OSU/RC Queue Observing: UTC 2010 Mar 17 =========================================== ========== Observers: ========== Peter Garnavich (ND), Matthias Dietrich (OSU), Rachael Beaton (UVa), Katherine Rueff (ND) Observing Assistent: Wayne Wack Support Astronomer: Olga Kuhn Instrumentation: Doug Officer ========== Instrument: ========== LUCIFER ============= Quick Summary ============= (1) Calib: Some evening sky flats, morning sky flats, darks (2) OSU_Martini: Did the J band script. Seeing was 1.5" (3) OSU_Sag: 2mass2 + Telluric (4) OSU_HeI_sdss1028: completed observation (5) ND_sn08dc: did j band only; (6) OSU_SN2008S: completed program Time Lost: - 4.25 hours: 3.5 to telescope and 0.75 to lucifer; main trouble were inaccuracies in the pointing useful tool to check guide stars and to look for alternative ones DS9 Guide Field Script Tool: OSURC@obs3 ~/obs_mar2010$ ls OSURC@obs3 ~/obs_mar2010$ cd OSU_SMBH "Choose program to do" OSURC@obs3 ~/obs_mar2010/OSU_SMBH$ ls "see what's in program file" OSURC@obs3 ~/obs_mar2010/OSU_SMBH$ more OSUdietrichSMBH.SDSS0942_acq.script "Find target wanting to aquire, pulls info; find Rot Ang" OSURC@obs3 ~/localprog$ perl lucifer2.pl 09:42:09.0 52:07:14.0 09:41:46.0 52:10:10.0 0.0 sdss0942 > sdss0942.sh "Ra target/Dec" "Ra Guide/Dec" "Rot Ang" namefile > makefile "Should open in new frame in Ds9; magenta are target and guide; green are highest mag; need guide star within large red ring/ out of problem areas indicated" "Will make a png file as well" ============== Detailed Notes: ============== UTC 01:05 -- Test narrowband BR_gamma & H2 flat; cirrus clouds seem to cause enhanced brightness UTC 01:22 -- running flatbrg.txt and flath2.txt script to take sky flats. Narrow band flats stopped due to too much cloud brightness. UTS 01:30 -- Data from LUCIFER is not being saved to the proper path to OBS repository, although they are saved on LUCIFER computer. Brute force copying data from LUCIFER to OBS for data log. UTC 02:00 -- doing H band flats with cirrus clouds present. When trying to change the filter to J, LUCIFER gave errors, causing us to have to recover the system. UTC 02:10 -- Recovered LUCIFER and started pointing; picked pointing star: Pearson BS9126: 7:30:35 +29:51:12 UTC 02:30 -- Unable to slew to pointing star due to problem with OSS with telescope UTC 03:00 -- telescope is back - starting to do the pointing BS9126, calculating the new IE and CA values: IE: -8.2 CA: -15 UTC 03:13 -- going to low elevation pointing star BS9123: 6 59 45 -30 13 50 corrected IA 265.91 (required 9.4 arc sec correction). Slewing back to 1st pointing star @ high elevation. =========== OSU_martini =========== UTC 03:25 -- Checked object is visible; it is. UTC 03:47 -- Went to 1st telluric, checked spectrum with Ds9, everything looks good. UTC 03:54 -- traveling to 1st target.Seeing = 1.0 arcsec acquisition started but when small offset is executed the guide probe failed and get stalled. Homing the guide probe UTC 04:06 -- tried acquisition again and again the same error in the guide probe, possibly communication problem UTC 04:30 -- we seletced an alternative guide probe at 09 00 19.50 +22 35 09.2 which isn't located too close to the vignetting area. Now we got a readout error of the CCD. error 90 - WOW UTC 04:40 -- attempted aquisition again once system was recovered; object was properly moved into to the slit, taking 3x30 sec integrated exposure to check, seeing 0.9 arcsec, humidity at ~40% UTC 04:58 -- starting observing script for J-band spectrum, seeing around 0.8 to 1.0 arcsec (approx 2hrs)- The seeing appears to be highly variable up to nearly 4 arcsec there are spectra of both blobs visible in the diff spectra of two 10min exposures Seeing has been getting steadily worse for about an hour; currently at 2.5 arcsec. seeing variations don't help to get good spectra. inthe following 4 spectra, the signal is lower, UTC 06:36 -- humidity down to ~6% UTC 07:03 -- Finished exposures, executing spectroscopic lamp flat at target's position. UTC 07:08 -- Headed to 2nd Telluric star to take spectrum. UTC 07:17 -- Exposure taken of 2nd Telluric; 15x2sec integrated. =========== OSU_Sag =========== UTC 07:23 -- Aquiring target OSU sag2mass2, seeing at 0.8-2 arcsecs, slightly varying. UTC 07:34 -- Started H band spectra for 2mass2 (saved files as luci_20100317_marini_0042-0050.fits) then changed the file names to luci_20100317_2mass2_0001-0004.fits UTC 07:45 -- Slew to Telluric standard star HR5037 UTC 07:52 -- telescope guide probe problems, UTC 08:51 -- telescope is finally back and working after guide problems sufficently fixed. UTC 08:52 -- Slew to Telluric standard star HR5037 again to test the pointing; pointing seems still to be off (surprise?) UTC 09:16 -- Doing a low azimuth pointing star, the pointing is showing to be significantly off at the moment. UTC 09:22 -- Heading to high elevation pointing star instead to attempt to get pointing on. It was corrected UTC 09:26 -- Headed to 2nd Telluric standard. the pointing still needs some tweeking UTC 09:40 -- guide probe found, next object into the slit seeing 1.5 to 2.5 arcsec variable UTC 09:49 -- completed! ================ OSU_HeI_sdss1028 ================ UTC 09:55 -- move to the HeI sdss1028; observations are in the parallactic angle; bad guide star coordinates fixing and trying to find the guide star UTC 09:58 -- new guide star works; setting PA=0; adjusting the slit to match the seeing (0.75") UTC 10:11 -- start script! OSU_HeI_sdss1028 . UTC 10:25 -- beautiful S/N! UTC 10:29 -- start telluric hip52027; can't find guide star; checked coords; will try to adjust field by hand UTC 10:36 -- adjusted pointing on the telluric star; UTC 10:41 -- starting obs.script for HIP52027 ========= ND_SN09dc ========= UTC 10:50 -- moving to ND_SN09dc, lost a few minutes for a typo in the script UTC 10:55 -- now really moving to ND_SN09dc; poor pointing; moving to nearby pointing star UTC 11:01 -- lucifer started taking data before the telescope was fully collimated. this has been a problem both tonight and last night. stopped script (first ~2 images are not so good) UTC 11:09 -- checked pointing with the bad images; looks good, restarting the J band script. seeing ~0.8" but still variable UTC 11:37 -- seeing is improving; will only do the J band =========== OSU_SN2008S =========== UTC 11:47 -- moved to SN2008S started H script; pointing great!; seeing is poor (high airmass) 1.3" but variable UTC 11:52 -- seeing is 1.3" in H from the first exposures; quick reduction looks good, though we can't see the SN UTC 12:13 -- seeing is better 0.9" UTC 12:22 -- start K script; starting to get bright, will go as long as we can UTC 12:30 -- on-sky seeing 0.9" and improving into twilight UTC 12:40 -- fine! ==== CALS ==== UTC 12:45 -- JH low light flats UTC 01:04 -- Finished low light flats; start bright flats UTC 01:16 -- Some clouds on the west horizon. Finished Flats. Flats, Arcs etc ... for the night's observing - OSU_Sag: Arc & Flat - OSU_HeI: Arc & Flat Posted data log will include these, but not the darks. Darks will be acquired for all programs during the day but will not be in the data log.
