APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday December 6, 2002 (MJD 52615) ---=== OBSERVING TEAM ===--- Mike Harvanek(by day) Scot Kleinman Atsuko Nitta ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Lots of troubles, but we finished three plates and got around 20deg of 14N scans. Some signs the red sky may be back? We lost significant time having to re-collimate the spectrographs during the night and landru's X server froze once, only to allow us to all but recover when all of landru crashed and would not come back up. It is now powered down with some disk errors an expert will need to look at (Craig?). Cloudy the first part of the night, then bad seeing, then good enough seeing for a last hour or so of imaging. ---=== OBSERVING LOG ===--- Scattered clouds at twilight. We started with cart 7 plate 1143 (rockosi). We took our time setting up, starting the first science exposure ~8m before twilight. Clouds kept the first 20m exposure from being useful, so we changed the second exposure to 30m, but had some trouble doing so (see problems) although it eventually worked. We got no good exposures on this plate before it expired and went to cart 4, plate 1126 (munn) next. We had a fiducial too large to correct in altitude on the instChange command. See problems. Our first 30m exposure on this plate 1126) resulted in blue (S/N)^2 ~7 and red, ~2-3. SoS-reported sky/sec gave red values ~3X those of the blue. We used idlspec2d's apoplotsky (thanks David - works nicely) to verify that the red sky indeed appeared higher than average. We still don't have a good set of good and bad sky plots for comparison, but comparing to the ones Connie posted to sdss-obs sometime back (and assuming her units are correct; she was concerned about that), exposure 17287's 6305 angstrom feature was HUGE compared to Connie's old plot and the other features were factors of 2-5 higher than in her base comparison and similar ot those seen earlier this season. If the red skies are back - what can we do about them? However, we got no warnings or messages from SoS for this exposure, so maybe the comparisons aren't good. We tried to use apoplotsky to look at older data, but could not find any that were still stored on SoS (I believe this may be due to an rsynch problem caused by the change to the new SoS, but then that doesn't quite make sense since SoS has been reducing data. Hmmmmm.). We took a smear exposure on this plate in clouds. Next up: cart 1 plate 809 (photoz). After the first exposure, we saw that we had missed SoS complaining about our collimation, so we stopped to re-collimate and declared the previous science exposure bad. We had to move the sp1 piston by -4997 and -1285 and sp2 by -5836 and -1163. We moved b1 by ~5.3 degrees and b2 by ~8.4 degrees. B1's locking ring was difficult to move. We had to run goSpecFocus 3 times to get collimated. The last Hartmann exposure, SoS reported a good Wsigma of 0.98. For the post-"in collimation check" arc, we got a yelow Wsigma of 1.08, yet collimate said everyhing was VERY close to optimal spec. Our next arc was OK. By the time collimation was done and checked, the plate was almost expired, so off to cart 9, plate 894 (science). No GSOTGTF for this plate; an fk5 star was ~7" away. Around this time, the clouds disappeared, but the wind picked up and the seeing got a lot worse: 2"+. We finished this plate (woohoo), got a good smear and went off to cart 3, plate 961 (standard science). I noticed tonight that after observing the cartridge without a guider fiber #3 earlier in the night, future cartridges showed "in use: no" for that fiber in the guiderDataWindow, although the "okay" and "fibers used": sections sowed fiber 3 was GOOD and active. So, where's the bug - is it in the "in use" display, or is something weird going on with a once-bypassedd guider fiber? We ran out of plates. The sky was photometric, but seeing not good, but we decided to try imaging anyhow since we figured the reward there was greater than pounding away at this plate and there was some chance of success. Run 3518 14N ------------- We started imaging 14N. Our gamble paid off. Son-of-Kent reported that the seeing was good from the beginning of the run. We were in focus by frame 13. Shrotly thereafter, landru's X server went on the fritz and logged me out completely. I got it going again by doing a kill -HUP on it. However, once logged back in and 3/4 back towards gettign things under control again, landru crashed hard and came up with some weird fsck errors I could not fix. At this moment, landru is truned off and needs expert assistance to revive. During all this mess, the teamster died, perhaps multiple times. This, and the sudden logouts from IOP caused a dealy in us getting skippy results. Although the seeing and rotator was in-spec, the nuErr was large. It started out at 16". (There were no fiducial corrections that was too large when we went to the field and offsets from spectroscopy were cleared at the start of the imaging slew.) The teamster died again (because Scot's iop session which started the teamster died?) sometime after transferring frame 45, but before getting to frame 50. By the time we found out that nuErr was large from the beginning, we were already less than an hour before twilight. So we decided to keep on taking data rather than stop the run and repoint (we were in spec, besides- just, but the right side of just). BTW, the early skippy entry was lost when Scot's iop session on Landru died because he had the control of the log. We kept a close eye on the nuErr and ran skippy frequently; it remained below 18". Note, we did not see the ~0.01 rotator offset we saw last night. Last good science frame 149, lambda=-22.26 We took donuts in twilight. Frame 149 in-focus Frame 154 +300 out-of-focus Frame 157 -300 out-of-focus After all this, we actually remembered to get a bias run as well and endNight finished successfully (which we saw since we needed to stay up for twilight PT flats.) ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame
