Stripey, check these out. One of these should have what you're looking for.
surely you have Skywarn but how about http://www.skywarn.de/
which has a lot of good links. Never mind the language barrier. Trial and error should suffice.
Sorry I don't have the time to search thru all of these to find one showing the world from the top....but I'm certain it's in there somewhere. J
Okay, Bush lied, I lied. Came across this https://www.fnmoc.navy.mil/PUBLIC/
slide down to Satellite and select North Pole. I'm not getting the SAT images from there so will keep looking. Let's try NOAA-12 ....chanels 1, 3 and 4 :

Nope, that silly SAT is flying the wrong way.
maybe http://earthobservatory.nasa.gov/Missio ... a/ModisDB/
Na, that aint it. But this one http://www.goes.noaa.gov/f_g9.html
should come in handy when the asteroid hits. This one http://www.osei.noaa.gov/
is one of my all time favorites. I like the Unique Imagery part. Might be something for you.
