It's hard to believe the 24/7 news media wasn't all over this one coming and having everyone head for their basements, with their TV's of course. I could see 24 hour coverage of projected tracks and who is in the most danger.
Unless of course this one took everyone by surprise, and no one knew it was coming. Which begs the question, will we really know for sure a big one is coming? Seems I read somewhere it's hard to see them when they're coming straight at us because there is no movement to see.
It will be interesting to see what comes out of this one when they find it.
That would suppose there was enough advanced notice. The area is very vast and not that much in the way of resources is allocated to such monitoring. We think we have charted the nearby "planet killers" but not much below that level......
