----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Sun Dec 11 17:22:03 GMT 2005 Year: 05 Doy: 345 Observer: koon WEATHER COMMENT: Sun Dec 11 17:22:07 GMT 2005 Clear sky, wind =5 mph from the SE, temp=38F. ___end___ **MLSO PROBLEM**: Sun Dec 11 17:27:42 GMT 2005 Spar guider isn't locking onto sun, first noticed while up in dome pointing telescope, also noticed a filter over the Guider Telescope. Repeated resets aren't helping. Will read logs and email to see what is in progress before trying anything else to get guider working and starting observations. ___end___ **MLSO PROBLEM**: Sun Dec 11 17:34:38 GMT 2005 It looks like guiding is stable now, will start obs, it did take several repointing/reset cycles though. ___end___ Sun Dec 11 17:36:08 GMT 2005 MKIV Start Patrol Sun Dec 11 17:38:46 GMT 2005 CHIP Start Patrol Sun Dec 11 17:39:07 GMT 2005 PICS Start Patrol PSPT COMMENT: Sun Dec 11 18:04:03 GMT 2005 Observing. ___end___ **PICS PROBLEM**: Sun Dec 11 18:04:35 GMT 2005 Stalled with Optics:Busy and Sync:40,42. Did a Kill/Run cycle to fix. ___end___ **CHIP PROBLEM**: Sun Dec 11 18:08:00 GMT 2005 Stalled also with Optics:Busy, did a Kill/Run cycle to fix. ___end___ PSPT COMMENT: Sun Dec 11 18:22:31 GMT 2005 Wasn't exited from IDL this morning like usual, exited before starting Pspt. ___end___ Sun Dec 11 18:29:30 GMT 2005 MKIV End Patrol Sun Dec 11 18:29:43 GMT 2005 MKIV Start Cal Sun Dec 11 18:36:00 GMT 2005 PICS Start Patrol Sun Dec 11 18:40:05 GMT 2005 CHIP Start Patrol **PICS PROBLEM**: Sun Dec 11 18:35:43 GMT 2005 The Kill/Run cycle didn't fix the problem, it kept giving the message about the Mechanism Control Computer not being ready. I first rebooted Nene but that didn't fix it, cycling power to the MCC did fix the problem. This morning when I logged in I noticed that someone had logged into Nene, Kii, and Nahenahe about 4:05 am on 12/10 GMT, that would be about 6:05 pm last night NSToops that is HST (Hawaiian Standard Time), not NST. Observations appear to be back to normal. ___end___ **CHIP PROBLEM**: Sun Dec 11 18:41:34 GMT 2005 Same recovery as noted for PICS, see comment above. ___end___ Sun Dec 11 18:49:05 GMT 2005 MKIV End Cal Sun Dec 11 19:08:49 GMT 2005 PICS End Patrol **PICS PROBLEM**: Sun Dec 11 19:08:49 GMT 2005 Halle filter isn't being moved out for limb images, pausing obs to check it. ___end___ Sun Dec 11 19:25:45 GMT 2005 CHIP End Patrol **PICS PROBLEM**: Sun Dec 11 19:24:00 GMT 2005 Found cable-chain off of gears, and possibly a bad actuator for the In limit switch, switches seems normal. I need to stop obs and position the spar differently to be able to work on the problem. Pausing spar instruments for a while. ___end___ Sun Dec 11 19:31:21 GMT 2005 MKIV End Patrol Sun Dec 11 21:24:17 GMT 2005 MKIV Start Patrol Sun Dec 11 21:24:53 GMT 2005 CHIP Start Patrol Sun Dec 11 21:25:19 GMT 2005 PICS Start Patrol **PICS PROBLEM**: Sun Dec 11 21:25:30 GMT 2005 I see 2 possible causes of the problem. The first possibility is the one I concentrated one and made some changes to, it looked like the IN limit switch for the Halle filter was activating too close to the end of possible stage travel, thus if it overdrove just maybe 10-20 degrees revolution of the stage drive leadscrew then the stage limit was met and the possible torque from the drive motor was getting transformed into an outward stress on the leadscrew bearing at the cable-chain side, eventually that drove the bearing out and then the leadscrew followed enough to loosen the cable-chain tension to the point where the cable-chain junped off the gears, that would leave the Halle undrivable. So working on that assumption I removed the IN limit switch actuator tab and reversed the orientation to allow better switch actuation and better adjustability. I remounted that tab without the adjustment screw since it is unnecessary and won't work with that orientation. That gave about 180 degrees of rotation to the leadscrew after IN switch activation before stage end limit. Reassembled it all and it works fine. The other possibility is that the leadscrew slowly works its bearing out of place from normal wear and tear. I'll monitor that possibility over time. ___end___ MKIV COMMENT: Sun Dec 11 21:45:26 GMT 2005 It looks like the scan images are noticeably better than they have been recently, probably due to the better guiding due to the filter over the guider telescope. ___end___ A NEW PSPT EXABYTE IS LOADED ON KENOBI Sun Dec 11 21:54:53 GMT 2005 **PSPT PROBLEM**: Sun Dec 11 21:54:56 GMT 2005 Crashed at 1948 with "Set wavelength CAK narrow" message, restarted. Didn't get it right away due to being busy with other problems. ___end___ A NEW TAPE HAS BEEN PUT INTO KAIEE DLT DRIVE, Sun Dec 11 21:58:10 GMT 2005 Mon Dec 12 02:22:41 GMT 2005 CHIP End Patrol Mon Dec 12 02:23:17 GMT 2005 PICS End Patrol Mon Dec 12 02:24:18 GMT 2005 MKIV End Patrol NICE MK4 IMAGE: 1802 NICE PICSDISC IMAGE: 1851 NICE PICSLIMB IMAGE: 2144 NICE CHIP IMAGE: 1919 Mon Dec 12 02:36:43 GMT 2005 MkIV 00_00.rawmk4 01_22.rawmk4 17_56.rawmk4 21_27.rawmk4 22_49.rawmk4 00_03.rawmk4 01_25.rawmk4 17_59.rawmk4 21_30.rawmk4 22_52.rawmk4 00_05.rawmk4 01_28.rawmk4 18_02.rawmk4 21_33.rawmk4 22_55.rawmk4 00_08.rawmk4 01_31.rawmk4 18_05.rawmk4 21_36.rawmk4 22_58.rawmk4 00_11.rawmk4 01_34.rawmk4 18_08.rawmk4 21_38.rawmk4 23_01.rawmk4 00_14.rawmk4 01_37.rawmk4 18_11.rawmk4 21_41.rawmk4 23_04.rawmk4 00_17.rawmk4 01_39.rawmk4 18_14.rawmk4 21_44.rawmk4 23_07.rawmk4 00_20.rawmk4 01_42.rawmk4 18_17.rawmk4 21_47.rawmk4 23_10.rawmk4 00_23.rawmk4 01_45.rawmk4 18_20.rawmk4 21_50.rawmk4 23_13.rawmk4 00_26.rawmk4 01_48.rawmk4 18_23.rawmk4 21_53.rawmk4 23_15.rawmk4 00_29.rawmk4 01_51.rawmk4 18_26.rawmk4 21_56.rawmk4 23_18.rawmk4 00_32.rawmk4 01_54.rawmk4 18_32.rawmk4 21_59.rawmk4 23_21.rawmk4 00_35.rawmk4 01_57.rawmk4 18_38.rawmk4 22_02.rawmk4 23_24.rawmk4 00_38.rawmk4 02_00.rawmk4 18_49.rawmk4 22_05.rawmk4 23_27.rawmk4 00_41.rawmk4 02_03.rawmk4 18_52.rawmk4 22_08.rawmk4 23_30.rawmk4 00_44.rawmk4 02_06.rawmk4 18_55.rawmk4 22_11.rawmk4 23_33.rawmk4 00_47.rawmk4 02_09.rawmk4 18_58.rawmk4 22_14.rawmk4 23_36.rawmk4 00_50.rawmk4 02_12.rawmk4 19_01.rawmk4 22_17.rawmk4 23_39.rawmk4 00_53.rawmk4 02_15.rawmk4 19_04.rawmk4 22_20.rawmk4 23_42.rawmk4 00_55.rawmk4 02_18.rawmk4 19_07.rawmk4 22_23.rawmk4 23_45.rawmk4 00_58.rawmk4 02_21.rawmk4 19_10.rawmk4 22_26.rawmk4 23_48.rawmk4 01_01.rawmk4 17_36.rawmk4 19_13.rawmk4 22_28.rawmk4 23_51.rawmk4 01_04.rawmk4 17_39.rawmk4 19_16.rawmk4 22_31.rawmk4 23_54.rawmk4 01_07.rawmk4 17_42.rawmk4 19_19.rawmk4 22_34.rawmk4 23_57.rawmk4 01_10.rawmk4 17_45.rawmk4 19_22.rawmk4 22_37.rawmk4 c18_29.rawmk4 01_13.rawmk4 17_47.rawmk4 19_25.rawmk4 22_40.rawmk4 c18_35.rawmk4 01_16.rawmk4 17_50.rawmk4 19_28.rawmk4 22_43.rawmk4 c18_42.rawmk4 01_19.rawmk4 17_53.rawmk4 21_24.rawmk4 22_46.rawmk4Fetched URL: https://download.hao.ucar.edu/d5/mlso/log/observer/2005/mlso.2005d345.olog
