Changed occulting disc from 1931 to 1921 (#9 to #10).

DPMON COMMENT: Tue Jun 21 17:27:27 GMT 1994
DPMON crashed when going to manual to change occulting disc.
Had to reboot Sparcstation to recover.  Symptom of crash is
becoming quite regular, Camera remains BUSY (system crashes there,
camera not actually active).
Recycling tape # P00088.
Saved earlier logs and recovered them after reboot.

O2B mic set from 4.95mm to 5.05mm as per latest focus test results
decision by Alice.

MKIII COMMENT: Tue Jun 21 17:45:51 GMT 1994
Starting Calibrate/Correct/Calibrate routine as agreed upon in
Boulder.

Tue Jun 21 18:02:20 GMT 1994: Filemark-Calibration

DPMON COMMENT: Tue Jun 21 18:19:52 GMT 1994
Changed Lyot stop to 0.7" paper stop w/ no hr filter,  O2B focus
from 5.05mm to 3.85mm, and edited disc exposure to 50ms.

MKIII COMMENT: Tue Jun 21 18:31:19 GMT 1994
Cal/Correct/Cal pau.  Running a dark scan instead of "NOAA" scan.

MKIII COMMENT: Tue Jun 21 18:44:12 GMT 1994
VDIFF of before- and after-correct coronal scan reveal no
significant difference.

DPMON COMMENT: Tue Jun 21 18:48:28 GMT 1994
Resumed limb-preferred setting:  O2B at 5.05mm, 0.8" Lyot stop 
with hr filter, disk exposure at 120ms.

Reconfiguring dome shutter.

Tue Jun 21 19:45:45 GMT 1994: Patrol Start

COMMENT: Tue Jun 21 19:46:00 GMT 1994
Tried to check seeing in dome with Questar and solar filter
but there are no good visible features on disk that allowed
me to determine seeing one way or the other.

MKIII COMMENT: Tue Jun 21 19:48:49 GMT 1994
Will try changing Channel 1 phasing by 22.5 degrees to try to
equalize U and Q.  Micro B channel phasing set at 5 to start.

MKIII COMMENT: Tue Jun 21 19:53:25 GMT 1994
Setting Micro B channel phasing to 7 moved phasing to
approximately -22.5 degrees from 0 degrees (peak).

DPMON COMMENT: Tue Jun 21 19:57:38 GMT 1994
DPMON crashed again.  Will have to save log and reboot.  Starting
new tape this time.  End P00088, loading P00089.

COMMENT: Tue Jun 21 20:10:21 GMT 1994
Restored logs.

Tue Jun 21 20:10:46 GMT 1994: Patrol Start

MKIII COMMENT: Tue Jun 21 20:18:34 GMT 1994
Looks like Q and U NMAPs are about equal in pB.  I will leave
phasing as is for tomorrow, to see what channel 1 looks like
in better sky.  I'll change it back on Thursday.
