Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Fri Mar 15 17:18:11 GMT 1996 Year: 96 Doy: 075 Observer: koon console Mar 15 17:15 WEATHER COMMENT: Fri Mar 15 17:18:15 GMT 1996 Clear sky, wind=10 mph from the SE, temp=35 F. Fri Mar 15 17:22:07 GMT 1996: Patrol Start MKIII COMMENT: Fri Mar 15 18:00:39 GMT 1996 Having problems, data not being written to tape, error messages with incorrect dates and times in the scan-log. Tried stopping scans, cycling power to the tape drive, and rerunning setup then restarting observing, no difference. Then tried shutting down the computer and bringing everything back up from scratch, still having same problem. At the beginning of each scan the orange light on the drive stays on for a while as if something in the drive is preventing the writing of data. DPMON COMMENT: Fri Mar 15 18:18:31 GMT 1996 Had an optical runaway about 10 minutes ago, fixed it but didn't log it then because I was logging the last MKIII entry at the time. MKIII COMMENT: Fri Mar 15 18:51:04 GMT 1996 Tried restarting with a diferent tape, same problem. Tried restarting after cleaning the tape drive, this appears to have fixed the problem, it looks like data is being saved now. DPMON COMMENT: Fri Mar 15 18:52:15 GMT 1996 Optical runaway, fixing it.
