Re: satellite photo showing nightfall

Please have a look at this photo of nightfall over central Europe
that was sent to a friend of mine by a former student who is now in
Navy satellite imagery. Can anyone tell me if this is a single image
or one that was pieced together using a number of images and then
visually enhanced?

My first impression is that it is _greatly_ enhanced. The relief of the
ocean floor, the rich greens, the pure white snow cover.... and besides,
twilight is almost an hour long and would cover almost 15 degrees of
longitude.

In any event, it's a great pic...
