Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Fri Jun 10 17:17:16 GMT 1994 Year: 94 Doy: 161 Observer: koon COMMENT: Fri Jun 10 17:18:13 GMT 1994 Still in medium cirrostratus, will wait until it clears before observing. Wind ~5 mph from the south, temp ~50 F. LOW-L COMMENT: Fri Jun 10 17:19:42 GMT 1994 Removed L00057 and installed L00058 in drive #0, restarted program. Fri Jun 10 18:29:11 GMT 1994: Patrol Start COMMENT: Fri Jun 10 18:29:16 GMT 1994 Wind has shifted and is now ~5 mph from the north, cirrostratus has thinned enough to start taking data, it is blowing over from the west. DPMON COMMENT: Fri Jun 10 18:32:13 GMT 1994 Current exposure times for the limb and disk are set to 120 ms. O2B focus is at 3.54 mm to get some initial disk images, I will change this later to get better limb images. Using 0.8" Lyot stop w/ hr filter. DPMON COMMENT: Fri Jun 10 18:35:48 GMT 1994 Daystar filter was moving in and out of light path, I will reset Plessey and manually reset the filter position. End Fri Jun 10 18:38:03 GMT 1994: Patrol Start DPMON COMMENT: Fri Jun 10 18:48:34 GMT 1994 I have changed the O2B mike to 4.7 mm for better limb focus. DPMON COMMENT: Fri Jun 10 18:53:47 GMT 1994 Nice prominence coming around the east limb. The occulting disk is too big so I will pause Patrol and install the best disk. Fri Jun 10 19:10:49 GMT 1994: Patrol Start DPMON COMMENT: Fri Jun 10 19:11:02 GMT 1994 Changed to a 1931 arcsecond diameter occulting disk, restarted Patrol. DPMON COMMENT: Fri Jun 10 19:26:35 GMT 1994 Thin cirrus preventing me from doing limb focus testing, maybe later. MKIII COMMENT: Fri Jun 10 19:27:26 GMT 1994 Thin cirrus preventing me from getting any calibrations. MKIII COMMENT: Fri Jun 10 19:48:48 GMT 1994 In clear sky now, taking 0 chan calibration. Fri Jun 10 20:02:14 GMT 1994: Filemark-Calibration COMMENT: Fri Jun 10 20:18:14 GMT 1994 Extended the dome slot. DPMON COMMENT: Fri Jun 10 20:19:04 GMT 1994 Will pause the Patrol to do some manual limb image focus testing. Fri Jun 10 20:20:15 GMT 1994: Patrol End DPMON COMMENT: Fri Jun 10 20:23:21 GMT 1994 Program crashed and I lost the Focus and Display windows, core was dumped to my directory and /opt got 100% filled. Will delete core file and logout/login to see if this will correct problem. DPMON COMMENT: Fri Jun 10 20:41:25 GMT 1994 Had to reboot, couldn't logout. Did an "End Day" and loaded a new tape (P00078) before rebooting. DPMON COMMENT: Fri Jun 10 20:51:20 GMT 1994 Crashed with the "Camera:Busy" message, rebooting. DPMON COMMENT: Fri Jun 10 22:04:20 GMT 1994 The Weather cooperated and I was able to get all the focus test images. Saved images of the limb w/ O2B at 4.7, 4.8, 4.9, 5.0, and 5.1 mm. Also saved an image of the disk w/o the hr filter and w/ 0.7" paper Lyot stop and exposure at 50 ms., and saved a disk image w/ hr filter, 0.7" paper Lyot stop and exposure of 140 ms for comparison. The image w/o the hr filter is sharper if you look at the active region w/ the two small sunspots (in the northeast). Will stop observing for today now. MKIII COMMENT: Fri Jun 10 22:09:21 GMT 1994 Doing dark scan now. COMMENT: Fri Jun 10 22:13:35 GMT 1994 Activity report: QP: 70-95; 305. No coronal activity. TAPES: MKIII: H00772 DPMON: P00077 LOW-L: L00057 removed in morning, L00058 installed and running. SAN-LOG SAN-LOG ?
