UL and LR quads both dropped, but LR quad came back a few minutes later. Motion error in alt at 61 slewing downwards in the east, very short slew. Agile pointing was off by about an arcminute at the start of OU04's observations. Rotation (also checked at checkout) was not the culprit. Then we saw a drift with AGILE at 02:29, Russet logged in and we homed the secondary. (Separate email with more details.) Very thin clouds at the end of the night, but mostly good weather! ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- OU04 AGILE T/H 02:31 03:02 Pointing jump + mirror homing ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:17 arctic 312( 1335) 88 63 14.4 16.4 16.2 15.5 15.8 SDSS_i 1.06 02:12 AGILE 362(-1036) 33 39 13.1 12.0 12.8 11.5 12.4 BG40 1.35 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 64 -12 16 297 (WNW) 1500 clear none 17:00 63 -10 8 298 (WNW) 1338 clear none 18:00 65 -9 18 269 (W) 1374 clear none 19:00 62 -13 11 268 (W) 1377 clear none 20:00 59 -16 8 305 (NW) 1513 clear none 21:00 57 -18 2 332 (NNW) 1459 clear none 22:00 58 -18 8 302 (WNW) 1603 clear none 23:00 59 -18 8 305 (NW) 1603 clear none 00:00 58 -18 9 312 (NW) 1620 clear none 01:00 58 -17 6 266 (W) 1694 clear none 02:00 58 -18 3 251 (WSW) 1465 clear none 03:00 56 -19 3 296 (WNW) 1441 clear none 04:00 57 -19 1 284 (WNW) 1439 mstly clr none 05:00 58 -17 1 139 (SE) 1561 mstly clr none Note: the wind was coming from the azimuth listed.
