Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Wed Dec 14 17:12:43 GMT 1994 Year: 94 Doy: 348 Observer: yasukawa WEATHER COMMENT: Wed Dec 14 17:13:09 GMT 1994 Cold, clear, light south wind. Temp=41F. Wed Dec 14 17:18:35 GMT 1994: Patrol Start Wed Dec 14 17:24:07 GMT 1994: Patrol End DPMON COMMENT: Wed Dec 14 17:29:09 GMT 1994 Changed occulting disc from 1981 to 1991 (#4 to #3). Wed Dec 14 17:30:06 GMT 1994: Patrol Start Wed Dec 14 18:00:55 GMT 1994: Calibration DPMON COMMENT: Wed Dec 14 18:27:38 GMT 1994 Image wierded out. Reset Plessey to attempt fix. MKIII COMMENT: Wed Dec 14 19:00:16 GMT 1994 Experienced guider oscillation. Reset guider to stop it. Oscillation affected mkiii data scans. MKIII COMMENT: Wed Dec 14 19:14:22 GMT 1994 Stopping mkiii to work on channel 0 alignmant. Wed Dec 14 20:01:05 GMT 1994: Calibration MKIII COMMENT: Wed Dec 14 20:34:26 GMT 1994 Scanning with slot mask in, opal in, at the "aligned" detector position to document the pixel heights on exabyte tape. MKIII COMMENT: Wed Dec 14 20:40:53 GMT 1994 Took 2 scans of slot mask data then stopped to remove slot mask and check alignment. Wed Dec 14 21:01:00 GMT 1994: Calibration Wed Dec 14 22:01:03 GMT 1994: Calibration MKIII COMMENT: Wed Dec 14 22:04:06 GMT 1994 OK, got what may be the best alignment after hours of adjusting rotation and up/down. Now detectors look "square" in their mount, and the P+S and P-S traces for both masked and no-mask look about as best as I can get them at any one adjustment setting. MKIII is put back together. Will run a CORRECT and then CALIBRATE. MKIII COMMENT: Wed Dec 14 22:15:47 GMT 1994 CORRECT pau. Calibrating channel 0. MKIII COMMENT: Wed Dec 14 22:38:47 GMT 1994 UGH! I forgot to document the new height with the mask in after settling on a final alignment. I'll go back and do it. MKIII COMMENT: Wed Dec 14 22:45:46 GMT 1994 Inserted slot mask and opal. Taking scans to exabyte to document pixel heights. MKIII COMMENT: Wed Dec 14 22:52:11 GMT 1994 Removing slot mask and opal. WEATHER COMMENT: Wed Dec 14 22:52:33 GMT 1994 Clouds??? UGH, in cirrus. MKIII COMMENT: Wed Dec 14 22:57:31 GMT 1994 OK, MKIII restored to all its glory. Will attempt a fer more coronal scans, but cirrus may have gotten me for the day. Wed Dec 14 23:00:57 GMT 1994: Calibration WEATHER COMMENT: Wed Dec 14 23:14:32 GMT 1994 In cirrus deck that is mixed thin and moderate and is pretty extensive now. COMMENT: Wed Dec 14 23:15:23 GMT 1994 End observations. Activity Report: QP: 43-50; 130; 240; No coronal activity detected. TAPES: MKIII: H00912 being sent back to Boulder today for alignment evaluation. DPMON: P00229 LOWL: L00146 in unit 0 ALIGNMENT VIDEO also to be sent back with H00912.
