NOAA live Aurora forecasting map.

Even better than the older Spaceweather's one, which, although the image says that the server is being upgraded, seems more likely that the usefulness of their separate site has been diminshed.

NOAA's Spaceweather site (you seriously need to geek out on their site with all the data they have) shows a major X-1 flare was ejected from the Sun about 24 hours ago (early morning March 5th 2012), but they say it will likely miss the Earth.  Still, hoping for an Aurora Borealis far South enough to be visible in Washington and Oregon in another day...fingers crossed.

This is a link directly back to NOAA's live updating image, so it will change constantly.
