OSU/RC Queue Observing UTC 2010 Sep. 30 (civil date Sept.29/30, 2010) =============================================================================== Observer: Jeff Blackburne (OSU), Matthias Dietrich (OSU) Observing Assistant: Steve Allason Support Astronomer : Dave Thompson Instrumentation : Tim Shih =========== Instrument: =========== Lucifer ========= Summary: ========= Photometric night with seeing of 0.7 arcsec at the beginning, 0.5 arscec in the middle and around 0.3 to 0.4 arcsec in the second half and toward the end. Predominantly H,K broad-band photometry and some long-slit spectroscopy - OSU_sn2008s K-band - OSU_atlee H,K-band for MS2053 H,K-band for CL0016 - UM_luci K, OH1190, Pabeta imaging for V2468Cyg 210zJHK in z, J, K for KT Eri, phot.standard at the end is missing, since the sky became too bright and the guide probe was lost - ND_sn09ig J and H-band imaging 0:50 open dome 1:15 sunset skyflats K-band 2sec 1:04 1:05 ca. 18500 cts (10 frames) 1:12 ca. 12000 cts (10 frames) 1:15 ca. 9500 cts (10 frames) 1:16 ca. 8200 cts (10 frames) skyflats H-band 2sec 1:18 ca. 18000 cts ( 2 frames) 1:18 ca. 13000 cts (10 frames) 1:19 ca. 9500 cts (10 frames) 1:20 ca. 7000 cts (10 frames) skyflats J-band 2sec 1:22 ca. 10000 cts 1:23 ca 7500 cts (10 frames) up-date pointing of the telescope ============= OSU SN2008S ===-========= 1:30 slewing to target position 1:35 starting K-band imaging (10s 3times per position) seeing ~0.7 arcsec =========== OSU Atlee =========== 2:00 slewing to target position 2:03 pre-stand.script started before we had to change the relative offset to absolute H- and K-band images taken 10s normal o2dcr 2:06 OSUatlee.ms2053_H.script started (finished 2:53) background around 28000 to 30000 cts (70s might be a little long) seeing ~0.5 arcsec 2:54 OSUatlee.ms2053_K.script started with DIT 50sec Background at ~50000cts ---> too high DIT changed to 10sec NDIT=5 integrated 3:03 OSUatlee.ms2053_K.script re-started (finished 3:30) background at ~12000 cts in an individual image seeing ~0.4 arcsec 3:31 OSUatlee.ms2053_postStand.script started (3:34 finished) ========== UM Luci ========= 3:40 at the target field, starting with the imaging for V2468Cyg guide star out of reach --- turned out to be a typo (26deg instead of 29deg). Acquisition script changed, next waiting for collimation K-band image at around 40000cts in the background and the stars are donuts - but no a focus problem instead the stars are saturated the DIT was changed from 30s 4x integrated to 10s 12x integrated 4:10 K-band imaging for V2468Cgy seeing ~0.4 arcsec (finished 4:50) 4:51 OH1190 imaging test frame with 60s 2x integrated mer mode ---> too bright again ---> DIT = 20s 6x integrated mer 4:53 OH1190 imaging script started (finished 5:27) 5:29 Pa_beta tested with 60s 2x, again background too high and stars saturated ---> DIT=20s 6x integrated mer mode 5:31 Pa_beta imaging script started (finished 6:10) seeing < 0.4 arcsec The spectroscopy part for V2468Cyg has been deferred to the next Lucifer night of this run, since the airmass would have been too large form most of time if the spectra would have been taken ================ ND sn09ig luci ================ 6:10 slewing to the target 6:15 J-band script started and 6:43 finished seeing ~0.5 arcsec and AM(z) = 1.65 6:44 H-band script started Lucifer needed to be initialised (several times) since the filter were hanging Moon rise 6:50 H-band script re-started and finished 7:18 seeing ~0.5 arcsec and AM(z) = 1.4 ============ OSU Atlee =========== CL0016 field to avoid a high background and eventually saturated objects the frame the integration time were re-adjusted DIT = 60s 1 o2dcr normal ---> DIT = 20s 3x o2dcr integrated 7:20 recording the pre-standard field necessary to check the pointing 7:30 pre-standard field started and finished 7:33 7:35 OSUatlee_cl0016_H.script started and finished 8:58 8:59 OSUatlee_cl0016_K.script started and finished 9:51 integration time was set to 10s 3x integrated o2dcr background in a single frame (10sec ) ca. 12000 cts 9:56 slewing to post-standard field 9:59 started post-standard field but DIT=10s too long background too high DIT=3s 3x integrated 10:02 re-started post-standard field ========= UM Luci ========= KT Eri HIP19768tell_prior_acq.script and moving the star into the slit 10:27 HIP18768tell_prior_j (finished 10:36) 10:37 HIP18768tell_prior_z (finished 10:45) 10:45 HIP18768tell_prior_k (finished 10:53) 10:54 starting to move KT Eri into the slit 11:08 z-band spectrum KT Eri (finished 11:25) seeing ~0.35 arcsec 11:25 J-band spectrum KT Eri (finished 11:40) 11:41 K-band spectrum KT Eri (finished 11:55) 11:56 acquisition of post-photom. standard FS12 guide star too bright and no collimation could be achieved searching for a new guide star the field was so crowded and FS12 was quite faint it too some time to identify the star 12:31 script for z-band spectra started (2x 300s) however the sky was already so bright (ca. 30 min before sunrise) that after the first z-band spectrum exposure the guide probe was lost preparing for the end-of-night calibrations 12:40 moving the telescope to zenith for skyflats 12:59 J-band skyflat 2sec ca. 27000 cts, sky too high 13:04 sunrise OH1190 skyflats 13:09 2sec ca. 8000 cts (5 frames) 13:11 2sec ca. 10000 cts (5 frames) 13:14 2sec ca. 12000 cts (5 frames) 13:17 2sec ca. 15000 cts (5 frames) Pa beta skyflats 13:13 2sec ca. 12000 cts (5 frames) 13:15 2sec ca. 14000 cts (5 frames) 13:16 2sec ca. 15000 cts (5 frames) 13:20 closing dome end-of-night spectral calibrations for KT Eri 13:21 ...arc_z.script 13:27 ...arc_j.script 13:32 ...arc_k.script 13:37 ...flat_z.script 13:41 ...flat_j.script 13:47 ...flat_k.script the dark script was copied to the dark-calibration script which was run at the end of the night 14:00 ./DoDarks.txt DIT =10 # any positive value, no blanks # allowed NDIT =1 # any positive value, no blanks NEXPO =20 # as NDIT ROE_MODE =o2dcr # o2dcr|o2scr|msr|mer|lir SAVE_MODE =normal # integrated|cube|normal FILENAME =luci_20100517_Dark_ [START_OBSERVING_SETUP] DARK DARK =o2dcr 20 1 20 DARK =o2dcr 30 1 20 DARK =o2dcr 50 1 15 DARK =o2dcr 70 1 15 FLUSH_DETECTOR FLUSH_DETECTOR DIT =3 # any positive value, no blanks # allowed NDIT =3 # any positive value, no blanks NEXPO =25 # as NDIT ROE_MODE =o2dcr # o2dcr|o2scr|msr|mer|lir SAVE_MODE =integrated # integrated|cube|normal FILENAME =luci_20100517_Dark_ [START_OBSERVING_SETUP] DARK DARK =o2dcr 10 5 20 DARK =o2dcr 30 4 15 DARK =o2dcr 10 12 15 DARK =mer 60 2 15 DARK =mer 20 6 15 DARK =o2dcr 20 3 20 DARK =o2dcr 10 3 20 DARK =o2dcr 30 2 20 DARK =mer 120 1 15 DARK =mer 300 1 10 FLUSH_DETECTOR FLUSH_DETECTOR unfortunately, the filenames have to be changed but this shouldn't be too difficult, I guess. luci_20100517_Dark_ to luci.20100930.dark.
