APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday September 8, 2006 (MJD 53987) ---=== OBSERVING TEAM ===--- Steph Snedden Jian Ge (UF) Pangcheng Guo (UF) Support: French Leger (by phone) Wendell Jordan (by phone) Mike Harvanek (sanity checker) Visitors: Elena Malanushenko Jurek Krzesinski ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- You guessed it. Clouds and rain followed by high humidity. No science. ---=== OBSERVING LOG ===--- Afternoon: ---------- During afternoon checkout I found I could not initialize the rot and alt axes for motion (az was okay). Looking at the root cause in the interlocks display showed a green status for the spectro_autofill_on, however the hoses were disconnected. French was called. It turns out Wendell had replaced the autofill circuit board with a spare that did not support the interlock logic. Over the phone French described the location of the connector to that part of the board and asked that I short out the two pins there. That did the trick. For the weekend, we can work with the connector shorted. If the telescope shows the same symptoms over the weekend, the first thing to do is check that the wire shorting the female end of the connector on the autofill control box is still taped securely in place. On a related note, manual spectro fills still need to be done every twelve hours. This will continue at least through the weekend. Night: ------ 04:00Z - Heavy rain. The building fire alarm went off, complaining about the new dorm first, then the operations building attic. No fires noted. Alarm was silenced. 05:00Z - The rains end, but high humidity remains. 11:38Z - High humidity still. We give up. endNight rejoices. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- a doghoude bias was done, but before I started logTool. ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n):n QA Procedures Done (y/n):n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 02:46Z 49 48 7 266 (W) 432 - Cloudy 03:18Z 50 49 4 267 (W) 433 - ' 03:51Z 49 49 3 220 (SW) 794 - Rain 04:23Z 47 47 7 176 (S) 6834 - ' 04:55Z 46 47 4 82 (E) 1507 - Cloudy 05:27Z 48 46 4 268 (W) 174 - ' 05:59Z 48 46 8 268 (W) 167 - ' 06:31Z 48 48 7 262 (W) 343 - ' 07:04Z 48 47 5 253 (WSW) 273 - ' 07:36Z 48 48 6 234 (SW) 3077 - Fog 08:08Z 48 47 2 252 (WSW) 316 - ' 08:40Z 48 47 3 275 (W) 720 - ' 09:12Z 48 48 5 274 (W) 639 - ' 09:44Z 48 48 1 301 (WNW) 80301 - ' 10:16Z 48 48 5 336 (NNW) 29806 - ' 10:49Z 48 48 5 343 (NNW) 437 - ' 11:21Z 47 47 6 333 (NNW) 329 - ' ---=== TELESCOPE STATUS ===--- Never opened, never ventilated. 08:17Z - Spectro manual fill made. 11:43Z - A short manual fill made to top off the dewars (in case I oversleep).
