While TPE (yet) does not not predict auroras or have geodetics for them, folks who use it will probably be interested in the potential for a significant magnetic storm tonight. There was a CME on Saturday, which was predicted to arrive here on Monday. But it apparently arrived at 1430 or so UT today and caused a severe, G4 magnetic storm. It has subsided now but I see forecasts indicating the the Kp could rise to 7 between 11 and 1:000 a.m. Eastern time. That would make it possibly visible down to the mid latitudes of the US.
