**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.

**PSPT PROBLEM**: Thu May 20 21:18:11 GMT 1999
OK, I fixed the problem and I'm taking data again.  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.

**PSPT PROBLEM**: Thu May 20 22:36:57 GMT 1999
The noontime images are starting to get vignetted by the dome due to the 
path of the sun this time of year (in Hawaii) and the way the dome is 
pointed by software.  We will need to at least comment out the auto
pointing software routine and point the dome manually for a few months.
