Opened enclosure at 2050. Closed enclosure at 2230. A short thunderstorm brought rain at 2328. We closed the cloudcam, closed louvers and shutoff the enclosure fans. 2nd Half Observing Specialist: J.

Skies cleared up nicely after this and stayed that way for the remainder of the night. ------- FAILURE LOG ------- PROG INST FAILURE TIME S/E/G/D/O TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 21:24 GFP -50(964) 212 70 12.6/13.2 278 6 6717 1.28 02:05 GFP -50(875) 81 69 10.4/11.4 44 11 6717 1.50 --------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 59 42 16 266 (W) 233 Prtly Cldy None 17:01 57 45 14 290 (WNW) 369 Prtly Cldy None 18:01 58 45 8 274 (W) 297 Prtly Cldy None 19:01 55 44 5 294 (WNW) 337 Prtly Cldy None 20:01 55 43 6 276 (W) 320 Overcast None 21:01 53 43 7 270 (W) 353 Prtly Cldy None 22:01 55 40 7 275 (W) 404 Mstly Cldy None 23:01 53 43 9 10 (N) 367 Overcast Rain 00:01 47 43 12 26 (NNE) 297 Pt.
