is.
Basically, an hour or so after sunset (8-10 pm) head out, look to the north to find Leo, (if you are in the northern hemisphere) or south to find Crux (for us southern hemisphere types) or Orion (for everybody) then check how many stars are visible, and report your observations. It's a great excuse to get outdoors and look at the sky. You might even see the International Space Station or an Iridium flare.
This year you can submit your results a smart phone or tablet. To do this, you can use the web application at www.globeatnight.org/webapp/. Globe at Night is also on Facebook and Twitter.
