The 5th GLOBE at Night Starts Next Week

The northern sky about 1 hour after sunset in Australia. Rigel and Betelgeuse outline the constellation Orion (click to embiggen).

Five years already? It seems like only yesterday the Globe at Night started surveying light pollution around the world. Well, it's on again, from 3 March to 16 March the world wide survey opens. Everyone can be involved, hopefully students and teachers too. Basically, an hour after sunset head out, look to the west to find Orion, then check how many stars are visible, and report your observations. It's a great excuse to get outdoors and look at the sky, see bright red Mars and take out the binoculars to look for Vesta. You might even see the International Space Station or an Iridium flare.

There is a pod-cast 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!
