Echelle inter-order data set taken. Echelle fill times and temps looked good at 20:30 Training on new mirror move commands and git repository I worked on making corrections to the past couple of months of 3.5m night logs. I read the weight on the LN2 for the Echelle, I did not fill, at 20:30 @ 271#. This morning at 05:00 the weight was 260#. This was less than I had expected, around 250-245#. Maybe it had just finished filling at 20:30 and was about to start another soon? I did a fill time check just to be sure things looked like they were filling. 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle i TDStxt="# 4 FILLS SINCE DATA WAS LAST COLLECTED" 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle i TDStxt="# FILLTIME SECONDS" 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle i TDStxt="FILL_1_DEWAR_1 294 " 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle i TDStxt="FILL_1_DEWAR_2 209 " 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle i TDStxt="FILL_2_DEWAR_1 429 " 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle i TDStxt="FILL_2_DEWAR_2 224 " 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle i TDStxt="FILL_3_DEWAR_1 394 " 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle i TDStxt="FILL_3_DEWAR_2 219 " 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle i TDStxt="FILL_4_DEWAR_1 394 " 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle i TDStxt="FILL_4_DEWAR_2 219 " 2014-08-15 11:00:00 APO.Jack-Obs1 119 echelle : TDStxt="" I am not sure what "normal" times are for Dewar 1 to fill.

Maybe I just misread the weight or something at the start of the night. Might not be a bad idea to keep an eye on things today though. ------- 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 -------------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 61 53 3 325 (NW) 657 cloudy none 17:00 62 51 2 332 (NNW) 510 cloudy lt rain 18:00 62 52 6 256 (WSW) 502 cloudy rain 19:00 55 52 8 134 (SE) 872 cloudy lt rain 20:00 55 53 8 118 (ESE) 1098 cloudy humid 21:00 56 53 6 179 (S) 706 cloudy humid 22:00 57 52 2 207 (SSW) 636 cloudy humid 23:00 56 52 7 204 (SSW) 617 cloudy humid 00:00 55 53 7 206 (SSW) 886 cloudy humid 01:00 54 53 11 211 (SSW) 1109 cloudy fog 02:00 54 52 5 243 (WSW) 778 cloudy humid 03:00 56 49 6 236 (SW) 581 cloudy none 04:00 57 49 4 264 (W) 464 cloudy none 05:00 59 44 3 280 (W) 345 cloudy none Note: the wind was coming from the azimuth listed.
