comet collision
- U. Rochester infrared images of aftermath of explosions
- Saturn in and out of methane band
- out of methane -- 1250 nm -- just like visible appearance
- icy ring particles reflect sunlight
- clouds reflect from disk
- in methane -- 2230 nm -- disk disappears!
- methane in atmosphere absorbs sunlight before it can reach clouds vg spectrum, vg cloud levels
- Jupiter at various wavelengths
- 3 spots in S. hemisphere show up clearly in methane bands at 1700, 2180, and 3500 nm
- high clouds lifted into stratosphere by 3 explosions
- scars, size of earth, lasted many months
- unrelated high clouds at poles seen clearly at 3500 nm
