Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Thu Jan 19 17:29:49 GMT 1995 Year: 95 Doy: 019 Observer: yasukawa WEATHER COMMENT: Thu Jan 19 17:30:32 GMT 1995 Cool, clear, southeast wind, temp=42F. Thu Jan 19 17:37:33 GMT 1995: Patrol Start MKIII COMMENT: Thu Jan 19 17:44:29 GMT 1995 Camera Busy failure. Invoked Clearbusy to clear the problem. Thu Jan 19 18:00:59 GMT 1995: Calibration MKIII COMMENT: Thu Jan 19 18:36:54 GMT 1995 Sky or instrumental polarization has increased, maybe due to alignment changes made yesterday, which would explain some of the decreased intensity seen in vdiffs between pre and post alignment coronal images. MKIII COMMENT: Thu Jan 19 18:47:00 GMT 1995 Stopped MKIII. Will continue alignment attempt. Yesterday's effort made things worse in my opinion.

MKIII COMMENT: Thu Jan 19 21:24:15 GMT 1995 Adjusted things back as close to where it was before. Could not make changes that seemed to improve the coronal signal. Will await engineering expedition to try some other techniques.
