----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Thu May 20 16:53:46 GMT 1999 Year: 99 Doy: 140 Observer: koon WEATHER COMMENT: Thu May 20 16:53:59 GMT 1999 Clear sky, wind=15 mph from the South, temp=40 F. rol Thu May 20 16:56:34 GMT 1999 PICS Start Patrol Thu May 20 17:00:28 GMT 1999 PICS Flat Thu May 20 17:01:32 GMT 1999 PICS End Flat **LOW-L PROBLEM**: Thu May 20 17:42:59 GMT 1999 Tape L00599 was popped out of drive #0 as it should have been, but the computer screen showed a DOS prompt and the observing program wasn't running. This has been happenning regularly lately, at least on the switch from drive #0 to drive #1. We know that data will go to drive #1 so this switching problem appears to be software related. I removed L00599 from drive #0 and left L00600 in drive #1 and put L00601 in drive #0. Then I restarted with data going to drive #1, we'll see if the change from drive #1 to drive #0 goes more smoothely.

The root of the problems was that the declination limit switch was being tripped at the positive limit. This prevented the fast miiror from locking in on the sun and also caused some strange pointing related problems because ephmcals were run without the declination axis being involved. A new Dec limit ring with the correct declination range is being mailed to us by Roy, so hopefully we won't bump into this problem again.

We will need to at least comment out the auto pointing software routine and point the dome manually for a few months.
