The inversion layer is visible on the horizon at approximately the level of Maunakea or higher, so I don't think the brightness of the Kcor Synoptic image is going to improve very much. ___end___ GENERAL COMMENT BY berkey: Mon Mar 22 21:13:40 GMT 2021 Kcor has been stopped. Altocumulus clouds have moved in from the east-northeast. Clouds are increasing to the south and appear to moving toward the observatory. ___end___ GENERAL COMMENT BY berkey: Mon Mar 22 21:15:41 GMT 2021 With the halting of the Kcor instrument we are beginning modification work to the spar extender to accommodate for additional movement we need to impart on Ucomp 01. ___end___ UCoMP COMMENT BY berkey: Tue Mar 23 01:42:24 GMT 2021 Spar extender mounting holes were enlarged from 3/8" 5/8" to accommodate a UCoMP O1 alignment. The spar extender was reinstalled keeping the North and south faces of-the spar extender as close to parallel to the spar as possible, and East-west the spar extender was moved below the spar by about 1/8" on the Chromag face. This change will force Chromag to use spacers or shims under the foreoptics to bring them back up to the level of the spar, previous investigations had found the spar extender was not square to the spar so we already knew shims would be required this change just forces larger spacers during the install. During the O1 assembly re-installation we found some cable damage on the O1 drive motor. The CD-0025B Orange +V cable had broke next to the motor side connection. The cable was brought down stairs and pin 2 was pushed out of the PADP-12V-1S connector, the broken wire was then soldered back onto the pin and finally the pin and wire were reinstalled into the connector. Post installation testings shows all 3 stages associated with the O1 (focus, cover and diffuser) are working nominally. New alignment range of the O1 could not be verified or tested due to clouds/rain/hail. Dome ADR sensors were reinstalled on the spar extender, they they likely will need some tweaking later in the week when we have sunshine. ___end___ WEATHER COMMENT: berkey: Tue Mar 23 01:46:19 GMT 2021 Temp: 37.2f, Humidity: 98%, Pressure: 28.746in, Wind: 5mph from 124degs, Skies: Overcast skies with drizzle, rain and freezing rain. ___end___ ONSITE STAFF: berkey, mcotter
