Files stopped transfering automatically. They restarted TUI to see if that would fix the issue. Data we being written to our servers, so nothing was lost. Images were 60s exposures, so I don't think it was some sort of data backlog issue. The observer said it happend 3 days ago as well. Restarting TUI seemed to fix the issue. The observer was observing from their appartment in Japan with poor internet. It happened again later in the night, we think it was an internet connectivity issue. The data stopped again while taking darks at the end of the night. ------- 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 -------------------------------------------------------------------------- 18:38 arctic 543( 1080) 56 84 4.6 6.2 5.5 5.8 6.2 SDSS_g 0.85 18:40 NA2gdr 5001(39001) 53 84 4.7 6.2 5.5 5.7 6.1 clear 1.00 01:07 APOLLO 385( 1454) 31 72 4.4 2.0 3.8 3.2 3.3 530 1.10 02:49 arctic 409( 798) -166 69 4.2 3.1 3.7 3.2 3.4 SDSS_i 0.80 02:51 NA2gdr 1661(35661) -165 69 4.2 3.0 3.7 3.1 3.3 clear 1.22 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 39 12 1 204 (SSW) 2441 clear none 17:00 40 13 5 164 (SSE) 1643 clear none 18:00 40 11 4 187 (S) 868 clear none 19:00 39 10 6 181 (S) 783 clear none 20:00 42 1 6 187 (S) 365 clear none 21:00 41 5 8 191 (S) 384 clear none 22:00 40 9 7 185 (S) 645 clear none 23:00 40 11 10 183 (S) 815 clear none 00:00 40 12 11 185 (S) 1017 clear none 01:00 39 15 13 200 (SSW) 1314 clear none 02:00 40 14 14 195 (SSW) 1056 mstly clr none 03:00 41 16 13 190 (S) 985 mstly clr none 04:00 40 18 20 208 (SSW) 944 mstly clr none 05:00 40 20 14 218 (SW) 1124 ptly cldy none 06:00 38 28 16 205 (SSW) 1353 ptly cldy none Note: the wind was coming from the azimuth listed.
