Is there any way to find out what sky surveys are *currently active?* I've asked a question about active sky surveys that might intercept a 2% of 4π patch of sky in the next six months and potentially record this dim (+22 to +26 magnitude) object.

I've added a bounty with about one more day on the grace period, the only thing helpful was a comment that suggested I ask for a "database of surveys".

Are there any pages that list at least major active surveys? That would be a start at least.
If you really just want a list, Wikipedia has a pretty good page on astronomical surveys. 

For some comprehensive information, including some tabulated values (such as sky coverage for each survey), try this paper from S. G. Djorgovski et al.
