Yeah, "space storms" happen all the time, though this one is going to be a fairly big one. Even though we're winding down from the cleverly named solar max of '01, there's still going to be solar flares from time to time.
Now that the mainstream media has picked up on this stuff though, it saves me the trouble of having to endlessly promote www.spaceweather.com
all the time.
By the way, did anyone go see the Geminids last night? I pulled an artist and a couple designers out to the parking lot last night and we saw some decent ones.
