Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sun Mar 20 17:53:19 GMT 1994 Year: 94 Doy: 079 Observer: koon COMMENT: Sun Mar 20 17:54:05 GMT 1994 Cool, Clear sky, light wind from the southeast. DPMON COMMENT: Sun Mar 20 17:54:53 GMT 1994 Can't control the Bench Angle from the control room interface. I can move it manually from upstairs and the clock drive appears to be working, but the angle readout doesn't match the actual position. Sun Mar 20 18:06:31 GMT 1994: Patrol Start DPMON COMMENT: Sun Mar 20 18:06:36 GMT 1994 Bench was upside down, I manually slewed it to approximately correct position and then the manual "control room" controls worked OK. Not sure why the bench was in that position or why it doesn't work properly from that position but normally this isn't an initial starting position. Sun Mar 20 18:18:02 GMT 1994: Patrol End DPMON COMMENT: Sun Mar 20 18:30:37 GMT 1994 Noticed that the disk images were very overexposed, stopped Patrol and manually tested exposure times. The disk looked featureless indicating a possible filter problem. Went upstairs and felt the Daystar filter, it was cold. Couldn't find any problem with wiring, unplugged filter and tested the circuit it was on, circuit was good so I plugged the filter back in and it started to get warm, possble flaky extension cord plug, will replace it.

DPMON COMMENT: Sun Mar 20 19:31:17 GMT 1994 Having problems with the Daystar filter again, it went cold.

Can feel heat at control box so electricity is getting that far. Opened box but didn't see any broken wires or burnt parts. Pulled entire filter out and will test it at bench. taped over the filter aperture and set disk exposures way down to 1/100 of a second so that the patrol program can be used for limb observations while we work on the filter (I wasn't sure if I could set the exposure to 0 w/o crashing the program). Will contact the Daystar company for schematics if necessary during the week. dsgt Sun Mar 20 21:43:24 GMT 1994: Patrol Start Sun Mar 20 21:49:06 GMT 1994: Patrol End COMMENT: Sun Mar 20 21:49:33 GMT 1994 Activity Report: QP: 97; 120; 235; 272.
