It's probably the filter stage again. I'll wait until the dome warms up a little and some data are gathered by the instruments that are running, then I'll pause every instrument and lock the spar and work on the problem. ___end___ SBM COMMENT: Sun Dec 10 17:32:32 GMT 2006 Obs. ___end___ PSPT COMMENT: Sun Dec 10 17:32:39 GMT 2006 Obs. ___end___ SBM COMMENT: Sun Dec 10 17:34:45 GMT 2006 Adjusted the occulting. ___end___ A NEW TAPE HAS BEEN PUT INTO KAIEE DLT DRIVE, Sun Dec 10 17:56:57 GMT 2006 MLSO WEB PAGE IS UP, Sun Dec 10 17:57:00 GMT 2006 Sun Dec 10 18:00:44 GMT 2006 CHIP LSD Sun Dec 10 18:02:27 GMT 2006 CHIP End LSD Sun Dec 10 18:02:42 GMT 2006 CHIP BiasLSD Sun Dec 10 18:03:38 GMT 2006 CHIP End BiasLSD Sun Dec 10 18:03:47 GMT 2006 CHIP Bias Sun Dec 10 18:04:40 GMT 2006 CHIP End Bias Sun Dec 10 18:04:47 GMT 2006 CHIP ReStart Patrol WEATHER COMMENT: Sun Dec 10 18:13:03 GMT 2006 Cirrostratus is getting thicker, pausing mk4. ___end___ Sun Dec 10 18:14:17 GMT 2006 MKIV End Patrol SBM COMMENT: Sun Dec 10 18:19:36 GMT 2006 Paused due to clouds. ___end___ Sun Dec 10 18:50:46 GMT 2006 MKIV Start Cal WEATHER COMMENT: Sun Dec 10 18:53:05 GMT 2006 Clouds thinned, restarted mk4 and sbm. ___end___ Sun Dec 10 19:09:32 GMT 2006 MKIV End Cal Sun Dec 10 19:09:41 GMT 2006 MKIV Start Patrol PICS COMMENT: Sun Dec 10 21:38:57 GMT 2006 I got some good data, now I'm going to try to work on the Halle filter problem without stopping the other instruments, I may bump the spar around until I'm done. ___end___ COMMENT: Mon Dec 11 01:18:54 GMT 2006 Bouncing spar around too much, pausing instruments. ___end___ **PICS PROBLEM**: Mon Dec 11 01:19:23 GMT 2006 Still working on problems. ___end___ Mon Dec 11 01:21:56 GMT 2006 MKIV End Patrol Mon Dec 11 01:24:16 GMT 2006 CHIP End Patrol **PICS PROBLEM**: Mon Dec 11 01:24:27 GMT 2006 I'm going to stop and cleanup for the day, I made good progress with the Halle filter problem. The underlying problem is that the filter weighs a lot and transfers its weight to a small bearing that is held in by friction and a tiny clip on the other end of the leadscrew that drives the filter in and out. I found and fixed a new problem related to the stage, the linear bearing at the O1 end of the stage had worked past the screw-type bearing stop and jammed the action of the stage; so I removed the bearing and cleaned and lubed it then replaced it and used washers to help orient the stops so they work again, the bearings and stops at the lower end were good but I lubed them too. I'm working on a way to hold the leadscrew bearing in better now, I will need to finish that on Tuesday so the PICS is down till then. The tiny setscrew for the leadscrew sprocket was stripped and I couldn't get it out so I drilled and tapped a new hole on the opposite side of the flange, then I installed a beefy capscrew that will be easier to tighten more and yet will be easier to remove too. The leadscrew was out of position and the cable-chain was off, familiar symptoms we've seen and temporarily fixed in the past, I hope to install a much longer lasting fix to that problem on Tuesday. ___end___ NICE MK4 IMAGE: 1906 NICE CHIP IMAGE: 1844 NICE PICSLIMB IMAGE: 1725 Mon Dec 11 02:06:39 GMT 2006 MkIV 00_01.rawmk4 17_32.rawmk4 19_47.rawmk4 21_16.rawmk4 22_47.rawmk4 00_04.rawmk4 17_35.rawmk4 19_50.rawmk4 21_19.rawmk4 22_50.rawmk4 00_07.rawmk4 17_38.rawmk4 19_53.rawmk4 21_21.rawmk4 22_53.rawmk4 00_10.rawmk4 17_41.rawmk4 19_56.rawmk4 21_24.rawmk4 22_56.rawmk4 00_13.rawmk4 17_44.rawmk4 19_59.rawmk4 21_27.rawmk4 22_59.rawmk4 00_16.rawmk4 17_47.rawmk4 20_02.rawmk4 21_30.rawmk4 23_02.rawmk4 00_18.rawmk4 17_50.rawmk4 20_05.rawmk4 21_33.rawmk4 23_05.rawmk4 00_21.rawmk4 17_53.rawmk4 20_08.rawmk4 21_36.rawmk4 23_08.rawmk4 00_24.rawmk4 17_56.rawmk4 20_11.rawmk4 21_39.rawmk4 23_11.rawmk4 00_30.rawmk4 17_59.rawmk4 20_14.rawmk4 21_42.rawmk4 23_14.rawmk4 00_34.rawmk4 18_02.rawmk4 20_17.rawmk4 21_45.rawmk4 23_17.rawmk4 00_37.rawmk4 18_05.rawmk4 20_20.rawmk4 21_48.rawmk4 23_20.rawmk4 00_40.rawmk4 18_08.rawmk4 20_23.rawmk4 21_51.rawmk4 23_23.rawmk4 00_43.rawmk4 18_11.rawmk4 20_26.rawmk4 21_54.rawmk4 23_26.rawmk4 00_46.rawmk4 18_53.rawmk4 20_29.rawmk4 21_57.rawmk4 23_29.rawmk4 00_49.rawmk4 18_59.rawmk4 20_32.rawmk4 22_00.rawmk4 23_31.rawmk4 00_52.rawmk4 19_06.rawmk4 20_34.rawmk4 22_03.rawmk4 23_34.rawmk4 00_55.rawmk4 19_09.rawmk4 20_37.rawmk4 22_08.rawmk4 23_37.rawmk4 00_57.rawmk4 19_12.rawmk4 20_40.rawmk4 22_12.rawmk4 23_40.rawmk4 01_00.rawmk4 19_15.rawmk4 20_43.rawmk4 22_15.rawmk4 23_43.rawmk4 01_03.rawmk4 19_18.rawmk4 20_46.rawmk4 22_18.rawmk4 23_46.rawmk4 01_06.rawmk4 19_21.rawmk4 20_49.rawmk4 22_21.rawmk4 23_49.rawmk4 01_09.rawmk4 19_24.rawmk4 20_52.rawmk4 22_24.rawmk4 23_52.rawmk4 01_12.rawmk4 19_27.rawmk4 20_55.rawmk4 22_27.rawmk4 23_55.rawmk4 01_15.rawmk4 19_30.rawmk4 20_58.rawmk4 22_30.rawmk4 23_58.rawmk4 01_18.rawmk4 19_33.rawmk4 21_01.rawmk4 22_33.rawmk4 c18_50.rawmk4 17_20.rawmk4 19_36.rawmk4 21_04.rawmk4 22_36.rawmk4 c18_56.rawmk4 17_23.rawmk4 19_39.rawmk4 21_07.rawmk4 22_39.rawmk4 c19_03.rawmk4 17_26.rawmk4 19_42.rawmk4 21_10.rawmk4 22_42.rawmk4 17_29.rawmk4 19_44.rawmk4 21_13.rawmk4 22_45.rawmk4
