First indication was airbrush compressor not running. It is usually sluggish when it is cold in the morning so its failure this morning did not raise any flags -- it was 27 degrees this morning. A3 breaker controls the outlets on the dome floor, east and middle on the south side of the pier. Also plugged into the east receptacle are the Meadowlark CHIP filter controller -- hence no temperature control,>> off-band images. Also plugged into east receptacle is the AC power to the Dalsa camera heater power supply (red cable). Lack of temperature control at the Dalsa camera may have caused the 5VDC power supply failure???? Middle receptacle controlled by the A3 breaker powered the dome phone and the David Clark sound powered headphones alert annunciator. ___end___ **CHIP PROBLEM**: Wed Jan 21 20:08:20 GMT 2009 Off-band performance will continue until the CHIP filter reaches the correct operating temperature and stabilizes. ___end___ **CHIP PROBLEM**: Wed Jan 21 21:35:42 GMT 2009 CHIP images are starting to look normal again, filter must be near or at correct temperature. ___end___ GONG COMMENT: Wed Jan 21 22:59:25 GMT 2009 Going down to GONG to make some requested measurements. ___end___ GONG COMMENT: Wed Jan 21 23:37:21 GMT 2009 Back from GONG ___end___ NICE PICSLIMB IMAGE: 2349 NICE PICSDISC IMAGE: 2348 NICE CHIP IMAGE: 2350 **PSPT PROBLEM**: Thu Jan 22 01:02:00 GMT 2009 C/k/r ___end___ Thu Jan 22 02:27:32 GMT 2009 CHIP End Patrol Thu Jan 22 02:28:24 GMT 2009 PICS End Patrol Thu Jan 22 02:37:23 GMT 2009 MkIV
