**MKIV PROBLEM**: Thu Jul 15 17:44:31 GMT 1999
Scoured MKIII/IV looking for possible sources of light leaks.
Found foil tape covering some of the trough cavities with pukas (holes) 
to the interior not securely sealing in places.  Resealed tape or replaced
tape.  Also found several places where light may have been finding its
way inside the MKIII/IV, sealed them up with foil tape.
**MKIV PROBLEM**: Thu Jul 15 17:49:42 GMT 1999
Stopping MKIV to reboot KCC, then running a CORRECT.
Barrel ran to a hardware limit after the KCC reset.

Rebooting KCC.
MKIV COMMENT: Thu Jul 15 18:35:06 GMT 1999
Barrel running back to CW software limit (I hope) after KCC reset.
MKIV COMMENT: Thu Jul 15 18:36:38 GMT 1999
Barrel stopped at CW software limit (phew!).  Running another CORRECT.
Thu Jul 15 18:37:18 GMT 1999    MKIV    Start Correct
MKIV COMMENT: Thu Jul 15 18:37:55 GMT 1999
Dark correct listing out values we are looking for, 0s and -1s.
MKIV COMMENT: Thu Jul 15 18:38:45 GMT 1999
Correct pau.  Running Calibration.
Thu Jul 15 18:39:09 GMT 1999    MKIV    Start Cal
**MKIV PROBLEM**: Thu Jul 15 18:39:50 GMT 1999
t_disp crashed again. Calibration is "running" but nothing is being displayed.
Data are not being written to disk, also, at the end of the Cal scan,
this happened both cal attempts.  Due to t_disp crash?
**MKIV PROBLEM**: Thu Jul 15 18:54:49 GMT 1999
Rebooting KCC.  Starting calibration as soon as KCC is ready.
Thu Jul 15 18:59:20 GMT 1999    MKIV    Start Cal
MKIV COMMENT: Thu Jul 15 18:59:46 GMT 1999
Calibration started up OK this time, display task is running OK.
Problem could be happening at the end of the Correct or with some
interaction between correct and calibration???

**** EVENT COMMENT ****: Thu Jul 15 19:15:26 GMT 1999
I think there was an EPL on the southwest limb while I was tending to 
MKIV problems.  EPL gone now.  Appears to be an active region on 
northeast limb too.
