Good find. Thanks! The university will also email you with high activity alerts, etc. You can go here for all of that:http://www.pfrr.alaska.edu/aurora/index.html
Also, the U.S. National Oceanic and Atmospheric Administration (NOAA) has nearly real time auroral satellite data/maps available here:http://www.sec.noaa.gov/pmap/
I use this "real" time info to decide whether it's worth heading out into the cold night or not.
Cheers from Juneau!
