MKIII COMMENT: Wed Sep 14 21:01:30 GMT 1994 BUG removed most of the effects of the wisp of cloud that tainted 2032 scan. Putting that into HISTORY.

COMMENT: Wed Sep 14 21:48:06 GMT 1994 Talked to Fisher earlier this morning and gave him the bad news that chances for obs today looked mighty slim. He just called back very excited that our persistence paid off and we managed to get him an NMAP for today. The Houston crew got very excited when our FAX arrived.
