The lead image seems to be continually updating to the current GEOS image. Based on <li>Dabom's post at 10:17 PM EDT, having the B&W teardrop and a timestamp of 0000 Zulu, <li>and the moon's orbital period of approximately 25 hours,
if it is the moon, it may be visible again in the 0100 Zulu image for 8/29/02.
If I recall, the difference is 5 hours, so sometime between 8:00 PM and 10:00 PM EDT, the new image should be there. Look for a timestamp of 0100 on the first image of this thread. If you see a blob, it was the moon. Lack of a blob does not rule out the moon, as I am unsure if the timing of the shot is exactly the same.
The teardrop shape rather than a perfect circle may be due to the scan rate for the image. If it takes a few minutes to produce the image, the motion of the moon through space will cause a blurring effect, similar to taking a picture of a moving object without panning and a slow shutter speed, hence the teardrop.
