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.

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.

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.

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.
