Troubleshooting this morning appeared to show an interaction between the megaraid and NI daq board. From what I can tell it seems like there was too much power draw and the booting failed. The main symptom was on boot up the screen would flash a few times over 10-15 seconds before it looked like the system shed power (fans began to slow) before the motherboard apparently rebooted. With either the Raid board or the DAQ board the system was able to fully boot. I am not sure why we were able to startup and run yesterday after installing the megaraid board. I think the rest of the system (motherboard and power supply) was just barely able to work with the new raid board so we just got lucky/unlucky with the startup yesterday. To recover from this the old Areca board has been installed in the system and the raid set is currently rebuilding. For now, we are taking data on the system disk. We will begin using the raid array once it is ready. ___end___ Tue Oct 19 17:21:38 GMT 2021 Kcor Focus/alignment program exited Tue Oct 19 17:23:08 GMT 2021 KCOR Start Synoptic Patrol Tue Oct 19 17:27:19 GMT 2021 Running UCOMP Cookbook dark_80ms_2beam_16sums_BOTH.cbk line 0 UCoMP COMMENT BY berkey: Tue Oct 19 17:27:53 GMT 2021 Change the UCoMP focus algorithm to use 1074 instead of 1083, I think this should make alignment a little easier by getting rid of the bright prominence material. ___end___ Tue Oct 19 17:28:36 GMT 2021 Running UCOMP Cookbook 637_Scan.cbk line 0 Tue Oct 19 17:31:01 GMT 2021 Running UCOMP Cookbook 656_Scan.cbk line 0 Tue Oct 19 17:33:02 GMT 2021 Running UCOMP Cookbook 789_Scan.cbk line 0 Tue Oct 19 17:35:04 GMT 2021 Running UCOMP Cookbook 1074_Scan.cbk line 0 Tue Oct 19 17:37:07 GMT 2021 Running UCOMP Cookbook 1079_Scan.cbk line 0 Tue Oct 19 17:39:08 GMT 2021 Running UCOMP Cookbook 1083_Scan.cbk line 0 Tue Oct 19 17:41:08 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal_flat.cbk line 0 GENERAL COMMENT BY lisapg: Tue Oct 19 17:45:36 GMT 2021 The new Guider Zero-Point Offset values that I found to work this morning with the new guider was X(RA) 55 Y(Dec) -10 ___end___ Tue Oct 19 18:06:16 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 0 Tue Oct 19 18:09:46 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 1 Tue Oct 19 18:23:20 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 10 Tue Oct 19 18:58:10 GMT 2021 KCOR End Patrol Tue Oct 19 18:58:22 GMT 2021 KCOR End Patrol GENERAL COMMENT BY lisapg: Tue Oct 19 18:58:10 GMT 2021 Sky is getting too bright for Kcor but still fine for UCoMP; Kcor idled for now. ___end___ Tue Oct 19 19:02:19 GMT 2021 KCOR Start Synoptic Patrol Tue Oct 19 19:18:33 GMT 2021 Running UCOMP Cookbook dark_80ms_2beam_16sums_BOTH.cbk line 0 Tue Oct 19 19:26:56 GMT 2021 Running UCOMP Cookbook dark_80ms_2beam_16sums_BOTH.cbk line 1 Tue Oct 19 19:26:57 GMT 2021 UCoMP Paused for clouds Tue Oct 19 19:52:23 GMT 2021 Kcor Focus/alignment program exited Tue Oct 19 19:53:51 GMT 2021 KCOR Start Synoptic Patrol Tue Oct 19 19:54:19 GMT 2021 UCoMP Restarted from pause Tue Oct 19 19:55:23 GMT 2021 Running UCOMP Cookbook 637_Pol_Calibrate.cbk line 0 Tue Oct 19 20:00:03 GMT 2021 Running UCOMP Cookbook 656_Pol_Calibrate.cbk line 0 Tue Oct 19 20:04:19 GMT 2021 Running UCOMP Cookbook 789_Pol_Calibrate.cbk line 0 Tue Oct 19 20:08:37 GMT 2021 Running UCOMP Cookbook 1074_Pol_Calibrate.cbk line 0 Tue Oct 19 20:12:56 GMT 2021 Running UCOMP Cookbook 1079_Pol_Calibrate.cbk line 0 Tue Oct 19 20:17:12 GMT 2021 Running UCOMP Cookbook 1083_Pol_Calibrate.cbk line 0 Tue Oct 19 20:19:15 GMT 2021 KCOR End Patrol Tue Oct 19 20:19:16 GMT 2021 KCOR Start Calibration script: c:\kcor\mlso-calibration22deg-20171025.ini Tue Oct 19 20:21:30 GMT 2021 Running UCOMP Cookbook waves_1074_1hour.cbk line 0 Tue Oct 19 20:34:32 GMT 2021 KCOR End Calibration Script Tue Oct 19 20:34:49 GMT 2021 KCOR Start Synoptic Patrol Tue Oct 19 20:34:50 GMT 2021 KCOR Start Synoptic Patrol GONG COMMENT BY lisapg: Tue Oct 19 20:57:14 GMT 2021 Went down to the GONG shelter and adjusted the H-alpha target as per Detricks request.

Found new values: RA_KC=18 (was 40.5 and 70 before April) RA_Ti=.006 (was .008) Dec_KC= 250 (was 300) DEC_Ti=.0059 (was .0058) Initial tuning showed we could get into a violent noisy 1.4 Hz RA oscillation when we de-tuned to find its oscillation frequency. With an intervention in the RA the new 2.7Hz oscillation amplitudes where considerable smaller and no longer made enough noise to be heard from the dome floor. Due to the loud 1.4Hz oscillation, we ran a test to checked for bulk motion of the RA assembly when changing directions rapidly from +5 to -5V, but we saw no bulk motion. However when moving east we did hear a high pitch noise coming from the worm gear. After a bit of inspection including loosen the stops that prevents the RA assembly with motor from moving in RA around the drive rollers. It was found that the noise seemed to be related to tooth engagement at the very end of the worm gear (farthest from the motor). It seemed like the worm gear was mostly enguaging with the planetary gear at the worm tip and part of the worm cover may have been dragging against the planatry gear. With the worm gear tipped up slightly we appeared to get good meshing toward the middle of the gear but no more noise/dragging. With ~3mm of shims placed between the RA motor and the dog house we found we could maintain this good position, while maintaining gear meshing. It looks like we had a small degradation in sky conditions while during this work with more aerosols in the sky. But Based on a a couple spot checks before and after the work the RA Mean standard deviation has gone from ~.003 to .002 so I think we should see an improvement in spar pointing. ___end___ Wed Oct 20 00:41:28 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 0 Wed Oct 20 01:36:27 GMT 2021 UCoMP Paused for clouds Wed Oct 20 01:44:05 GMT 2021 UCoMP Restarted from pause Wed Oct 20 01:48:59 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal.cbk line 28 GENERAL COMMENT BY berkey: Wed Oct 20 01:52:05 GMT 2021 The new guider location seems to preform well mid-day. But as we get near the horizon (morning and evening) the new guider location seems to have a quicker departure from ucomp/kcor than what we saw with the old guider postion. probally worth a few more days or testing but right now the old guider position looks better. ___end___ Wed Oct 20 02:15:52 GMT 2021 Running UCOMP Cookbook dark_80ms_2beam_16sums_BOTH.cbk line 0 Wed Oct 20 02:17:09 GMT 2021 Running UCOMP Cookbook 1074_Pol_Calibrate.cbk line 0 Wed Oct 20 02:21:52 GMT 2021 Running UCOMP Cookbook all_wavelenght_coronal_flat.cbk line 0 GENERAL COMMENT BY berkey: Wed Oct 20 02:22:19 GMT 2021 Kcor/Ucomp to guider offset seems to have settled down. And we are seeing a slower variation with time. Seems like we must have pass from one regime to the other around 2:00UTC. ___end___ Wed Oct 20 02:29:32 GMT 2021 KCOR End Patrol ONSITE STAFF: berkey, lisapg
