The facility personal have begun working on the various areas of upgrade. ___end___ WEATHER COMMENT: mcotter: Tue Mar 01 21:34:35 GMT 2022 Temp: 53.1f, Humidity: 24%, Pressure: 28.74in, Wind: 11mph from 334degs, Skies: So far the skies remain clear in all directions.

My last few days working I have observed, at times, the light being more pronounced and brighter on one side of the occulter than the other. When speaking with Ben about this phenomenon Ben said that by adjusting the "Threshold" level for the SPAR the concentricity of the corona light around the occulter may be improved. This is because the actual light intensity increases during the course of the day. When I started out this morning the SGS threshold level was set to 10000. At mid morning, approximately 10:00 am HST I increased the threshold to15000. At approximately 11:30 am HST I again increased the threshold level to 20000. Again Ben went through the process with me on how the values are calculated and how the "Offsets", "Threshold" levels and "Saturation" levels are applied. Ben also pulled up an image of the Ucomp-Threshold level coronal images showing the brightest pixels levels displayed. Using this image we discussed the optimum intensity levels and how they vary. So far with the Threshold level set at 20000 the pixels saturation levels and concentricity appears to be aligned and stable. *NOTE*: The Threshold level and the Saturation level should be set to the same value. Max Saturation value: 100000. ___end___ Tue Mar 01 23:02:01 GMT 2022 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 0 Tue Mar 01 23:15:00 GMT 2022 UCoMP Paused for clouds WEATHER COMMENT: mcotter: Tue Mar 01 23:18:01 GMT 2022 Aerosols are increasing greatly and some small wisps of Cirrus clouds are beginning to form and pass through the viewing area. Both instruments are currently paused due to sky conditions. ___end___ Tue Mar 01 23:21:42 GMT 2022 UCoMP Restarted from pause WEATHER COMMENT: mcotter: Tue Mar 01 23:25:16 GMT 2022 Aerosols are high but I have restarted the Kcor instrument and so far the images look acceptable. Kcor and Ucomp again up and running. ___end___ Tue Mar 01 23:32:06 GMT 2022 UCoMP Paused for clouds WEATHER COMMENT: mcotter: Tue Mar 01 23:35:20 GMT 2022 Aerosols are increasing greatly and the images are beginning to look washed out. Additionally, Cirrus clouds are beginning to become more prevalent and are now scattered over the observatory and viewing area. ___end___ KCOR COMMENT BY mcotter: Tue Mar 01 23:35:49 GMT 2022 Kcor has been stopped due to sky conditions. ___end___ UCoMP COMMENT BY mcotter: Tue Mar 01 23:36:13 GMT 2022 Ucomp has been paused due to sky conditions. ___end___ Wed Mar 02 00:38:39 GMT 2022 UCoMP Restarted from pause Wed Mar 02 00:46:57 GMT 2022 UCoMP Paused for clouds GENERAL COMMENT BY mcotter: Wed Mar 02 02:17:14 GMT 2022 PM Blew off Kcor O1. Looking at the nrgf images there is a new large bullet hole in the NE that appears to move NW over time. O1 inspection showed a poorly attached piece of maybe be cotton fibers about 2" from the west edge of the O1. It is unclear if this is the source of the large bullet hole; and if it was the source if it had moved since we were were pointing at the sun imagine the big bullet hole. ___end___ ONSITE STAFF: berkey, mcotter, ucar facilities: rebecca,mark,gordon
