We opened a previous file from November 24, 2022 and checked those values, which were x=62.01 y=4.21. We copied the old values into the current document, saved and exited. Currently restarting to see if that worked. ___end___ Sat Mar 22 19:01:25 GMT 2025 KCOR End Patrol Sat Mar 22 19:01:35 GMT 2025 KCOR End Patrol Sat Mar 22 19:06:13 GMT 2025 KCOR Start Synoptic Patrol GENERAL COMMENT BY Observer: Sat Mar 22 19:13:37 GMT 2025 We lost internet, can't update UCoMP till we figure this out. ___end___ GENERAL COMMENT BY Observer: Sat Mar 22 19:17:59 GMT 2025 Power cycling the internet to see if it brings it back ___end___ Sat Mar 22 19:34:21 GMT 2025 KCOR End Patrol Sat Mar 22 19:34:28 GMT 2025 KCOR End Patrol Sat Mar 22 19:35:47 GMT 2025 KCOR Start Synoptic Patrol Sat Mar 22 19:36:14 GMT 2025 KCOR End Patrol GENERAL COMMENT BY Observer: Sat Mar 22 19:37:38 GMT 2025 Spar hit the ladder ___end___ Sat Mar 22 19:40:28 GMT 2025 KCOR Start Synoptic Patrol Sat Mar 22 19:50:08 GMT 2025 KCOR End Patrol GENERAL COMMENT BY Observer: Sat Mar 22 19:53:33 GMT 2025 Replacing cover on Ucomp ___end___ Sat Mar 22 19:56:32 GMT 2025 KCOR Start Synoptic Patrol Sat Mar 22 20:04:50 GMT 2025 KCOR End Patrol Sat Mar 22 20:04:51 GMT 2025 KCOR Start Calibration script: c:\kcor\mlso-calibration22deg-20171025.ini GENERAL COMMENT BY Observer: Sat Mar 22 20:06:16 GMT 2025 Batteries at 97% ___end___ Sat Mar 22 20:20:04 GMT 2025 KCOR End Calibration Script Sat Mar 22 20:20:21 GMT 2025 KCOR Start Synoptic Patrol Sat Mar 22 20:20:21 GMT 2025 KCOR Start Synoptic Patrol Sat Mar 22 21:08:21 GMT 2025 Running UCOMP Cookbook synoptic-original-lines.cbk line 0 Sat Mar 22 21:46:25 GMT 2025 Running UCOMP Cookbook synoptic-original-lines.cbk line 0 GENERAL COMMENT BY Observer: Sat Mar 22 21:49:39 GMT 2025 Lost internet again ___end___ UCoMP COMMENT BY Observer: Sat Mar 22 21:52:08 GMT 2025 Turns out it was an ordering issue with the instrument_config.ini. We have put it bbaack into the correct order and now everything is working just fine on UCoMP now. Taking data but we have most likely less than an hour as clouds are starting to roll in from the West. ___end___ GENERAL COMMENT BY Observer: Sat Mar 22 22:01:20 GMT 2025 Lost internet connection ___end___ GENERAL COMMENT BY Observer: Sat Mar 22 22:12:56 GMT 2025 Having intermittent internet issues; Tom sending out an email to see what may be going on. ___end___ UCoMP COMMENT BY mlso: Sat Mar 22 22:12:11 GMT 2025 UCoMP occulter issues came in due to a slightly reorganization of the config files to be more human readable and debug-able if issues with the occulter came up. Unfortunately I forgot that that the source code had a hard coded order expected for stage config data. During the config cleanup I forgot this fact and assumed that the code looked up stage information by stage name. This lead to the difficult to debug condition in that the occulter stage worked as expected when commanded to an absolute position; but looked up the wrong in-beam positions. So all of the observing code steps that made commands to move IN failed. The stage order in the config file has been restored; and I am working on some plans to change the way we load the config; to work by name instead of assumed order to avoid this type of bug in the future. This implementation will need to wait until normal power is restored. ___end___ Sat Mar 22 22:23:10 GMT 2025 Running UCOMP Cookbook waves_1074_1hour.cbk line 0 Sat Mar 22 22:32:22 GMT 2025 KCOR End Patrol WEATHER COMMENT: Observer: Sat Mar 22 22:41:11 GMT 2025 Clouds are coming in and pilot is heading up. ___end___ GENERAL COMMENT BY Observer: Sat Mar 22 22:48:07 GMT 2025 Battery at 99% ___end___ GENERAL COMMENT BY lisapg: Sat Mar 23 02:07:01 GMT 2025 705am landed and made it to MLSO building. 708am batteries at 64% and load between 230-300w. Generator started; UComp up to temp, Kcor at 31C but climbing. Typical behavior this time of year 712am Verified batteries were charging and started to power the building. 718am the Yeti that was powering the firewall and cosmic had completely drained, move them to wall power and started to recharge the yeti 727am troubleshooting getting the logger online 731am logger up and running, Marc got the dome open and the instruments on Sun; Kcor not quite above the dome Everything after this was written down in the logger, so I don't know the time stamps. - brought up UComp, cameras would not initialize, shut down labview GUI and power cycled the cameras. Came back fine. Started to run into an issue when centering the occulter on UComp; occulter led wasn't lit, position tracker said it was at 0 and shuttler was in beam. Had Marc check where the occulter was physically and saw it was out of beam. We went through the motions of using the move absolute while we had the cover open to make sure the mechanism was working. Was working as intended, power cycled the computer to see if that would fix it, it did not. During this time we got Kcor up and running; SGS oscillated a bit when trying to use the automatic zero offset but stopped when Kcor O1 was in focus. Power cycling Ucomp computer did not fix the problem, so we pulled up our issues git hub page and went to find a situation similar. Was able to find the correct steps and followed through with them. At some point, the hardware had set the mech in beam occulter to x=0, y=1. Looked at a previous good set of numbers and followed the document steps to copy them over. Saved them and restarted labview. However, this did not fix the problem. Power cycled the ucomp computer just in case it needed it. Roughly 915am, we lost internet and this happened at least two, maybe three times through out the day. Ben pinged us around that time and starting trouble shooting with him. After an extensive amount of block diagrams and different GUIs we resolved the problem at 1130am by moving where the read out for the occulter x,y were to where they were in the old document. Ben has a much better explanation in the log for all that happened. Started taking data immediately and sent out emails to let everyone know. At that time, we started to see clouds pop up on the West, so I started checking in with the pilot as often as I felt was needed to insure we didn't over extend our stay and missed the heli while Marc monitored the instruments. At one point we lost internet and Ucomp seemed to have lost contact with Kodiak and opened its recipe loader. Ben advised us to cancel and as the internet had come back up, Ucomp was happy again. Around 1230pm we got the call to button up as the pilot was coming. We shut down Kcor first and tried to let Ucomp run as long as we could as we just got to 1074waves. Clouds can in roughly 1244pm and we shut everything down. Generator was turned off at 1248pm and unfortunately I shut down Kodiak before reading what the draw was on the batteries. Rough day but I'm extremely happy we got data. ___end___ ONSITE STAFF: lisapg, mcotter
