6th Globe at Night Campaign Revisited (March 24 - April 6, 2011)

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

The Globe at Night world ligh pollution survey is being revisited this year. The survey is being re-run from 24 March to April 6 (starting tomorrow night). Everyone can be involved, hopefully students and teachers too. 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) 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 or NanoSail-D.

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.

There is a pod-cast on light pollution from 365 days of astronomy and a powerpoint presentation that explains about light pollution and how to do the sky survey, and special activities for kids. So go on, get out and have a go!
