Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sun Sep 11 16:57:26 GMT 1994 Year: 94 Doy: 254 Observer: chu WEATHER COMMENT: Sun Sep 11 16:57:31 GMT 1994 Thin layer of cirrus extending across the sky from East to West. Moderate wind from Southeast. Temp 42F. Humidity49%. Sun Sep 11 16:59:38 GMT 1994: Patrol Start MKIII COMMENT: Sun Sep 11 17:00:21 GMT 1994 Beginning obs with MKIII partially blocked by dome wall. Sun Sep 11 17:01:12 GMT 1994: Calibration MKIII COMMENT: Sun Sep 11 17:09:33 GMT 1994 MKIII has cleared dome wall. WEATHER COMMENT: Sun Sep 11 17:23:58 GMT 1994 Cirrus severely degrading both MKIII and Dpmon limb images. Sun Sep 11 18:02:56 GMT 1994: Calibration Sun Sep 11 19:03:01 GMT 1994: Calibration DPMON COMMENT: Sun Sep 11 19:11:27 GMT 1994 Configured Dpmon to disk preferred mode. DPMON COMMENT: Sun Sep 11 19:59:05 GMT 1994 Will leave Dpmon in disk preferred mode, since limb images continue to be washed out by cirrus. Sun Sep 11 20:02:57 GMT 1994: Calibration COMMENT: Sun Sep 11 20:46:28 GMT 1994 Dpmon domed out. Reconfigured the dome slot to correct. DPMON COMMENT: Sun Sep 11 20:47:00 GMT 1994 Reconfigured the Dpmon to limb preferred mode for hourly calibration. WEATHER COMMENT: Sun Sep 11 20:56:49 GMT 1994 In thinnest region of cirrus so far today. Dpmon limb images clearing a bit. Can make out a few prominences, but still quite fuzzy. MKIII scans still no good. Loaf of bread monitor still off the scale. Sun Sep 11 21:02:58 GMT 1994: Calibration WEATHER COMMENT: Sun Sep 11 21:18:33 GMT 1994 Cirrus thickening again. Dpmon limb image washout again. DPMON COMMENT: Sun Sep 11 21:44:19 GMT 1994 Dpmon doming out every few minutes due to tight fit in dome slot during this time of day. Rotated the dome and engaging ADR. WEATHER COMMENT: Sun Sep 11 21:49:27 GMT 1994 Patches of orographic clouds have moved upslope from West. May pass into FOV in a while. COMMENT: Sun Sep 11 22:02:28 GMT 1994 ADR doesn't seem to be working very well. Dpmon still doming out. Manually rotated dome to favor of Dpmon since MKIII scans still completely corrupted by cirrus. WEATHER COMMENT: Sun Sep 11 22:30:02 GMT 1994 Cirrus thinning a tiny bit. COMMENT: Sun Sep 11 22:56:37 GMT 1994 ADR seems to be working correctly now. Earlier problem was probably due to the empheris transit being more parallel with the dome slot than perpendicular.

Loaf of bread diagram was off scale during entire day. No good MKIII data. Will recycle tape. May have gotten a few good Dpmon images during mid-day. PAU.
