Here is some more work on Saturn in April. On this date conditions were good
enough for long enough to get an hour and a half of data. I have presented 3 RGB
images (no L), the corresponding greens, at about 40 min intervals, and
contrast-exaggerated versions of the green images. There seems to be a bright
spot in the south temperate zone at about II=265. This is arrowed, though it is
not clear in the last image. There is probably another following it at about II=280.
