APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday August 18, 2009 (MJD 55062) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Elena Malanushenko kaike Pan Jon Brinkmann French Leger ---=== OBSERVING PLAN ===--- Engineering Night ---=== OBSERVING SUMMARY ===--- Continue engineering work with telescope. Telescope was moving very well. The secondary did not go to "home" position and French is going to check it. Fiducials tables was not installed as "az" table needs to mesure again. Dimm was working but shows bad seeing 2-3". ---=== OBSERVING LOG ===--- Telescope is moving and it is checked. The moving, fiducials crossing, lamps are ok. We need to adjust the balance very much after telescope reconstruction. New balance is on ~100 counts less then usual, and EngCan & Lens is good with 170 lbs. Moved telescope on alt=4 abd removed the cover. Images biases are normal. Dimm was working fine for us, seeing was 2-3". The windbuffel is not assembled completely yet and we had stronger requrement on wind less the 25 mph. The wind was arount it for whole night. We checked the new fiducials, "alt" and "rot" looks good, but "az" has several outliers. Besided that, the telescope was very warm at day time. French is going to re-build the tables tomorrow. We made "home/relax" for primary, and it worked fine for us. The "home" secondary did not work properly. Command A=0; B=0; C=0; XQ#HOME repeated several times gave random large errors. French found out that secondary did not go to home position after several attemptions and stay away from home. He will check it. We cannot proceed with optical collimation until secondary does not move properly. Spectro dewar is connected directly to sp2. We need to keep hose disconnected and connect it and fill the dewar manually every ~6 hours. Slowly disconnect the hose after filling to reduce the presure step by step. We filled it at 7pm and 11pm with French, and he will carry about them in the morning. The is the temporary solution. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 8003 23:52Z 00:09Z 100 O 34.69 38.95 43 bias ---=== 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): QA Procedures Done (y/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 22:45Z 74 41 14 259 (W) 989 - 23:17Z 67 39 10 265 (W) 1302 - 23:47Z 65 43 2 153 (SSE) 1716 - 00:20Z 59 47 2 94 (E) 2146 - 00:52Z 58 48 20 123 (ESE) 2356 - 01:24Z 57 46 13 121 (ESE) 1981 - 01:56Z 58 43 16 135 (SE) 1492 - 02:28Z 57 42 19 137 (SE) 1545 - 03:00Z 57 42 21 141 (SE) 1589 - 03:32Z 57 41 22 133 (SE) 1430 - 04:05Z 57 42 21 136 (SE) 1844 - 04:37Z 56 42 16 156 (SSE) 1798 - 05:17Z 57 41 11 175 (S) 1797 - 05:50Z 58 42 19 163 (SSE) 1769 - 06:22Z 58 41 14 155 (SSE) 1723 - ---=== TELESCOPE STATUS ===--- Dis not open.
