Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Fri May 6 16:46:34 GMT 1994 Year: 94 Doy: 126 Observer: yasukawa COMMENT: Fri May 6 16:46:42 GMT 1994 Cool, clear, light south breeze. Temp = 46 F. Low-L running this morning, cranking data onto L00037 in unit 1 still. Rewound video tape for tonight's "hunting" expedition. Fri May 6 16:52:35 GMT 1994: Patrol Start Fri May 6 17:02:19 GMT 1994: Filemark-Calibration MKIII COMMENT: Fri May 6 17:05:17 GMT 1994 Loaf of bread display high this morning. Lots of haze in saddle apparently to altitudes higher than Mauna Kea summit, sky a dirty white near sun. DPMON COMMENT: Fri May 6 17:08:09 GMT 1994 Daystar filter feels warm to the touch, probably working OK. Disc looks barren, but may try running thru a temperature range of 1.0 to 8.0 to see if contrast improves at other than 5.00 temp. setting. DPMON COMMENT: Fri May 6 17:12:13 GMT 1994 Daystar set to 1.0 DPMON COMMENT: Fri May 6 17:56:03 GMT 1994 Daystar temp set at 2.0 MKIII COMMENT: Fri May 6 17:57:55 GMT 1994 Calibrating channel 1 Fri May 6 18:02:28 GMT 1994: Filemark-Calibration DPMON COMMENT: Fri May 6 18:36:16 GMT 1994 Set Daystar temp to 3.0 Fri May 6 19:02:25 GMT 1994: Filemark-Calibration DPMON COMMENT: Fri May 6 19:09:34 GMT 1994 Set Daystar temp to 4.0 COMMENT: Fri May 6 19:14:13 GMT 1994 WWVH check, Low-L clock right on. Fri May 6 19:37:03 GMT 1994: Patrol End COMMENT: Fri May 6 19:42:48 GMT 1994 Reconfigured dome slot. Brushed front surface of MKIII O1. MKIII kept scanning. DPMON COMMENT: Fri May 6 19:43:53 GMT 1994 Set Daystar temp. to 5.0 Fri May 6 19:44:17 GMT 1994: Patrol Start Fri May 6 20:00:25 GMT 1994: Filemark-Calibration DPMON COMMENT: Fri May 6 20:16:54 GMT 1994 Set Daystar temp to 6.0 MKIII COMMENT: Fri May 6 20:22:09 GMT 1994 sky very noisy. COMMENT: Fri May 6 20:27:10 GMT 1994 Guider declination reset itself. Repointed. Fri May 6 21:00:27 GMT 1994: Filemark-Calibration DPMON COMMENT: Fri May 6 21:02:43 GMT 1994 Set Daystar temp to 7.0 Fri May 6 21:05:01 GMT 1994: Patrol End Fri May 6 21:09:25 GMT 1994: Patrol Start DPMON COMMENT: Fri May 6 21:09:37 GMT 1994 Tried varying exposure in limb mode to see if we could converge on the same exposure for limb and disk mode. Using 50 for limb darkens the background and causes some of the fainter small prominences to get very faint. Brighter prominences do not suffer as much. DPMON COMMENT: Fri May 6 21:29:43 GMT 1994 Daystar teemp set at 8.0 DPMON COMMENT: Fri May 6 21:41:32 GMT 1994 Doing some manual exposure variation for a while. Fri May 6 21:46:56 GMT 1994: Patrol Start DPMON COMMENT: Fri May 6 21:52:11 GMT 1994 Daystar temp set back to 5.0 i May 6 22:02:20 GMT 1994: Filemark-Calibration Fri May 6 22:10:03 GMT 1994: Patrol End DPMON COMMENT: Fri May 6 22:19:39 GMT 1994 Captured limb and disc images for David Elmore with limb exposure at 50, # summed: 4, and disc image at temp = 5.0, exposure = 50, and # summed = 4. COMMENT: Fri May 6 22:21:37 GMT 1994 Activity report: qp: 40; 54; 133; 220; 282; 315; No coronal activity Tapes: MKIII: H00758 DPMON: P00059 LOW-L: L00037 in unit 1 DPMON COMMENT: Fri May 6 22:23:45 GMT 1994 Daystar temperature test summary: 5.0 looks best. Will need to wait for a day with more structure on disc to determine any further improvement.
