Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sat Apr 30 17:08:38 GMT 1994 Year: 94 Doy: 120 Observer: yasukawa COMMENT: Sat Apr 30 17:08:53 GMT 1994 In broken altocumulus and thin cirrus, remote chance of clearing later in the day. Southeast wind, temp = 50 degrees F. Low-L running OK this morning. Tape L00033 ejected from unit 0, Tape L00034 running in unit 1. Loaded tape L00035 in unit 0. Checked time display on Low-L with WWVH at Barking Sands, Kauai, (1-335-4363), it is right on. DPMON COMMENT: Sat Apr 30 17:21:32 GMT 1994 Aperture wheel was running, rebooted Plessey, moved wheel back to clear station in manual mode, tested other optical systems. MKIII COMMENT: Sat Apr 30 17:23:47 GMT 1994 Running a couple of dark scans, then will stop tape and wait for clear sky to resume taking data. COMMENT: Sat Apr 30 18:45:37 GMT 1994 Opened up dome (with top open), as cirrus is thinning and altocumulus is more scattered. Standing by. Sat Apr 30 18:53:30 GMT 1994: Patrol Start MKIII COMMENT: Sat Apr 30 18:54:15 GMT 1994 Starting coronal scans. Sat Apr 30 19:00:19 GMT 1994: Filemark-Calibration MKIII COMMENT: Sat Apr 30 19:38:12 GMT 1994 Clouds tainted calibration. Sat Apr 30 20:00:19 GMT 1994: Filemark-Calibration COMMENT: Sat Apr 30 20:17:05 GMT 1994 Checking thru past data, DOY 94109 looked as if corona file saved in HISTORY was no good--taken in cirrus. Removed it from HISTORY database, changed dot calendar to reflect the removal with an "N" in the yellow dot. DPMON COMMENT: Sat Apr 30 20:21:10 GMT 1994 Halle runaway. rebooting Plessey and restarting Patrol. Aperture was crashed too. resetting it. Sat Apr 30 20:24:20 GMT 1994: Patrol End Sat Apr 30 20:25:40 GMT 1994: Patrol Start COMMENT: Sat Apr 30 20:36:07 GMT 1994 Sparcstation time (and MKIII time, as I set 11/44 time by the Sparcstation clock display) is 6 seconds behind WWVH time-check. This comment is logged long after the timecheck was done because I was looking thru the manuals for a way to change the clock in the meantime. Apparently it takes a superuser to make the change. Sat Apr 30 21:02:20 GMT 1994: Filemark-Calibration COMMENT: Sat Apr 30 21:12:27 GMT 1994 $$$ sky quite noisy now. Cirrostratus and orographic clouds are forming overhead. COMMENT: Sat Apr 30 21:14:27 GMT 1994 $$$ in the clouds now. beginning shutdown process.
