Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sun Aug 28 16:39:14 GMT 1994 Year: 94 Doy: 240 Observer: chu WEATHER COMMENT: Sun Aug 28 16:39:34 GMT 1994 Thin but extensive cirrostratus cloud cover. Cold, temp 39F. Humidity 53%. Light wind from South. Sun Aug 28 16:40:51 GMT 1994: Patrol Start MKIII COMMENT: Sun Aug 28 16:44:48 GMT 1994 Beginning day with MKIII partially domed out. WEATHER COMMENT: Sun Aug 28 16:50:36 GMT 1994 In thin cirrostratus, enough to wash out MKIII and Dpmon images. Will continue to run in hopes of obtaining data in any holes which appear. Sun Aug 28 17:02:04 GMT 1994: Calibration COMMENT: Sun Aug 28 17:21:39 GMT 1994 Guider went into high frequency oscillation. Recycled power to correct. Sun Aug 28 18:02:00 GMT 1994: Calibration Sun Aug 28 19:01:59 GMT 1994: Calibration Sun Aug 28 20:02:00 GMT 1994: Calibration COMMENT: Sun Aug 28 20:35:41 GMT 1994 Reconfigured the dome slot, and continuuing cirrus vigil. Sun Aug 28 21:02:03 GMT 1994: Calibration WEATHER COMMENT: Sun Aug 28 21:16:25 GMT 1994 Appears to be in a hole in cirrus. P-S monitors show that there is still some cirrus interfering with MKIII data. MKIII COMMENT: Sun Aug 28 21:20:35 GMT 1994 Still too much interference to be able to get a good coronal scan. "1take" looks like cirrus degraded noise. WEATHER COMMENT: Sun Aug 28 21:23:23 GMT 1994 Orographic clouds closing in from West. Will pass into FOV in a minute. Sun Aug 28 22:01:59 GMT 1994: Calibration WEATHER COMMENT: Sun Aug 28 22:29:00 GMT 1994 In broken orographic clouds. Cirrus seen within holes above orographic clouds Sun Aug 28 23:02:03 GMT 1994: Calibration WEATHER COMMENT: Sun Aug 28 23:37:26 GMT 1994 In complete orographic overcast. Sun Aug 28 23:47:02 GMT 1994: Patrol End COMMENT: Sun Aug 28 23:47:05 GMT 1994 Closing dome to avoid moisture from low level fog. COMMENT: Mon Aug 29 00:29:55 GMT 1994 Have been completely clouded over, will remain so for remainder of day. No good coronal scans out of ~120 taken. Will recycle tape. Brief periods of good viewing for Dpmon around 22:00UT. Activity Report: QP: 78; 90-92; 246; 269. No Coronal Observations. Tapes: MKIII: recycled DPMON: P00145. LOW-L: L00099 running in unit 0.
