Backing it up just a few hours, here's another way to launch the International Year of Astronomy. The Platisphere activity uses January 1, IYA2009, at midnight as a reference point for finding the positions of the north circumpolar stars throughout the year. It uses a paper plate akin to a planisphere, except all the answers aren't provided on the perimeter of a preprinted dial. See the Platisphere activity at http://analyzer.depaul.edu/paperplate/Platisphere.htm.
By the way, as the ball drops at midnight, Sirius is nicely positioned in the south, and the Kids are high at midnight. That is, the young goats forming the isosceles triangle in the constellation of Auriga are nearly overhead.
I could not get the link to work as is.......but after pasting it into my search bar then deleting the lone period on the end of the URL it works fine.
