One of the WY02 observers had issues downloading images. Error message: Download failed: invalid command name "::http::geturl" Tried following wiki instructions on a similar sounding issue. Tried ssh'ing into tron@hven to add their IP address to an allowed list, but ssh just timed out, so was not able to resolve the issue for them. Other observers were able to download fine. Cloudy night with high humidity throughout kept us closed all night. Clouds eventually cleared by the end of the night, but humidity stayed uncomfortably high. ------- 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 -------------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 46 42 2 89 (E) ptly cldy humid 17:00 45 42 12 55 (NE) cloudy humid 18:00 43 41 15 81 (E) cloudy humid 19:00 42 41 16 77 (ENE) cloudy humid 20:00 43 42 14 65 (ENE) cloudy humid 21:00 43 42 12 78 (ENE) cloudy humid 22:00 43 42 12 60 (ENE) cloudy humid 23:00 42 42 18 73 (ENE) cloudy humid 00:00 42 41 11 87 (E) cloudy humid 01:00 42 42 16 76 (ENE) cloudy humid 02:00 42 42 11 78 (ENE) cloudy humid 03:00 43 42 7 108 (ESE) cloudy humid 04:00 43 41 9 84 (E) mstly cldy humid 05:00 44 41 7 127 (SE) clear humid Note: the wind was coming from the azimuth listed.
