Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sat Sep 24 16:41:31 GMT 1994 Year: 94 Doy: 267 Observer: koon WEATHER COMMENT: Sat Sep 24 16:41:37 GMT 1994 Clear sky, wind ~5 mph from the west, temp ~45 F. Sat Sep 24 16:46:08 GMT 1994: Patrol Start Sat Sep 24 17:02:08 GMT 1994: Calibration Sat Sep 24 18:02:09 GMT 1994: Calibration WEATHER COMMENT: Sat Sep 24 18:48:59 GMT 1994 Cirrus moving slowly over from the east. DPMON COMMENT: Sat Sep 24 18:52:59 GMT 1994 Switched to optimum disk image setup: 3.85 mm, 0.8" LS, 50 mms exp. Sat Sep 24 19:02:04 GMT 1994: Calibration DPMON COMMENT: Sat Sep 24 20:00:57 GMT 1994 Switched back to optimum limb image setup. WEATHER COMMENT: Sat Sep 24 20:01:18 GMT 1994 Occasional cirrus passing by. DPMON COMMENT: Sat Sep 24 20:01:43 GMT 1994 Nothing good on disk and limb to focus O2A by. MKIII COMMENT: Sat Sep 24 20:02:20 GMT 1994 Will look into tilt plate operation to see if it is working OK, may be able to improve design if necessary. COMMENT: Sat Sep 24 20:59:43 GMT 1994 Extended dome slot and turned on the ADR. WEATHER COMMENT: Sat Sep 24 21:00:10 GMT 1994 Getting cirrus from the west passing overhead. Sat Sep 24 21:02:04 GMT 1994: Calibration DPMON COMMENT: Sat Sep 24 21:54:02 GMT 1994 Diffuser runaway. Recycled plessy to correct. Sat Sep 24 21:58:03 GMT 1994: Patrol End COMMENT: Sat Sep 24 22:07:45 GMT 1994 Stopping obs to run MKIII tilt plate tests. MKIII COMMENT: Sat Sep 24 22:51:02 GMT 1994 Checked the operation of the tilt plates with Duc's help. They seem to work fine and I can't see any way that they could block the light beam, when they are out they are clear of the beam by about 1". Will check the 15 degree orientation logic more thoroughly, I can't find an easy way into the telescope near the plates. Apparently when you orient the plates at 15 degrees they move all the way in perpendicular to the beam then they each back out about 20 degrees then they move back in and stop at 7.5 degrees from perpendicular (hopefully). Found dust floating around inside the telescope, this is probably a big contributor to the "noisy sky problem", we will need to flush out the air, maybe by putting an air filter in the telescope and blowing the circulated air out the front hatches near the O1. The fan for the air circulation system wasn't working, I tightened the connection and it started up OK, took apart the connector for inspection but the wires were OK, the sleeves that fit over the pins on the other half of the connector are probably enlarged a bit. Sat Sep 24 23:05:09 GMT 1994: Patrol Start WEATHER COMMENT: Sat Sep 24 23:07:10 GMT 1994 Thick patches of cirrus moving into FOV. Orographic clouds also closing from South and West. COMMENT: Sat Sep 24 23:08:15 GMT 1994 ***************************************************** chu relieving koon as obsever ***************************************************** DPMON COMMENT: Sat Sep 24 23:14:33 GMT 1994 Dpmon appears to be domed out. Rotated dome and engaging ADR. Sat Sep 24 23:18:03 GMT 1994: Patrol End Sat Sep 24 23:21:58 GMT 1994: Patrol Start DPMON COMMENT: Sat Sep 24 23:22:19 GMT 1994 Diffuser apparently didn't reset earlier when we recycled the Plessey power. Stopped patrol to manually reset. Dpmon now operating normally. WEATHER COMMENT: Sat Sep 24 23:38:33 GMT 1994 Orographic clouds moving through FOV. Sun Sep 25 00:00:59 GMT 1994: Calibration COMMENT: Sun Sep 25 00:31:14 GMT 1994 Small orographic clouds have been moving in and out of FOV. Still patches of blue sky present. Will continue to run in hopes of getting good data in between clouds. Sun Sep 25 01:01:06 GMT 1994: Calibration COMMENT: Sun Sep 25 01:57:33 GMT 1994 Reconfigured the dome slot. Sun Sep 25 02:00:59 GMT 1994: Calibration WEATHER COMMENT: Sun Sep 25 02:34:31 GMT 1994 In a hole between receding orographic clouds, altocumulus which has passed to the East, and cirrostatus moving in from West. Sun Sep 25 03:01:01 GMT 1994: Calibration WEATHER COMMENT: Sun Sep 25 03:15:33 GMT 1994 Clouds have cleared FOV. Now in clear skies. Sun Sep 25 03:31:04 GMT 1994: Patrol End COMMENT: Sun Sep 25 03:31:19 GMT 1994 Have been under mostly cloudy skies during pm shift. Sky has only recently cleared up. Activity Report: QP: 97; 110; 215; 273. No Coronal Activity.
