LOW-L COMMENT: Sat Jun 17 19:15:57 GMT 1995
Program crashed yesterday 6/16 01:20:56 ut while writing data to drive #0
on L00261.  Slight drop in phase voltage from 118.0 v to 117.8 v at about
the same time as the crash.  Instrument head was stowed.  Data writing 
switched from drive #1 to drive #0 mid-day yesterday, well before crash.
Removed L00260 from drive #1 and installed L00263, removed L00261 from
drive #0 and installed L00262.  Will get the West data requested by Steve
and then reset the computer to restart the program.

DPMON COMMENT: Sat Jun 17 23:05:20 GMT 1995
Instrument was progressively blocked by the dome for the last 30 minutes due
to the problem trying to get all instruments to see the sun this time of day
and year.

MKIII COMMENT: Sun Jun 18 00:05:19 GMT 1995
Data has been very noisy this afternoon, difficult to see any changes.


LOW-L COMMENT: Sun Jun 18 00:55:00 GMT 1995
Had six crashes between 2018 and 2214.  Chart voltage dipped below 116v 
during that period, after voltage got above 116v there were no crashes.  No
obvious surges noticed during that period, the heater/fan was very inactive
during that time also.  The 486 didn't crash although connected to the
lowl power strip.  Cycling the power to the computer and the tape drives
didn't stop the crashes.  Something odd, when I tried to eject the tapes
while starting up the lowl program they would rewind and stop without 
ejecting, then data would be written to the tape in drive #0.  Maybe this
is why the tape in drive #1 didn't eject yesterday when data suddenly
started to be written to drive #0 in the middle of the day.  I tried the
manual eject button as we always do, on the front of the drive by the door.
I recycled the tapes after each crash.
