Mag, so you think the cities along the Nova Scotia coast are part of the Geo-Political overlay rather than the space image?

the white line is the edge of the field of view for that camera. the slope of the line shows the track of the satellite. Anyways, you can see the same thing on the evening news weather report, look at the rain data for the whole country. you can faintly see where theres a line just off the east coast and through the midwest. these are where they overlap two satellite images and can't perfectly match gain. why is that edge so bright? bad pixels on the ccd? shutter effect? Maybe they use a one piece shutter and that side is exposed the longest?

If you go to the site UT posted, and look at the very large, hi-rez versions of the pics, you will clearly see that the white edge in the pics is indeed the Eastern extent of the image, with the rest of the background being the geopolitical overlay. It shows up much better in the hi-rez versions of these same pictures.

They also have some annotated before and after shots that are kind of neat.

Yes....those white spots aren't cities, they're just places where the map has drawn a lot of near-fractal "krinkly bits" (term coined by Slarty Bartfast) following small inlets, coves and islands along the shoreline. Since they're all white, it appears to make "cities".

I just think it's interesting how the entirety of the United States was completly cloudless at exactly 23:15 Eastern time on August 14th.

Heh heh. :)

As I recall, it was a very nice day...I was up flying just before the outage, because it was the first clear day in what seemed like weeks.

Be that as it may, I think someone needs to review his knowlege of US geography before he Photoshops. That patch of RGB(0,0,0) (the one that doesn't match any of the other dark areas in the image) blobbed out over a much bigger area than the blackout did.

Remember that! Not even the clouds can protect you from W.:rolleyes:

With the "blackout" area being so black, it looks more like a giant flood (that somehow covered the appalachians?) since thats the color of the water, not the dark ground...
