Fri Oct 13 20:40:27 GMT 1995: Patrol Start WEATHER COMMENT: Fri Oct 13 20:41:15 GMT 1995 Cirrostratus cleared, starting observations. DPMON COMMENT: Fri Oct 13 20:49:25 GMT 1995 Now that the O1 is very clean the background sky appears so dark that we are getting lots of yellowish pixels scattered around the sky, especially off the West limb. They are the same color aas those on the image of the occulting disk and must represent extreme dark.

The longer exposure time reduces the yellowish pixels that were scattered around the background sky due to sky darkness.
