Local network problems started at around 16:40 tonight. We lost connectivity (first wifi, then both wifi and ethernet). It was up and down for the next couple of hours. This seemed to only affect us locally with DHCP addresses and not my remote observers connection. Pesky clouds causes several breaks in observing during the first half tonight. 2nd half needed the NA2 guider camera and it now had a no route to host. I had to power cycle the computer on the IL to recover as it was non-responsive to pings. A rather breezy night and the system to our SE gave us rather poor seeing, especially 2nd half. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:26 ecamera 474( 587) 214 77 15.8 17.4 17.4 17.3 15.9 clear 1.43 21:12 ecamera 524( 554) 248 74 15.7 15.7 16.2 15.4 15.4 ND2 1.29 01:17 NICFPS 427( 1751) 56 35 10.3 10.7 11.6 10.6 10.1 H2-2.12 1.36 02:51 NICFPS 311( 1565) 30 49 9.2 9.5 10.4 9.3 9.2 H2-2.12 1.97 02:52 NA2gdr 1060(49060) 30 49 9.3 9.4 10.3 9.2 9.2 clear 2.37 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 71 20 15 208 (SSW) 1061 ptly cldy none 17:00 72 20 32 235 (SW) 1726 ptly cldy none 18:00 67 16 24 256 (WSW) 3795 mstly clr none 19:00 64 15 30 267 (W) 2598 clear none 20:00 61 13 19 256 (WSW) 2095 mstly clr none 21:00 60 14 22 265 (W) 1369 ptly cldy none 22:00 58 15 17 267 (W) 1357 ptly cldy none 23:00 56 17 15 270 (W) 1852 mstly cldy none 00:00 53 19 18 288 (WNW) 2407 mstly cldy none 01:00 51 25 21 311 (NW) 2078 ptly cldy none 02:00 50 27 17 270 (W) 1519 mstly clr none 03:00 49 25 17 298 (WNW) 1442 clear none 04:00 48 25 18 301 (WNW) 1420 clear none 05:00 46 24 19 308 (NW) 1320 clear none 06:00 46 25 18 332 (NNW) 1078 clear none Note: the wind was coming from the azimuth listed.
