Satellite: NOAA-17, one of NOAA's 850km-high (530 mile-high) Polar Orbiting satellites.
Hurricane Ivan and Tropical Storm Jeanne
A Tale of Two Storms
In the higher-resolution image of the eye just below, you can even see the structure of the powerful eyewall, where the strongest of the winds occur.
The image directly below was taken by NOAA-16 on a flyover starting at 3:35pm EDT.
You can see right down the throat of the hurricane, into the literal calm in the eye of the storm.
(Ignore the "wiggles" on the left side of this image--NOAA-16 has some flight control problems at the moment.)
And yes, Ivan is very bad news for New Orleans.

You can see Ivan's cumulative path from the previous few "Images of the Day".
