In case you missed it, Monday night in the northern latitudes
Some incredible photos of last week's major aurora display. I hear there were sightings as far south as Arizona, and I wonder: If I had driven up into the mountains above the cloud layer covering the LA basin, would I have seen flickering lights off in the north? (Presumably not. I'm sure if someone had seen the aurora from Mt. Wilson, it would have been mentioned in one of the articles I'd read.)
