Cirrus bands to east and to west. Low-L unit 0 found with tape complete and popped out. Removed L00027. Tape L00028 running in unit 1, loaded L00029 into unit 0. Wed Apr 20 17:15:59 GMT 1994: Patrol Start MKIII COMMENT: Wed Apr 20 17:17:44 GMT 1994 Since cirrus may obscure sun part of the day, will wait for then or noisy sky to do dark scan. Wed Apr 20 18:01:29 GMT 1994: Filemark-Calibration COMMENT: Wed Apr 20 18:04:12 GMT 1994 Program may have crashed. Lost console while listing a file during rlogin session.

MKIII COMMENT: Wed Apr 20 19:31:18 GMT 1994 Changing limb and ref exposures to 27. Wed Apr 20 19:40:43 GMT 1994: Patrol Start DPMON COMMENT: Wed Apr 20 19:52:17 GMT 1994 Placed dichroic heat-rejecting glass in front of Lyot stop.
