COMMENT: Fri May 26 16:50:04 GMT 2000 Net back up. **PSPT PROBLEM**: Fri May 26 17:28:18 GMT 2000 Tried pspt startup. Bacground workspace still up from yesterday. Startup ran OK although dark frame looked very dark. Spar was not pointing to sun when done, it was about 10 degrees south. Pointed manually using shadows. Center image program failed. Kept trying to get an image but failed due to low intensity. I could not hear the shutter consistently, but that could be due to the ambient noise. Program finally stalled completely. Last message on xterm was: % Internal error: Unable to set timer Argument out of domain C is acknowledged ("interrupt encountered") but not acted upon. Shutdown PSPT manually. Rebooted sparc. Did an init sys on PC. **PSPT PROBLEM**: Fri May 26 17:35:52 GMT 2000 Startup proceeded with no problem except there was no blue image on the gui when it was done. Spar was pointed correctly. We may be having a shutter failure, among other things. There is no spare shutter in our inventory at this time. Have not received any spares back from Boulder yet. **PSPT PROBLEM**: Fri May 26 17:43:27 GMT 2000 Daily Obs program failed. Looks like it could not get an image. I did not hear the shutter clicking. I will check out shutter. Exited IDL. **PSPT PROBLEM**: Fri May 26 17:51:34 GMT 2000 Removed shutter and tested it with driver. Shutter has failed. one leaf is completely stuck. I will alert Randy.

PICS COMMENT: Fri May 26 19:19:04 GMT 2000 stopping PICS too, clouds too thick, disc image dark. CHIP COMMENT: Fri May 26 19:20:01 GMT 2000 CHIP image is bad, too.

Fri May 26 19:23:31 GMT 2000 CHIP CHIP End Patrol Fri May 26 20:24:03 GMT 2000 CHIP ending tape WEATHER COMMENT: Fri May 26 20:24:27 GMT 2000 Overcast is now thick and extensive. Shutting down. LOW-L COMMENT: Fri May 26 20:24:59 GMT 2000 LOWL electronics bay was only screwed down with a few screws due to the many iterations at closing in on the best temperature settings. Tightened down all the screws as the weather may be changing for the worse. Tomczyk may be close to correct setting in any case.
