APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday March 18, 2008 (MJD 54544) ---=== OBSERVING TEAM ===--- Howard Brewington (dayShift) Shannon Watters (observer) Elena Malanushenko (observer) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We took imager QE calibrations for chips u2 and u3. Plate 2459 cart 2 has been observed. It is obtained some signal, possible good to declate this plate "DONE", but we ask an evaluation from BY as Sos failed to provide feedback. ---=== OBSERVING LOG ===--- Afternoon: ---------- The spectro focus was checked and adjusted; it's set for about 0.0 degrees C. The pre-adjusted spectro numbers via collimate are posted in the Problems Section. The disk space at /data and /files was good; see below: Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 126G 8.7G 94% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 573G 298G 66% /data sdssfiles1:/data1/data 1.5T 525G 869G 38% /files iccSoundOff responded that all crates were available; see Problems Section for command's output. 23:15Z Opened doors/louvers and turned on fans. Night: ------ We do not have any evening plates availble for observations with 94% of Moon illimination. We took imager QE calibrations for chips u2 and u3. We are using the "old" stageX values from now on (after talking to Mamoru and Masayuki) so we did u2 over again with the "old" value. The MSP log has been sent. Run 7375 02:05Z Frame 1 - MSP Bias 02:09Z QE for u 2 - First exposure; Frame 2: idR-7375-u2-2.fit - Last exposure; Frame 32: idR-7375-u2-32.fit 04:06Z QE for u 3 - First exposure - Frame 33: idR-7375-u3-u3-33.fit - Last exposure - Frame 64: idR-7375-u3-64.fit We took these measurements while ventilating the telescope with a nearly full moon. Checked bias and dark versus those from same chip from the last msp run and the pixel values are virtually equivalent. 06:30 Z We opened the enclosure. Cart 2 plate 2459 is mounted. Used fk5 and spiral pattern to find Guider Stars. T=-1.C, and foc=150, seeing 1.5", efficiency 80-85%. We are waiting for time to start this plate. 07:24Z preCalibration 07:38Z science 1200 08:01Z science 1200 08:24Z science 1200 08:47 preCalibration 09:01Z science 1200 -> 1500 09:29 science 1500 09:57 preCalibs 10:04 science 1500 10:32 science 1500 11:00 preCalibs 11:07 science 1500 11:35 science 1500 12:03 postCal This plate is obtained some signal, possible good to declate this plate "DONE", but we ask evaluation from BY as Sos failed to provide feedback.
