Note: As of August 1, 2011, the Interactive Sky Chart is working again.
Our popular Interactive Sky Chart will be unavailable for an indeterminate period. The server that hosts it started to become increasingly unreliable last month, and it appears to be completely dead now.
We are looking into porting the Sky Chart to a different platform. Unfortunately, this is a complex program that's tied to some obsolete software, so it's not easy to move to a modern computer. Stay tuned for more developments, and sorry for the inconvenience.
