I climbed up and checked out sensors, there are signs of a short circuit at the edge detecting sensor where old white wires touch a connector for the O1 wheel for mk4. I'm pausing instruments to check it out better. ___end___ WEATHER COMMENT: Mon Sep 13 01:20:40 GMT 2004 Partly cloudy with low clouds. ___end___ **MLSO PROBLEM**: Mon Sep 13 01:20:59 GMT 2004 I replaced the old wiring that shorted due to UV aging, for both the edge sensor and the cloud sensor, now the edge sensor triggers a relay in that gray box on the top of the circular dome wall - like it should but wasn't doing earlier. The Cloud sensor triggers a relay too like it did earlier. But despite relays clicking I can't get the dome to rotate in automatic mode, though it does rotate in manual mode. Maybe a relay contact got damaged when the short circuit happened and now that needs smoothing or replacing. I'll see what I can find before I leave. ___end___ Mon Sep 13 01:58:30 GMT 2004 CHIP Start Patrol **MLSO PROBLEM**: Mon Sep 13 01:41:12 GMT 2004 One of the contacts on the dome edge sensor relay is damaged and the circuit board looks like some components are lightly toasted. I can't find any spare relay of that type. I'll try to get some data. The dome edge relay is removed from the gray box now but we can still manually rotate the dome until we get a new relay. I'll ask Allen to take a look at it since I'm running out of time today, maybe he can fix it or spec it for Ron and get a couple ordered for us. ___end___ Mon Sep 13 01:58:45 GMT 2004 PICS Start Patrol Mon Sep 13 02:02:32 GMT 2004 MKIV Start Patrol MKIV COMMENT: Mon Sep 13 02:03:10 GMT 2004 Centered occulting. ___end___ NICE PICSDISC IMAGE: 1746 NICE PICSLIMB IMAGE: 1747 NICE MK4 IMAGE: 1745 NICE CHIP IMAGE: 1740 Mon Sep 13 02:11:12 GMT 2004 CHIP End Patrol Mon Sep 13 02:11:27 GMT 2004 PICS End Patrol Mon Sep 13 02:14:43 GMT 2004 MKIV End Patrol Mon Sep 13 02:38:39 GMT 2004 MkIV 02_02.rawmk4 17_39.rawmk4 18_42.rawmk4 19_35.rawmk4 20_28.rawmk4 02_05.rawmk4 17_42.rawmk4 18_45.rawmk4 19_38.rawmk4 20_31.rawmk4 02_08.rawmk4 17_45.rawmk4 18_48.rawmk4 19_41.rawmk4 20_34.rawmk4 02_11.rawmk4 17_47.rawmk4 18_51.rawmk4 19_44.rawmk4 20_40.rawmk4 16_57.rawmk4 17_50.rawmk4 18_54.rawmk4 19_47.rawmk4 20_43.rawmk4 17_01.rawmk4 17_53.rawmk4 18_57.rawmk4 19_50.rawmk4 20_46.rawmk4 17_03.rawmk4 17_56.rawmk4 19_00.rawmk4 19_53.rawmk4 20_49.rawmk4 17_06.rawmk4 17_59.rawmk4 19_03.rawmk4 19_55.rawmk4 20_52.rawmk4 17_09.rawmk4 18_02.rawmk4 19_05.rawmk4 19_58.rawmk4 20_55.rawmk4 17_12.rawmk4 18_05.rawmk4 19_08.rawmk4 20_01.rawmk4 20_58.rawmk4 17_15.rawmk4 18_12.rawmk4 19_11.rawmk4 20_04.rawmk4 21_01.rawmk4 17_18.rawmk4 18_18.rawmk4 19_14.rawmk4 20_07.rawmk4 21_04.rawmk4 17_21.rawmk4 18_24.rawmk4 19_17.rawmk4 20_10.rawmk4 21_07.rawmk4 17_24.rawmk4 18_27.rawmk4 19_20.rawmk4 20_13.rawmk4 21_10.rawmk4 17_27.rawmk4 18_30.rawmk4 19_23.rawmk4 20_16.rawmk4 c18_09.rawmk4 17_30.rawmk4 18_33.rawmk4 19_26.rawmk4 20_19.rawmk4 c18_15.rawmk4 17_33.rawmk4 18_36.rawmk4 19_29.rawmk4 20_22.rawmk4 c18_21.rawmk4 17_36.rawmk4 18_39.rawmk4 19_32.rawmk4 20_25.rawmk4
