I live out here in the Southwest and its still sunny here...did they find this last night and only recently compute its trajectory, or was it discovered with radio telescopes? Probably a stupid question, but I am trying to reconcile the discovery just hours ago with the fact that its a bright sunny day here, and has been for the last 10 hours.
