This is a handy graph for figuring out if the Kp index might be elevated enough to check for aurora.
Check http://www.swpc.noaa.gov/pmap/ to see if it’s actually worth going outside. This link goes to the general SWPC page. You may want to actually bookmark the northern or southern hemisphere map, or check out their pilot program, OVATION (which is prettier, but I don’t know much about its accuracy)
