Seeing was horrible first half bouncing mostly from 2” to 3”. Second half seeing vastly improved once the dust levels dropped, ~1.0" at times. NA2 guider seemed to be guiding fine. We did not sit on any object for a very long time tonight, but nothing obvious was misbehaving. Twice in a row (~5 mins apart on the same object) we had rotator controller failures. It did not seem like we were in a bad position (Az 65, Alt 58, Rot 21). Here is the log output for the first error: 05:49:47 .tcc.0 0 tcc F Modu="prt_Read"; Text="read timed out on port LTA5:" 05:49:47 .hub 0 cmds i CmdDone=54051 05:49:47 .hub 0 cmds i NewCmd=54566; CmdTime=1207979387.36; Cmdr=".tcc"; CmdrMID=0; CmdrCID=".tcc.0"; CmdActor="tcc"; CmdText="" 05:49:47 .tcc.0 0 tcc I Modu="prt_Read"; Text="read: ROT STATUS" 05:49:47 .tcc.0 0 tcc I TCCStatus="TTT","NNN"; TCCPos=66.043,57.471,20.934; AxePos=66.061,57.460,20.926 05:49:47 .tcc.0 0 tcc W RotStat=NaN,NaN,NaN,NaN; RotDTime=NaN; RotID=1,0 05:49:47 .tcc.0 0 tcc I SpiderInstAng=52.936197,-0.002656,4714696227.75000 05:49:49 .tcc.0 0 tcc W Expected="ROT MOVE 20.9405756 0.0005484 21032.75000" 05:49:49 .tcc.0 0 tcc W Received=" " 05:49:49 .tcc.0 0 tcc F Modu="prt_ReadMatch"; Text="bad reply" 05:49:49 .hub 0 cmds i CmdDone=54566 05:49:49 .hub 0 cmds i NewCmd=54567; CmdTime=1207979389.18; Cmdr=".tcc"; CmdrMID=0; CmdrCID=".tcc.0"; CmdActor="tcc"; CmdText="" 05:49:49 .tcc.0 0 tcc F Text="failed to move one or more axes"; AxisNoTrack="FFT"; AxisErrCode="OK","OK","ControllerErr" 05:49:49 .hub 0 cmds i CmdDone=54567 05:49:49 .hub 0 cmds i NewCmd=54568; CmdTime=1207979389.2; Cmdr="MN01.telmech-mon"; CmdrMID=1349; CmdrCID="MN01.telmech-mon"; CmdActor="telmech"; CmdText="status shutters" 05:49:49 .hub 0 cmds i NewCmd=54569; CmdTime=1207979389.32; Cmdr=".tcc"; CmdrMID=0; CmdrCID=".tcc.0"; CmdActor="tcc"; CmdText="" 05:49:49 .tcc.0 0 tcc W Expected="ROT MOVE" 05:49:49 MN01.telmech-mon 1349 telmech i device=shutters; right=open; left=open 05:49:49 .tcc.0 0 tcc W Received=".9405756 0.0005484 21032.75000" 05:49:49 MN01.telmech-mon 1349 telmech : 05:49:49 .hub 0 cmds i CmdDone=54568 05:49:49 .tcc.0 0 tcc F Modu="prt_ReadMatch"; Text="bad reply" 05:49:49 .hub 0 cmds i CmdDone=54569 05:49:49 .hub 0 cmds i NewCmd=54570; CmdTime=1207979389.36; Cmdr=".tcc"; CmdrMID=0; CmdrCID=".tcc.0"; CmdActor="tcc"; CmdText="" 05:49:49 .tcc.0 0 tcc W Text="failed to stop one or more axes; will try init"; AxisNoSlew="FFT"; AxisErrCode="HaltRequested","HaltRequested","ControllerErr" 05:49:49 .tcc.0 0 tcc I Modu="axe_o_Init"; Text="locking ports: Az , Alt, Rot" 05:49:49 .tcc.0 0 tcc I Modu="axe_o_Init"; Text="initializing: Az , Alt, Rot" ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- UV03 S T/H 23:49 23:59 Rotator controller error ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM ----------------------------------------------------------------- 19:32 SPICAM 195( 250) 71 26 2.3 3.0 1.4 2.3 2.2 H6629 3.33 19:54 SPICAM 239( 262) 67 31 1.8 2.6 1.4 1.7 1.7 r 2.70 22:00 SPICAM 163( 44) 34 52 -0.4 0.3 0.5 -0.3 -0.0 r 3.10 23:16 SPICAM 116( -99) 3 57 -2.4 -1.5 -0.5 -2.5 -2.4 r 1.30 01:05 SPICAM 131(-161) 161 71 -3.8 -2.9 -1.4 -3.6 -3.7 i 1.57 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------- 16:00 40 0 22 300 (WNW) 1363 clear none 17:00 40 0 18 276 (W) 1414 clear none 18:00 41 -1 15 260 (W) 1418 clear none 19:00 39 -2 20 295 (WNW) 1447 clear none 20:00 37 -4 12 339 (NNW) 1908 clear none 21:00 35 -2 13 343 (NNW) 2243 clear none 22:00 34 -3 13 26 (NNE) 2399 clear none 23:00 31 -3 23 17 (NNE) 2251 clear dust 00:00 28 0 21 23 (NNE) 2886 clear dust 01:00 27 0 18 12 (NNE) 2501 clear dust 02:00 25 0 9 2 (N) 2116 clear none 03:00 24 0 4 18 (NNE) 1809 clear none 04:00 23 -3 8 329 (NNW) 1583 clear none 05:00 21 1 9 4 (N) 1421 clear none Note: the wind was coming from the azimuth listed.
