Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sat Aug 6 16:39:33 GMT 1994 Year: 94 Doy: 218 Observer: koon WEATHER COMMENT: Sat Aug 6 16:39:38 GMT 1994 Clear, wind ~10 mph from the southeast, temp ~50 F. LOW-L COMMENT: Sat Aug 6 16:59:39 GMT 1994 Unloaded L00088 from drive #0 and loaded L00090. DPMON COMMENT: Sat Aug 6 17:00:15 GMT 1994 I'm trying to get a "Camera:Busy" crash so I can test the new recovery procedure. Sat Aug 6 17:01:47 GMT 1994: Patrol Start Sat Aug 6 17:13:02 GMT 1994: Patrol End Sat Aug 6 17:14:26 GMT 1994: Patrol Start DPMON COMMENT: Sat Aug 6 17:38:34 GMT 1994 I was able to get a "Camera:Busy" crash, using David's recovery procedure works great! It basically kills the task "Camera" then starts it again and redirects screen output to /dev/null, then loads an exposure of 1 (it probably had a value of 255 which means it was busy therefore the Patrol program wouldn`t continue). I tried this before without killing the Camera task but it didn`t work. Now we can continue writing to the same tape afterr the infamous "Camera:Busy" crashes. MKIII COMMENT: Sat Aug 6 17:45:30 GMT 1994 Doing a calibration of channel 0. DPMON COMMENT: Sat Aug 6 17:45:51 GMT 1994 Since the weather is nice I'll start focusing the O2A unless some solar activity is detected.

Switched to optimum disk image setup:0.7" LS, 3.85 mm, exp=50 ms. Sat Aug 6 19:02:21 GMT 1994: Calibration Sat Aug 6 19:07:00 GMT 1994: Patrol End DPMON COMMENT: Sat Aug 6 19:07:06 GMT 1994 Exposure switched back to 120 ms. Will now try focusing the O2A and O2B.

It was very difficult to see a converging pattern for the disk and limb focus. Duc helped me when he got up here but the seeing got bad and clouds moved in, we'll have to try again earlier in the day with two people. Have returned O2A and O2B back to initial positions in order to continue data taking. WEATHER COMMENT: Sun Aug 7 00:30:43 GMT 1994 Will be in and out of orographic clouds on the western horizon for the remainder of the day.

Will end patrol and wait for clearing. COMMENT: Sun Aug 7 01:48:40 GMT 1994 Reconfigured the dome slot, and continuing to wait for a clearing. COMMENT: Sun Aug 7 02:27:02 GMT 1994 Doesn't look like we will get any more decent images for the day. Will close down.
