I grew up watching more than a few auroral displays. Although often stunning, most of the video these days is time lapse while the real thing unfolds in a much more stately fashion. Improvements in video cameras are providing the sensitivity necessary for real time work Here's a recent example.
they also stream from a camera near Fairbanks, Alaska .. so if you hear about an alert, check them out. Lots of places for aurora status... this is good for Alaska and if you live in a place that is well positioned, but you don't like constantly checking, here's a ($) alert subscription service and spaceweather's email sign up alert for a variety of events. spaceweather.com is a great place btw.
