Will do a Kill/Run cycle to fix that and because David made a change that needs to be picked up that way. Thu Dec 20 19:26:38 GMT 2001 PICS Start Patrol **PICS PROBLEM**: Thu Dec 20 19:34:49 GMT 2001 David said they noticed Filter wheel wasn't turning according to their data. I've been too busy to work on this vignetting problem since it was first noticed again yesterday, so I just watched the Drive and Staus LEDs and can see that the Drive is happening but not the actual positioning. I hope to be able to get to this later. I'll probably need to replace a setscrew with a good capscrew to get it tightened enough to prevent future slipping. This is unrelated to the recent modification I made to fix the Home switching, that was to eliminate timeouts and probably didn't cause vignetting. Last week there was another vignetting problem and Eric found the Filter Wheel loose and tightened it, I had also tightened it a few months back, and it probably is loose again. I'll check in a while. **PSPT PROBLEM**: Thu Dec 20 19:44:36 GMT 2001 I looked up some information requested by Kim regarding temperature recording we did back in 11/98, I'll email it out soon. The images have been getting more fuzzy lately, I think this is due to the "optical gain", I checked and that telephoto lens adjustment and it had moved slightly, I adjusted it to the extreme position (CW looking down at front of lens, lens at longest position) where Roy had left it, then I taped it in place better. I may have to experiment with this later. That stopped some mirror oscillations that were occurring, but it is a tiny movement from that extreme position to a position taht causes fast-mirror oscillations. **MKIV PROBLEM**: Thu Dec 20 19:59:55 GMT 2001 This is still doing well after connecting a bench power supply to the 5 vdc power supply for the Barrel Angle Readout that I did yesterday.

Thu Dec 20 21:19:18 GMT 2001 PICS Start Patrol **PICS PROBLEM**: Thu Dec 20 21:23:12 GMT 2001 After I stopped the Patrol I tried moving the filter wheel using the GUI and it worked, so I started up Patrol and the Filter Wheel is moving properly now. So I'm going to leave this alone for now, I'll pull it apart and check it out another day. **GONG PROBLEM**: Thu Dec 20 21:27:30 GMT 2001 Heading down to shelter to work on some problems involving power supplies, breaker installation, and Waveplate motor tests. This instrument has been down since late Sunday.

This will allow them to ship us spare parts tomorrow instead of next week.
