APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday January 25, 2006 (MJD 53761) ---=== OBSERVING TEAM ===--- Swing: K. Pan Night: M. Harvanek, H. Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- High wind, high humidity, clouds. Never opened. ---=== OBSERVING LOG ===--- Afternoon: ---------- During the afternoon checkup, I noticed PT moved by less than a half degree just after the driver and Motors being enabled. This is the second consecutive day, I noticed the small movement. The pressure of spectrograph dewar (dewar # 7) was found low at 14 psi. Then it was increased to 25 psi by openning the pressure building valve, but it gradually decreased to about 18.5 psi, and seems stable for a while. Is there any leakeage? can somebody check it, please. Spectrograph focus checked, no change made. The best focus is still at about 1 C. As usual, details in problem section. No ventilating because of snowing. Night: ------ High wind, high humidity, clouds. Never opened. Mike had problems with logTool tonight. His logTool would not load the previous activity (time tracking) section. He redid the section and all is correct. This happened when he was running as himself and as observer. We suspect the problem may be due to the fact that he runs .cshrc rather than .bashrc. He'll talk to Jon Brinkmann or Fritz Stauffer about the problem. With the humidity at 93%, the sky totally overcast and the satellite images showing a huge wall of clouds, we called it at around 11:15Z. endNight finished successfully. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5993 22:46Z 23:05Z 100 O -184.10 -179.43 45 ignore ---=== 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): YES QA Procedures Done (y/n): NO UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 36712, plate -9999 ------- 23:05 36712 0.0 bias 23:07 36713 0.0 bias ----- sequence 36714, plate 2379 ------- 23:14 36714 10.0 flat 23:16 36715 2.0 arc 23:20 36716 2.1 arc 23:23 36717 2.1 arc ----- sequence 36718, plate -9999 ------- 01:08 36718 0.0 bias 02:36 36719 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== 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 22:41Z 33 29 31 152 (SSE) 1064 - 23:12Z 33 27 26 132 (SE) 1131 - 23:43Z 35 29 30 146 (SE) 917 - 00:14Z 35 28 28 133 (SE) 902 - partly cloudy 00:38Z 35 29 35 139 (SE) 1116 - 01:10Z 34 28 28 146 (SE) 1169 - 01:42Z 33 27 28 152 (SSE) 1233 - 02:16Z 33 27 31 145 (SE) 1226 - 03:28Z 34 32 21 174 (S) 828 - 03:59Z 34 32 34 170 (S) 715 - 04:30Z 34 33 26 158 (SSE) 773 - 05:01Z 33 32 24 153 (SSE) 877 - 05:31Z 32 32 25 156 (SSE) 1078 - 06:02Z 32 31 25 161 (SSE) 1144 - 06:33Z 35 32 27 164 (SSE) 1383 - 07:04Z 34 32 28 178 (S) 1355 - 07:35Z 37 29 25 200 (SSW) 1311 - 08:06Z 36 31 19 187 (S) 1558 - 08:36Z 36 31 19 189 (S) 2241 - cloudy 09:06Z 35 31 25 190 (S) 1750 - 09:36Z 35 32 19 204 (SSW) 1538 - 10:06Z 34 32 23 194 (SSW) 1580 - 10:37Z 34 32 12 193 (SSW) 1618 - 11:07Z 35 33 22 201 (SSW) 1779 - ---=== TELESCOPE STATUS ===--- Never opened - wind, humidity, clouds.
