APL scientists have produced this image of the TIMED spacecraft's observations of the March 29, 2006, total solar eclipse. The data was acquired by TIMED's Global Ultraviolet Imager (GUVI) instrument as the eclipse progresses.

The first of the two orbit swaths (the one furthest to right in the image) shown in the image does not occur in the region of the eclipse. The position of the center of the moon's shadow, or umbra, is shown as it moves from Brazil across Africa.

In the second swath (the one furthest to the left of the image), GUVI images the region of the moon's shadow on Earth. During that time the TIMED spacecraft flies past the shadow region and sees the dramatic decrease in the temperature and brightness of the upper atmosphere where the moon's shadow falls. This is indicated by the dashed line in the second swath where GUVI looked toward the east to see the affected region.
