Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Thu May 5 16:49:22 GMT 1994 Year: 94 Doy: 125 Observer: yasukawa COMMENT: Thu May 5 16:49:33 GMT 1994 Cool, clear, brisk southeast wind. Temp = 46 F. Thu May 5 16:56:05 GMT 1994: Patrol Start DPMON COMMENT: Thu May 5 16:56:28 GMT 1994 Daystar filter back from repair. Will run a bit without it until all systems are running, then will shut down DPMON to reinstall it. COMMENT: Thu May 5 16:57:55 GMT 1994 Low-L running this morning. Rewound video tape and removed camera for the observation period. Will set it back up at the end of the observing day. Low-L taking data on L00037 in tape unit 1.

Thu May 5 17:38:02 GMT 1994: Patrol End DPMON COMMENT: Thu May 5 18:24:41 GMT 1994 Daystar filter installed, ProgramDefs modified to change Disc exposure from 1 to 100. Thu May 5 18:26:36 GMT 1994: Patrol Start DPMON COMMENT: Thu May 5 18:26:52 GMT 1994 Daystar temperature set at 5.00 COMMENT: Thu May 5 18:43:18 GMT 1994 Guider was oscillating. Cycled power and reset dec. to stop oscillations.

Exposure still heavy after a while of running, lowered it from 100 to 50 (where orange pixels go away). Will run at that exposure for disc images only. COMMENT: Thu May 5 19:27:37 GMT 1994 Opening top of dome before starting patrol. MKIII continues.

Thu May 5 21:03:57 GMT 1994: Patrol End Thu May 5 21:06:23 GMT 1994: Patrol Start MKIII COMMENT: Thu May 5 21:06:35 GMT 1994 Tried to see if contrast was being affected by the blue filter on the disc images. Exposure needed to be reduced to 20-25. No tape taken. Contrast did not change. There is not much on the disc to compare with in the first place--either that, or the filter is not at Halpha as it should be when set at 5.00. We'll have to go through the temperature tests again, maybe, when there are more features on thhe disc. Blue filter put back in the same orientation, and exposure used is 50 as is set in the ProgramDefs file. COMMENT: Thu May 5 21:21:28 GMT 1994 Guider declination hit a limit and reset itself. Repointed and reset guider. COMMENT: Thu May 5 21:52:01 GMT 1994 Guiding went bonkers again. repointed and reset. COMMENT: Thu May 5 21:56:33 GMT 1994 Wind is buffeting spar around.
