I was just reading my copy of Sky & Tel (US version, for those that have been following my thread, I have now got the last two copies no problems
). In the editorial they mention a worldwide project to count the number of stars visible to the naked eye in the constellation of Orion between February 25th and March 8th. At the moment this would be pretty easy in Melbourne....zero! Hopefully it clears up in the next few days and I can get out there and make a contribution.
