Looks like the cameras were not coming up properly. Cameras were powered cycled by pulling the orange power cord in the back of the ucomp rack counting to 20 then plugging the cord back in. UCoMP controller code was forced to stop with the STOP sign and then restarted at that point everything ran smoothly. Should be able to automate this step once with computer control of the epdu. ___end___ Mon Nov 29 18:06:28 GMT 2021 UCoMP Restarted from pause Mon Nov 29 18:08:16 GMT 2021 UCoMP Paused for clouds Mon Nov 29 18:08:50 GMT 2021 UCoMP Restarted from pause Mon Nov 29 18:18:47 GMT 2021 UCoMP Paused for clouds GENERAL COMMENT BY mcotter: Mon Nov 29 18:20:59 GMT 2021 Dome closed for fast fog. ___end___ GENERAL COMMENT BY mcotter: Mon Nov 29 18:25:30 GMT 2021 PM Blew off Kcor O1 ___end___ Mon Nov 29 18:51:25 GMT 2021 UCoMP Restarted from pause Mon Nov 29 18:56:02 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 0 Mon Nov 29 18:58:36 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 4 Mon Nov 29 19:22:27 GMT 2021 UCoMP Paused for clouds GENERAL COMMENT BY mcotter: Mon Nov 29 19:29:39 GMT 2021 Closed again for clouds. ___end___ UCoMP COMMENT BY mcotter: Mon Nov 29 19:33:36 GMT 2021 Noticed the ucomp camera water pump was making a strange noise. Seemed the impeller was either cavitating or there some else was wrong with it. No air pockets were seen near the motor; after moving the spar to vertical the noise stopped; however it briefly started again when the input and output hoses were poked. Camera temps look nominal so it seems like the pump must be working or else it had just failed. ___end___ GENERAL COMMENT BY mcotter: Mon Nov 29 20:10:28 GMT 2021 Building camera seems to have went offline during the power outage yesterday. ___end___ GENERAL COMMENT BY mcotter: Mon Nov 29 20:26:47 GMT 2021 Running on the backup raspbery pi computer. ___end___ KCOR COMMENT BY mcotter: Mon Nov 29 22:49:39 GMT 2021 Inspected kcor aft end of light leaks. Found a few 1/4-20 holes and similar sized openings around the box that were covered with tap. We also found there was a leak around all of the D-sub and fiber connections on the south side. Black cloth baffles were installed over the south panel to cover the connector light leaks. And another set of cloth baffles were installed over the cameras, pbs and modulator. This should reduce stray light in the box. ___end___ GENERAL COMMENT BY mcotter: Mon Nov 29 22:52:28 GMT 2021 Bit of hail about 20 minutes ago whole site was turned with, but it has now mostly melted off. ___end___ Mon Nov 29 23:06:32 GMT 2021 UCoMP Restarted from pause Tue Nov 30 00:12:01 GMT 2021 Kcor Focus/alignment program exited Tue Nov 30 00:12:29 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 0 GENERAL COMMENT BY mcotter: Tue Nov 30 00:13:24 GMT 2021 Looks like we have a 30 minute window of clear skies between the clouds/rain. ___end___ Tue Nov 30 00:23:30 GMT 2021 UCoMP Paused for clouds GENERAL COMMENT BY mcotter: Tue Nov 30 00:26:46 GMT 2021 Guess it was only a 15 minute window. ___end___ GENERAL COMMENT BY mcotter: Tue Nov 30 00:37:31 GMT 2021 Rain and fog. ___end___ GENERAL COMMENT BY mcotter: Tue Nov 30 02:04:33 GMT 2021 Crazy weather today. ___end___ Tue Nov 30 02:05:44 GMT 2021 UCoMP Restarted from pause ONSITE STAFF: berkey, mcotter
