Looks like sky might be a little too bright. ___end___ KCOR COMMENT BY berkey: Thu Apr 29 01:51:45 GMT 2021 No kcor data today. Cirrus never broke. ___end___ UCoMP COMMENT BY berkey: Thu Apr 29 02:06:25 GMT 2021 Between ticker cirrus clouds there was an attempt to align UCoMP. Using the kenamtic adjusters the the instrument plate was adjusted to give the best alignmed possible on the field lens target. This alignment seemed to be robust against O1 moves front to back. Image also looked well centered on the modulator iris. The alignment was not perfect on the cameras image; but solar was less than 50 pixels from the centered of the detector. With motion of <20 pixels across the O1 (0-62mm) focus range. Overall most of this work was hampered due to constant changing cloud cover. With semi-thick cirrus a dry run was done on measuring the wavelength offsets. This is probably not valuable data due to the cirrus and the strong likelyhood we will continue the align the instrument, but it gave the chance to debug some of the recipes. At the end of the day the airforce target was installed for a few images to a check for how well the current alignment is. This data was taken at 1083. There was a mistake in the way the recipe was written so the fits file containing this data has both darks and airforce flats. After a quick look at the data I dont think our alignment is there yet. ___end___ ONSITE STAFF: berkey
