APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday February 26, 2005 (MJD 53428) ---=== OBSERVING TEAM ===--- Swing: Howard Brewington ---=== OBSERVING PLAN ===--- Monthly Checkout ---=== OBSERVING SUMMARY ===--- ---== Monthly checkout ==--- For some reason, Watcher declared a few windScreen touches tonight while the telescope was at the stow position. While doing a mechPiston, as part of Spectro focus, coll_motor_B and/or C did not move on Sp2; see log for details. I got an guideCam error in sop while dong a preCal; see log. Had to restart the servers (start_servers -K) because two on the server windows crashed. I was unable to completed the Dithered Flat procedure because of errors with respect to coll_motors movement; see log for error message. I had a similar problem earlier in the night with a mechPiston command. Watcher reported many errors of wrong # of pixels; see message below: dsc E trcErr WRONG num of pix?? for (sr<<16)|ccd:0x00000000 rowIdx:1 (dsc_E_trcErr WRONG num of pix?? for (sr<<16)|ccd:0x00000000 rowIdx:1 : 2005-02-27 06:35:01Z ) dsc E trcErr throttled 6 -- WRONG num of pix?? for (sr<<16)|ccd:0x0000000 (dsc_E_trcErr throttled 6 -- WRONG num of pix?? for (sr<<16)|ccd:0x0000000 : 2005-02-27 6:35:01Z ) dsc E trcErr throttled 6 -- WRONG num of pix?? 0 should be 2128 (dsc_E_trcErr throttled 6 -- WRONG num of pix?? 0 should be 2128 : 2005-02-27 06:35:01Z ) ---=== OBSERVING LOG ===--- Found a few bias-frames in /data/lostSpectroFrames on sdssHost, which were RMed. As described in the Log File Maintenance procedure, I checked the disc space of /d4/mcptpm on sdssHost. It was not tight, so I did not scp any files to /mcptpm on sdssCommish. I did notice, however, that these two directories shared many of the same MJD's. Checked other various directories for proper space, e.g., /data/photo, /data/astro, /data/mt, and so on. All were okay. I noticed that the Wind Speed on Galileo/displayweath was displayed such as 6.677579857365345356.0 Spectro focus numbers are in the Problems Section of log. --== Spectro Monthly Checlout ==--- I was able to ventilate the 2.5m enclosure for about one-hour before high humidity became a problem. Unfortunately, the telescope never completely reached equilibrium. Small adjustments were made to XMIN/XMAX and WAVEMIN/WAVEMAX. Before doing a goSpecFocus, I did a preCal and got the following error message that indicated the guider was unhappy. sp1> SOPGUI: preCalibs 1 1 mcpPut: SYSTEM.STATUS mcpPut: SYSTEM.STATUS Closing Flat Field Screen 4 FF lamps are on Image Size is 384 by 256 (should be 768 x 512) loading /data/spectro/guiderDarks/dark-20-53385.fits Error: GMAKEHIST: Flat exposure is too faint. Counts in fibers must be > 500 sp1> ****** Seems the guide camera was unhappy, but I did not know how to reset the image size. So, I used a postCal, which does not do a guider flat, to complete the goSpecFocus procedure. After goSpecFocus, I did a mechPiston for both Spectros. For some reason, coll_motor_B and/or C for sp2 did not move properly, so I reset all the motors and tried. This time motor_C moved okay. sp1> sp2 sp2 sp2> mechSend s spMechVersion v2_6_0 Bootup 793817973 SpectroID 2 SlitID 3 Air On Shutter_open_sensor Off Shutter_closed_sensor On Left_open_sensor Off Left_closed_sensor On Right_open_sensor Off Right_closed_sensor On Coll_motor_A 2701 Coll_motor_B -1312 Coll_motor_C -700 Requested_exp.time 0 Exp_time_left 0 Last_exp.time 0 Humidity 0 Temp_Median 6 Temp_Hartmann_Bot 6 Temp_Hartmann_Top 6 Temp_Red_Cam_Bot 6 Temp_Red_Cam_Top 6 Temp_Blue_Cam_Bot 6 Temp_Blue_Cam_Top 6 AD 1792 1094 sp2> mechPiston 3602 2005-02-27 02:27:42Z: Original command was !mb1000! 2005-02-27 02:27:42Z: expected reply was !mb1000 OK ! motor b: Mechanicals did not respond correctly; response was mb1000 Error: problem with motors (see previous error message) Original motor positions: {a 2701} {b -1312} {c -700} Current motor positions: {a 6303} {b -257} {c -700} sp2> mechSend s spMechVersion v2_6_0 Bootup 793817973 SpectroID 2 SlitID 3 Air On Shutter_open_sensor Off Shutter_closed_sensor On Left_open_sensor Off Left_closed_sensor On Right_open_sensor Off Right_closed_sensor On Coll_motor_A 6303 Coll_motor_B -257 Coll_motor_C -700 --== Dithered Spectro Flats ==-- As with mechPiston, there was another problem with the coll_motors during the dithered flat procedure. See error below. Consequently, I did get the dither flats done. Finished with specFlat 4 of 7.
