Globe at Night Light Pollution Survey for March 11-20, 2015

The southern evening sky around 9:00 pm daylight saving time in March in Australia.

Globe at Night, the international light pollution survey, is running once again. Its third survey this year is on from from March 11-20 (it's US HQ'd, that means we Australians/New Zealanders have until the 21st).

There is now a survey every month of the year. 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 Orion (if you are in the northern hemisphere) or south to find Crux (for us southern hemisphere types) 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.

You can submit your results on the web, or via 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.
