Tonight's Sky for July 11: Solar Storm, Round 2?

Yesterday, NOAA predicted a 40% chance of a geomagnetic storm for observers at high latitudes. Well, the space weather wizards were right on track (and perhaps a little conservative with hindsight) as aurora were reported as far South as approaching the 40 degrees North latitude mark. Now, NOAA is predicting that the storm could pick up strength again tonight as the solar wind that set it into motion yesterday continues to build strength. Needless to say, keep an eye on the sky if it's clear tonight and you live in the Northern United States.
