Tue Mar 23 17:14:52 GMT 1999 CHIP Startup--Initializing new tape **LOW-L PROBLEM**: Tue Mar 23 17:16:07 GMT 1999 LOWL crashed "overnight". Found waiting on DOS screen with L00587 popped out as it probably should have. Cleaned drive 0 and did the tape shuffle. L00588 in drive 0 and L00589 in drive 1. Set date and time and restarted with "lowl" command.

Checked controller and it is on. Coolant level was a tad low so we filled it to correct level.

CHIP is probably going through the hunting phase, before the temperature stabilizes.

I'll be removing the PICS covers so I may jostle the spar around while doing this. Tue Mar 23 18:48:36 GMT 1999 PICS End Patrol **CHIP PROBLEM**: Tue Mar 23 18:49:41 GMT 1999 CHIP filter temp keeps rising, I will try resetting the controller and will check that the circulator is circulating fluid.

Shutting CHIP down and turning controller off until I can determine what is wrong. PICS COMMENT: Tue Mar 23 20:47:38 GMT 1999 Remounted 1000 angstrom prefilter in the correct place. It needed to go just under (ahead of) theexisting 70 angstrom prefilter. PICS COMMENT: Tue Mar 23 20:51:04 GMT 1999 Setting up for Halle test.

A couple of the test positions went through the observing loop twice, so there will be two disk images for these positions.

With temp controller turned off, Temp was 28.7, resistance was 8.39 kilohms which is very close to listed resistance on spec sheet. Turned controller back on for the night. If temperature is too high or unstable tomorrow, Randy will stand down on CHIP. PSPT COMMENT: Tue Mar 23 22:47:50 GMT 1999 Randy set cadence to 30 min for PSPT today. Initial startup was at normal 1 hr cadence, took initial FF sequence and obs. Ended program, changed cadence, and restarted - hung PSPT and dome got lost. Re-booted sparc and PC - system ran fine after this. Around noon, pspt lost track of the sun. Did not try to re-start, shutting down.
