I fixed reset the position to the proper value. I fixed the checkout scripts for the file extension problem due to other users preferences settings. Post primary relaxed spicam out-of-focus images (before collimation) The threat of rain closed us at this point. Russet compared SPIcam out-of-focus images taken last night with SPIcam with tonights, It didn't appear to change collimation much. We homed the secondary Started raining about 15 mins after we closed. We re-opened around 03:00 and used the Shack Hartmann to check collimation after the secondary home. After the Shack Hartmann we slewed the telescope to change to the NA2 port and we got repeated Alt motion errors. Investigation showed we ran over a moth. Alt drive cleaned several times over several up/down passes to remove the gunk. 20 point pointing model (due to limited time) Implemented model. Russet checked pointing at NA1 as well. I took TSPEC images during the 2nd half of the night as well. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 23:35 ecamera 222( -569) 36 59 13.9 14.7 15.4 14.6 14.1 ND4 1.10 03:33 shack 525( 1217) -13 63 12.3 12.5 13.8 12.4 12.1 -- 1.20 04:26 guider 627( 933) 62 36 12.2 12.1 13.0 12.0 11.9 R 1.44 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp C Dewp C MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 62 45 11 80 (E) 222 cloudy lt rain 17:00 59 47 10 72 (ENE) 574 cloudy none 18:00 58 49 20 56 (NE) 284 cloudy none 19:00 57 45 14 62 (ENE) 201 cloudy none 20:00 59 42 7 356 (N) 244 cloudy rain 21:00 57 43 11 30 (NNE) 248 cloudy none 22:00 56 43 11 80 (E) 211 ptly cldy none 23:00 58 41 12 58 (ENE) 209 mstly clr none 00:00 58 41 18 59 (ENE) 185 ptly cldy lt rain 01:00 50 48 27 69 (ENE) 284 ptly cldy humid 02:00 50 49 18 70 (ENE) 274 mstly cldy humid 03:00 52 47 17 70 (ENE) 249 mstly clr none 04:00 54 42 11 55 (NE) 119 ptly cldy none 05:00 54 40 15 51 (NE) 102 ptly cldy none Note: the wind was coming from the azimuth listed.
