- This pair of images was obtained with the 0.8m telescope of the
- University of Texas McDonald Observatory on 20 Jul 1994 UT (19 Jul CDT)
- at 03:02 and 03:06 UT (10:02pm and 10:06pm CDT). North is up and east is on
- the left. An 893nm filter which isolates absorption by methane gas was
- used for the left image. This filter makes high cloud features appear bright.
- An 829nm filter was used for the right hand image. This filter is
- similar to what would be seen by a human eye.
- In the methane image, we see 3 bright impact sites.
- The impact site from piece L is on the right limb in this image.
- The G and D impact sites (merged together) are just to the left of the
- L site. The H impact site is near the east (left) limb. The Great Red
- Spot can be seen just coming over the east limb.
- Note the structure of the impact sites, especially the G site.
- The sites all clearly show a central spot, some dark space and then
- an arc of material to the southwest. In comparison, the 829nm image
- shows only the G and H impact sites since the L site is lost in the limb
- darkening. The Great Red Spot is not very easily seen in the 829nm
- image. Note, also, the difference in the polar hoods and the bands of Jupiter.

- This image was obtained by Dr. Chan Na (Southwest Research Institute),
- Dr. Wayne Pryor (University of Colorado) and Dr. Anita Cochran
- (University of Texas).
