8/19/2003: Night sky during blackout

I think the best state to look at is New York. Compare the island on both days. Almost the entire state is dark on the 14th.

What is the white line on the right?
Undertoad Tuesday Aug 19 12:52 PM
In trying to find out what the line is, I found this page

Looks like one of those circular radar-sweep thingies you see in movies.
SteveDallas Tuesday Aug 19 01:10 PM
My first instinct was that the white line would be the terminator (the division between night & day), but it's not positioned correctly. The 9:03 image shows MORE on the "night" side rather than less.

Goes to show what an educated idiot I am, but I thought the line was the edge of earth, ya know it being flat and all:p

On the other hand, if it is a radar-sweep thingie, it's moving in the direction of its trail.

Both radar and sonar have those sweep lines but that looks like a shutter curtain from a camera. I doubt if they use a regular camera, more likely an array of light receptors like a digital camera. The receptors are probably very sensitive and have to be shuttered to prevent streaking. But I'm only guessing

No, Juju. It's a day apart.

maybe it was raining in outer space when they took these pictures and it's the windshield wiper on the shuttle?
juju Tuesday Aug 19 05:01 PM
Ohh, I get it! I only looked at the time.

I suspect the "white line" is in fact the edge of the image as received from the satellite. The costal outlines and poltical borders are supplied by another ground based image on which the satellite image is superimposed. Notice nothing other than the background map image is displayed on the other side of the line.

Mag, so you think the cities along the Nova Scotia coast are part of the Geo-Political overlay rather than the space image?
gossard187 Tuesday Aug 19 09:56 PM
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.

Where are all the clouds?

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.
MaggieL Saturday Aug 23 12:40 AM
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.
