OSU/RC Queue Observing: UTC 2010 Mar 16 =========================================== ========== 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 sky flats. (2) Time Lost: - ~1 hr 40 min to inital condensation on the dewar window - Additional time lost to the condensation ============== Detailed Notes: ============== UTC 1:08-- Test Flat exposures of 2 sec and got ~18,000 counts. * On Flat 13; seems to be good exposure. UTC 1:12 -- Started H2 Flats UTC 1:17 -- Things became messed up until Flat 21 UTC 01:30 -- H2 & Bracket Gamma Sky Flats Continue UTC 01:38 -- last narrow band flat is Flat_0120 UTC 01:39 -- test K_s; run 30x; K_s flats will have luci_20091217_Flat_???? UTC 01:45 -- sun is setting; 12k cts 5s 12.05 sky brightness H band #0122 UTC 01:55 -- sun has set; End H band #0152; UTC 02:00 -- Position of camera may be wrong; may not have properly moved to end point based on black boarder seen on top and right edges of flats. UTC 02:06 -- 10s test H Flat after moving camera to correct position; exp still with boarders, even moving again from 1.8 to 3.75 back and forth, problem persists. UTC 02:13 -- Tried initialize Lucifer, problem remains annoying. UTC 02:25 -- Looking through 2010/03/15 flats we find similar boarders and dark sections present in same location. UTC 02:30 -- Pointing to Target Star: BS9118 06:22:43.84 -00:36:29.0; took image UTC 02:46 -- measured position of Target star, used pointcoor to calculate offsets; Entered IE values and corrected the pointing; Need 2nd pointing star @ low elevation UTC 02:53 -- 2nd pointing star: BS9133 08:27:12 -25:07:58; calculated pointcoor; UTC 03:05 -- Redoing 1st pointing due to bad elevation, moving to BS9122 07:00:51 +48:29:23.1; calculated new IE values and corrected pointing New IE: -23.6 Ca: 5.2 UTC 03:15 -- Took exposure to check the position. Redoing 2nd pointing BS9133 to check IE UTC 03:33 -- Went to 1st target of the night, OSU Martinilens/MaritiniLensHK; taking test image there is a really large asymmetric dark blob at the bottom of the image; thought to be condensation, focus also very bad; corrected focus; CALLING MUNICH...Blob seems to be on window, not on filter, not just at one spot; slewed back to zenith to visually investigate the blob blocking ~ 25% of image. (UTC 3:59) UTC 04:08 -- Giant brain shaped blob is actually condensation on the dewar window. The LBTO staff will try to remove it. Humidity is rising and the SA is concerned. UTC 04:47 -- Condensation manually cleared. Humidity is still high. UTC 04:52 -- Humidity is high. Watching it for a bit before making a decision to stay open or closed. UTC 05:10 -- Re-opening the dome since humidity is in the yellow range. =========== OSU_martini =========== UTC 05:18 -- Doing OSU_martini HK Acquisition UTC 05:41 -- Condensation is reforming and humidity is rising again UTC 06:11 -- Condenation is very large and we are unable to see the target. Called Walter to see if it is okay to be observing with this much frost. UTC 06:28 -- Abandon the martini object because of the frost difficulty. =========== um_PTF10bjs =========== UTC 06:28 -- move to um_PTF10bjs; the guide star was not picked within the FOV of the guider and a new guide star was chosen that maintained the 90 slit PA. the new guide star will let us reposition the slit if we need to. we will have to readjust the offsets as needed ... humidity is dropping and the condensation is diffusing. humidity threshold seems to be ~80% UTC 06:59 -- centered the SN and starting K band science script UTC 07:03 -- the telescope commands were not commented out in the science script! we lost the target and will now need to reacquire the target.

UTC 07:43 -- running science script for K spectrum again, however with smaller relative offsets for Supernovae. -----After this point our emacs file became corrupt and so we are manually reconstructing the log---- --running science script for the supernovae for J band spectrum. Spectrum was very weak, and checked whether target was in slit. Seeing was 1.5-2.2 so we changed to a 1" wide slit and reexecuted the J band script. Visible, weak spectrum. -- Observed hd109615 Telluric (for the supernovae) star on the 1" slit. =========== OSU_sag =========== In H band: -- OSU sag2mass1 script, executed twice with decent results. -- Velocity standard HD90861- then Telluric standard for object HR4875 -- OSU sag2mass2 script, problems finding the guide star and focus and seeing were bad. Tried unsuccessfully 3 different guide stars. -- OSU sdss215, took several spectra with poor signal-to-noise -- Twilight started; we still had the large blob of condensation which hinder us from taking sky flats, so we closed the dome and took spectrascopic flats and arcs for observations. -- At the end of the night the instruement manager for LUCIFER lost communication with the MOS server, but were able to contact others to reconnect.
