----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sat Oct 3 17:09:49 GMT 1998 Year: 98 Doy: 276 Observer: koon WEATHER COMMENT: Sat Oct 3 17:10:14 GMT 1998 Clear sky, wind=5 mph from the SE, temp=49 F. Sat Oct 3 17:11:10 GMT 1998 CHIP Startup--Initializing new tape Sat Oct 3 17:16:41 GMT 1998 PICS Start Patrol PSPT COMMENT: Sat Oct 3 17:48:19 GMT 1998 Judging from the email and logs it looks like we'll need to replace the mirror drive board as originally suspected, and that we can get some data in the meantime, so I started up the instrument. CHIP COMMENT: Sat Oct 3 17:49:59 GMT 1998 The filter temperature is still not regulating properly, the controller is turned off to prevent damage to the filter. I'm not sure what needs to be done next so I won't observe with CHIP until I can go through the email messages more carefully.

CHIP COMMENT: Sat Oct 3 22:35:45 GMT 1998 I removed the CHIP covers and checked the filter temperature sensor connections and cables. The cables are good physically and electrically, but the connection at the filter is flaky, resistance through the cable changed when I wiggled that connection. The connection at the temperature controller uses the same kind of connectors and it isn't flaky when wiggled. I'm not sure if this is the cause of the temperature problems we are having, but it makes sense that increased resistance through that cable could cause the controller to think the filter is too cold and therefore drive the filter temperature high. I'm leaving the covers loosely installed for insulation and so I can easily remove then tomorrow when I'll continue testing. I left the controller off all day and it will remain off overnight also.
