APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday November 18, 2003 (MJD 52962) ---=== OBSERVING TEAM ===--- Atsuko Kleinman (swing) Mike Harvanek Dan Long Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Imaging: 82 N from lambda = +160 to -175.8 with some patches of bad seeing. Still acceptable data worth reducing in our judgement. Apache wheel: Rim scan, RA 330 to 97 Spokes 45 and 60, both long Spectroscopy: Three plates finished (1255, 1585, 1296). Photometric all night. Some of the most transparent and cleanest air ever seen on the mountain. Both the met tower and the 3.5m enclosure 1.0u dust sensors were reading 0 at the same time for a while and both were reading in the single digits multiple times during the night. ---=== OBSERVING LOG ===--- Afternoon: --------- Due to the work to fix the leak on the west enclosure door, the telescope was out in the open until around 2pm (21Z). Spectro focus: collimate said to change coll.motor positions, but I was not sure if this is caused by the fact that the telescope was outside today. The air temp at the time I took hartmann exposures were close to 0C, the enclosure ambient was around 6C. I do not know if the isntruments are around the air temperature, or slightly cooler/warmer. Since I suspect the spectros need focus adjustments mainly due to the exposure to the sun today, I decided not to change the coll. positions and asked Dan and Mike that they might need to adjust during the night. Everything else checked out fine. Night: ------ Photometric and moonless so we began with imaging. Run 4252, 82 N: Seeing was bad. When the mirrors finally came into thermal equilibrium the seeing became acceptable. At this point we terminated this run and started over at the beginning of the strip. Run 4253, 82 N: Pointing, focus and seeing all good/acceptable from the start (lambda +160). seeingRun reported 3 patches of bad seeing but appeared to be a bit overzealous in its judgement. We believe the seeing was bad during frames 23 - 33 (lambda 161.8 - 163.3), frames 104 - 114 (lambda 173.9 - 175.4) and frame 173 (lambda -175.8) and beyond. There may also be some contamination from car headlights in frames 76 - 77. Even with the problems mentioned above, we still think this run is acceptable and is worth reducing. Switched to Apache Wheel because of bad seeing. The 1st attempt at a binned scan caused Dan's iop to crash back to the sdsshost prompt. All screens went blue except for ad4 (which is normally seen in this failure mode). Some investigation showed no ptvme errors and the servers did not die (both of which are unusual). Furthermore, Dan was able to start another iop (also unusual). After starting another iop, a 2nd attempt at a binned scan was made and was successful. No rebooting of the crates was necessary but in order to start the 2nd scan it was necessary to clear daqBusy on the imager with a readoutAbort. Run 4256, Apache Wheel: rim scan starts at frame 12, RA 330. rim scan ends at frame 432, RA 97. Dan believes he has figured out why we are now filling tapes when we do Apache Wheel. The frame length appears to be 1/4 of what it should be. So, we ended this drift when the rim scan ended and adjusted the frame length in an effort to test his hypothesis. Changing the command init4Bin 4 4 16050 to init4Bin 4 4 16050 -keepSize seems to have solved the problem because we did not fill tapes tonight. Could someone (Connie?) please verify that this change is correct. If it is correct, we need to make a change to the apache wheel observing procedure. Run 4257, Apache Wheel: spoke 45 good from frame 10, DEC = -22. spoke 45 ends at frame 57, DEC = +86 (past the pole). spoke 60 good from frame 60, DEC = -23.5. spoke 60 moonrise at frame 103, DEC = +80. spoke 60 ends at frame 109, DEC = +85 (past the pole). Since we did not have time to do a hub scan we decided to connect spoke 60 with spoke 45 by bringing spoke 60 past the pole as well (i.e., both spoke 45 and spoke 60 are long spokes). Note that the last 6 frames of spoke 60 were obtained after moonrise. After moonrise we switched to spectroscopy. Counterweight 4 squeaked loudly during movement. Plate 1255 (cartridge 4): An FK5 was needed to acquire the field and the offsets were substantial (19"E, 11"N). When combined with previous data (52946, 52959), this plate was done in 1 exposure (1200 s). Got the following watcher errors during this plate: dsc E trcErr WRONG num of pix?? for (sr<<16)|ccd:0x00000001 rowIdx:0 (dsc_E_trcErr WRONG num of pix?? for (sr<<16)|ccd:0x00000001 rowIdx:0 : 2003-11-19 09:47:26Z ) dsc E trcErr WRONG num of pix?? 2126 should be 2128 (dsc_E_trcErr WRONG num of pix?? 2126 should be 2128 : 2003-11-19 09:47:26Z ) dsc E trcErr WRONG num of pix?? for (sr<<16)|ccd:0x00000000 rowIdx:0 (dsc_E_trcErr WRONG num of pix?? for (sr<<16)|ccd:0x00000000 rowIdx:0 : 2003-11-19 09:47:26Z ) Plate 1585 (cartridge 8): Guide stars after previous offsets were cleared. When combined with previous data (52945), this plate was done in 2 exposures (1800 s total).

When combined with previous data (52959), this plate was done in 3 exposures (2700 s total). When closing, we noticed that the door to the azimuth junction box (on the chiller rack) was open and there were wires hanging out of the box. Is this supposed to be like this? endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame
