I should have known that was a bad sign. The night started with a few stray clouds but the winds were very high (+40mph) and the humidity never came down. We were able to open for a couple hours but the clouds stayed over where WY02 wanted to point. Given the wind was so high and the humidity was climbing, we decided to close. Things never improved and there was morning fog. No problems tonight. Happy Bastille Day! -------------- Stars... In your multitudes, Scarce to be counted, Filling the darkness, With order and light, You are the sentinels, Silent and sure, Keeping watch in the night, Keeping watch in the night... Look down, look down, Don't look up in the sky, Look down, look down, If this wind would only die... I know a place where no time's lost, I know a place where no sky cries, Crying at all is not allowed, Not in my castle on a cloud... I had a dream the obs would be, So different from this fog I'm living, So different now from what it seemed, Now clouds have killed the dream, I dreamed... There's a grief that can't be spoken, There's a pain goes on and on. Empty chips at empty tables, Now my obs are dead and gone Foggy faces at the window, Sleepy shadows on the floor, Empty fits at empty tables where your stars will meet no more. Oh WY, WY don't ask me, What your sacrifice was for, Empty fits and empty tables, To your field we slew no more. At the end of the day there's another day dawning, And the sun in the morning is waiting to rise. And the clouds crash towar' white sand, Like a storm that'll break any second... There's a hunger in the land, There's a galaxy still to be reckoned... And there's gonna be sleep to pay, At the end of the day! Do you hear the birdies sing? Singing the songs of angry obs? It is the music of the people, Who will not be slewed again! When the beating of your heart, Echoes the beating of the drums, There is a life about to start, When tomorrow comes! ------- 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 -------------------------------------------------------------------------- 20:23 tcamera 700( 1285) -65 35 11.7 13.0 13.6 12.8 12.5 -- 1.61 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 60 47 22 71 (ENE) 253 mstly clr none 17:00 61 44 16 113 (ESE) 322 mstly clr none 18:00 60 44 13 76 (ENE) 244 mstly clr none 19:00 58 46 18 64 (ENE) 250 mstly clr humid 20:00 55 47 22 87 (E) 158 ptly cldy humid 21:00 53 45 25 81 (E) 250 mstly cldy humid 22:00 53 46 30 72 (ENE) 504 mstly cldy humid 23:00 54 44 27 67 (ENE) 878 mstly cldy humid 00:00 52 47 31 74 (ENE) mstly cldy humid 01:00 51 32 30 71 (ENE) ptly cldy humid 02:00 51 31 17 84 (E) mstly clr humid 03:00 51 31 10 92 (E) ptly cldy humid 04:00 52 31 12 85 (E) mstly cldy humid 05:00 52 29 2 195 (SSW) mstly cldy humid 06:00 51 29 11 131 (SE) mstly cldy humid Note: the wind was coming from the azimuth listed.
