APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday April 16, 2004 (MJD 53112) ---=== OBSERVING TEAM ===--- Swing: Howard Brewington Night: Atsuko Nitta Pete Newman ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Fine spectro night. We finished 6 plates. The pointing was not too great as you can judge by the offset recorded in the offset section. We did not need to do more than one axis init after a stop button was released tonight. At sunset, Pete found Dewar #12 hissing. It turned out that the vacuum burst disk has broken. JB was notified and he transferred the remaining LN2 to another dewar and opened the vent valve. endNight did not run successuly at our first attempt due to permission problem on /mcptpm/MJD. PR was filed. We changed the permission of this directory and reran endNight. Ok, that did not work. Now we decided that Atsuko will run endNight (the last two times was run by Pete) and we will go to bed and not wait for it to complete. The data will be on the tapes 3 times......... ---=== OBSERVING LOG ===--- Swing: During an initNight -tapeLoad, id1-1 and 1d1-2 had read problems, so I rebooted the photo-one crate, which solved the problem. Spectro focus was checked and adjusted; see problems section for details. Night: With thin clouds overhead, we have to start with spectro. cart 8 plate 1617 -------------------- fk5ed since the sky was still still bright for the guide stars. fibers 9 10 look quite dirty. Could someone please have a look? Since we had a bit of time, we tried slewing to the field from east and west of the field to see if it makes any differences. We found no differences. 02:31Z After scaling change, we lost the guide stars and we had to fk5 to get the field back. Guider got confused with a large scale change (0.024)?? We tweaked the focus between the two science exposure. 03:25Z Craig walked into the control room to inform us that DIMM stopped measuring the seeing. CCD was no longer connected. Craig restarted the dimm software and it started to work again. Finished after 3 exposures. We did postCalib. The third science r2 exposure got the following warning in SoS. Looking at apoplotsky, the exposure below looked like it had slightly higher sky values (as indicated by the warning). Caused by thin clouds????? sdR-r1-00026106.fit: WARNING: Max sky-residual chi2 = 64.1559 at 8886.52 Ang (ignoring 5577) Cart 4 plate 1748 -------------------- Offsets from the previous plate did not work. We cleared offset and go to a fk5. We had to move ra=10", dec=12" to find the fk5 stars. After preCalib, the following came up when the starGuider was issued: 2004-04-17 04:27:11Z: registered (addr20) listener sdsshost:observer:20537 SOPGUI: startGuider 10 Using 10 second gcam exposures File /data/spectro/guider/ doesn't exist, isn't readable, or is a directory FIY, PID = 70876. The clouds changed the thickness during the observations and we went from 10s guider exposure time to 30s and then back to 10s. The r2 second science exposure got the similar sky-residual warning as we got for the last plate for r1: sdR-r2-00026112.fit: WARNING: Max sky-residual chi2 = 71.3282 at 8956.01 Ang (ignoring 5577) The FWHM for half of the guide fibers were giving exact same numbers for many of the exposures. The total number of counts are changing, but the 5 of them are 1.41". This happened when we went from 10s to 30s exposure with the guider. When we changed the exposure time back. Curious ..... While we wait for r SoS to calculate the S/N, we started a 4th exposure, but when we saw that we finished, we aborted the 4th exposure. We finished this plate in 3 exposures. Cart 5 plate 1452 ------------------ FK5ed again. Every plate is pointing at very different direction from the precious plate. We used spiral pattern to find the fk5 star. It was ra=9" and dec=-20" to find the fk5 star. 06:05Z While setting up, Guider showed that 6 stars had 1.41" FWHM again (magic number 1.41). We stopped Gunn guider and used the old guider and the numbers were different. We switched back to Gunn guider one more time to see the FWHM and 6 stars had 1.41. We decided that it was hard to judge our efficiency etc. with this magical 1.41" FWHM we are getting from gGuide so we went back to the old guider. Maybe some param file gGuide uses got confused??? We think exiting sop and restarting might help, but since we are getting good data, we decided to go on with the old guider. We finished this plate with 3 exposures. Cart 6 Plate 1773 ------------------------- Previous plate's offset or clearing the offset did not find the field. We tried the offsets from cart 4 plate 1748 since they arecloser in position than the previous plate. This helped us find the fk5 (we caught the defraction spike). This plate has signal from last dark run. We finished this plate with two exposures + previous exposures. After the first science exposure, we got another sky residual warning. I am suspecting clouds for these --- or is it something else? sdR-r2-00026121.fit: WARNING: Max sky-residual chi2 = 73.1649 at 8956.27 Ang (ignoring 5577) cart 9 Plate 1462 ------------------------ We tried putting in offset from a plate that had similar position as this one, but it did not work this time. We had to spiralPattern. We finished this plate in three exposures. cart 7 plate 1396 ------------------- gStare on gotoField. we are close in position to the previous plate. The seeing got worse (confirmed by DIMM). It is now around 2.0". We did a postCalib was we w waited for SoS to calculate the S/N. We are approaching twilight (less than 10min to twilight) and there is no time for another cartridge. We finished with 3 exposures. 11:15Z We put cart3 plate 1601 on the telescope and close. endNight did NOT finish successfully. This is due to the permission set for /mcptpm/53112. Pete who ran endNight did not have permission to access this directory which is woned by vxworks. I believe this happened last night and Craig added me to the vxworks group so that endNight runs successully. Some of the observers seems to be in vxwork group, but not all. We changed the permission of the /mcptpm/53112 so that everyone has access to it and reran endNight. Pete filed a PR so that all observers are in vxworks group. After running it the second time, it failed again. So we decided that Atsuko will run endNight and hopefully it will successfully complete. Maybe changing permission to the directory was not good enough. Here are the error messages from the first endNight failure: Error: Found a problem with ioptape.archlog! The tapes may not have written corr ectly! sp1> tb Found a problem with ioptape.archlog!
