Put away some plumbing things like extra hose (next to tool drawers in PSPT dome), and hose connectors (in box above PSPT cooler with PSPT hose spares and connectors). Put rest of screws in spar plates, and threw away more rubbish from deployment time. Will send last 2 white boxes to Andy later today, from FedEx. ___end___ WEATHER COMMENT: Wed Mar 24 21:41:53 GMT 2010 Sky brightness stayed high pretty much all day. Most of the images look kind of clunky. ___end___ WEATHER COMMENT: Wed Mar 24 22:00:59 GMT 2010 Low clouds passing by. ___end___ **PSPT PROBLEM COMMENT BY DARRYL**: Wed Mar 24 22:41:54 GMT 2010 The telescope was oscillating around noon even without much wind, I put pieces of hose as dampers between the sun shield and the camera housing up front to keep that shield from adding to the oscillations in RA as it shook. As we watched the telescope we saw the oscillations go away when the clouds passed over, that seems to imply that reducing the gain in the guider could eliminate the oscillations, because we already know from past experimentation that the oscillation only happens when the guider is turned on. Ben suggested changing the gain in the software and found a way to do it temporarily with commands from the PC, he's now trying to find a way to permanently change the RA gain to be half of what it was - that seems to allow my induced (hand-pushed) oscillations to damp out and still allow guiding. This isn't the best day to do the testing because of the clouds but this looks like a great way to fix our old oscillations problem. ___end___ Wed Mar 24 22:58:19 GMT 2010 MKIV End Patrol Wed Mar 24 22:59:40 GMT 2010 CHIP End Patrol Wed Mar 24 23:35:36 GMT 2010 MkIV 17_11.rawmk4 19_07.rawmk4 20_39.rawmk4 21_32.rawmk4 22_25.rawmk4 17_14.rawmk4 19_10.rawmk4 20_42.rawmk4 21_35.rawmk4 22_28.rawmk4 18_05.rawmk4 19_17.rawmk4 20_45.rawmk4 21_38.rawmk4 22_31.rawmk4 18_07.rawmk4 19_23.rawmk4 20_48.rawmk4 21_41.rawmk4 22_34.rawmk4 18_13.rawmk4 19_29.rawmk4 20_51.rawmk4 21_44.rawmk4 22_37.rawmk4 18_20.rawmk4 20_01.rawmk4 20_54.rawmk4 21_47.rawmk4 22_40.rawmk4 18_24.rawmk4 20_04.rawmk4 20_57.rawmk4 21_50.rawmk4 22_43.rawmk4 18_27.rawmk4 20_07.rawmk4 21_00.rawmk4 21_53.rawmk4 22_46.rawmk4 18_30.rawmk4 20_10.rawmk4 21_03.rawmk4 21_56.rawmk4 22_49.rawmk4 18_33.rawmk4 20_13.rawmk4 21_06.rawmk4 21_59.rawmk4 22_52.rawmk4 18_36.rawmk4 20_16.rawmk4 21_09.rawmk4 22_02.rawmk4 22_55.rawmk4 18_38.rawmk4 20_19.rawmk4 21_12.rawmk4 22_05.rawmk4 c19_13.rawmk4 18_41.rawmk4 20_22.rawmk4 21_15.rawmk4 22_08.rawmk4 c19_20.rawmk4 18_44.rawmk4 20_25.rawmk4 21_18.rawmk4 22_11.rawmk4 c19_26.rawmk4 18_47.rawmk4 20_28.rawmk4 21_21.rawmk4 22_14.rawmk4 18_50.rawmk4 20_31.rawmk4 21_24.rawmk4 22_16.rawmk4 19_01.rawmk4 20_33.rawmk4 21_26.rawmk4 22_19.rawmk4 19_04.rawmk4 20_36.rawmk4 21_29.rawmk4 22_22.rawmk4
