Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sun Sep 24 16:50:29 GMT 1995 Year: 95 Doy: 267 Observer: yasukawa console Sep 24 16:48 WEATHER COMMENT: Sun Sep 24 16:50:47 GMT 1995 Cool, clear, brisk south wind. Cirrus bands to east and west, a few patches to south. MKIII COMMENT: Sun Sep 24 16:51:26 GMT 1995 Swapped A and B inputs to microprocessor, swapped phase settings--input A to delay setting #B to #5 and the input B setting from #5 to #B. This was done to see if I dropout occurs in chan 1 data due to swap. This will tell us if the dropouts are occurring ahead or beyond the micro. Sun Sep 24 17:02:03 GMT 1995: Patrol Start MKIII COMMENT: Sun Sep 24 17:08:00 GMT 1995 Checking phasing of channels to make sure phase swap is appropriate. MKIII COMMENT: Sun Sep 24 17:13:46 GMT 1995 Intuitive swap of phasing was incorrect. Checked and adjusted phasing with opal and 15 tilt. Both micro channels phased at setting #8 to get peaks at 0 and 180 degrees. MKIII COMMENT: Sun Sep 24 17:20:24 GMT 1995 Orientation of coronal image on 1 CHAN CORONA is rotated, may not be able to get around that on for now. Will insert opal and tilt plate to confirm phasing again. I dropout will show up if it is going to happen regardless that I am not taking coronal data, so long as the data is going to tape. MKIII COMMENT: Sun Sep 24 17:27:50 GMT 1995 Taking opal and tiltplate out, resuming swapped coronal scans in hopes that we will capture an I dropout. I plan to run like this until around 1800 UT and then I will swap the inputs and phasing back. I'll probably have to begin a new tape as stopping the micro will cause the tape to halt and rewind. I'll do a WEEP, 0EOF and 0BACK before turning off micro to swap input connectors. DPMON COMMENT: Sun Sep 24 17:39:56 GMT 1995 Optics runaway. Resetting.

Should not affect I-drop hunt but ruined coronal data. MKIII COMMENT: Sun Sep 24 18:17:29 GMT 1995 Stopped tape, doing 0EOF and 0BACK and turning off micro to swap inputs and reset nominal phasing of B for input A and 5 for input B. MKIII COMMENT: Sun Sep 24 18:30:23 GMT 1995 Turning off micro does halt the PDP-11. Rebooting it rewinds the tape so I did have to remove H01124 and load H01125. Checked phasing and they look OK. Resuming coronal observations. Sun Sep 24 19:03:02 GMT 1995: Calibration COMMENT: Sun Sep 24 19:49:16 GMT 1995 Opening top of dome.
