We had a couple recipe issues for the first couple passes but starting at 20:02:31, the data set contains flats with the ucomp diffuser, the 1" nd filter and the old comp diffusers. With the 1" filter in the beam we see a circle of light about the size of the occulter but offset form the occulter toward the edge of FOV. Perhaps the box of the front of the O1 isn't concentric with the O1. During this test I was worried the O1 the new O1 might have a tilt driving the image of the ND filter off the center of the detector (thinking about it now that the test is done I am less sure this makes sense). But the find_focus.cbk data 789 at various O1 postions was taken with ND filter in the beam to see if there was any beam walk. ___end___ Thu Nov 04 21:13:01 GMT 2021 Running UCOMP Cookbook 656_Pol_Calibrate.cbk line 0 UCoMP COMMENT BY berkey: Thu Nov 04 21:13:38 GMT 2021 At the end of the diffuser test I noticed the edge of the occulter in the "flats" which was also reported this morning by Steve. So post find_focus.cbk, some testing was done moving the occulter in and out of the beam while looking at flats (diffuser in the beam) in real time. Here we noticed that at the end of travel (-3.13mm) for the occulter stage the we no longer see the shadow of the occulter stage in the flats data. I don't understand what changed such over the weekend to cause the occulter to no longer completely level the beam. But we have at least temporarily solved the issue by now driving the Occulter stage to -3.13 mm when moving the occulter of the beam instead of the nominal home postilion of 0mm on the stage. ___end___ Thu Nov 04 21:17:05 GMT 2021 Running UCOMP Cookbook 789_Pol_Calibrate.cbk line 0 Thu Nov 04 21:21:08 GMT 2021 Running UCOMP Cookbook 1074_Pol_Calibrate.cbk line 0 Thu Nov 04 21:25:12 GMT 2021 Running UCOMP Cookbook 1079_Pol_Calibrate.cbk line 0 Thu Nov 04 21:29:16 GMT 2021 Running UCOMP Cookbook waves_1074_1hour.cbk line 0 Thu Nov 04 21:32:01 GMT 2021 UCoMP Paused for clouds GENERAL COMMENT BY berkey: Thu Nov 04 21:33:50 GMT 2021 Lost guiding when the dome controller clipped the egde of the shutter.

During this mornings fix of the occulter to move further out of range, the in position value was wrongly configured. During this time some disk light may have made it back to the modulator. ___end___ Thu Nov 04 23:49:55 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 7 Thu Nov 04 23:58:50 GMT 2021 UCoMP Paused for clouds Fri Nov 05 00:07:42 GMT 2021 UCoMP Restarted from pause UCoMP COMMENT BY berkey: Fri Nov 05 00:08:41 GMT 2021 The o1 motor had a hiccup and needed resetting. ___end___ ONSITE STAFF: berkey
