Observing: Morgan Fraser, Tom Reynolds Support Team: Seppo Mattila TAT: Lluís Galbany, Stefan Taubenberger Weather conditions Start of night: Thin cirrocumulus covering most of sky, seeing ~1" Middle of night: Closed due to clouds End of night: Clear, seeing 1-1.5 ------------------------------------------------ Calibrations Evening: EFOSC biases, spec flats Software error caused 5.0" slit to be used instead of 1" throughout, so only 1.5" data is good Clouds and this problem prevented evening skyflats ------------------------------------------------ Start of night: Had to restart observing system multiple times and wait for TOś to try and solve 1" slit problem. No time for evening std, twilight taken up by attempt to fix system. COULD NOT SOLVE PROBLEM: all spectra taken with 1.5" slit, 1.0" slit unavailable 23:00 SN2016ase (follow-up): Could not acquire even with deeper acquisition image due to clouds 23:15 Image analysis 23:30 Standard, EG274, 1.5" slit only 23:33 End of twilight 23:40 SN2016AJ (follow-up): Could not see target in a long R acquisition image, so did not continue. Assume we need cloudless night 23:47 ASASSN15oz (follow-up): 3x200s R, can see the target. 00:02 Gaia16awz (Classification): 300s, Gr13, 1.5" slit. Not enough signal, took 1200s same setup. Still could not extract spectrum 00:35 Gaia16awy (Classification): 1200, Gr13, 1.5" slit. CV, spectrum observed through clouds 01:02 Gaia16awm (Classification): 1200 Gr13, 1.5" slit, CV 01:32 AT2016ekg (Classification): 300s Gr13, 1.5" slit, cut short by closure. Early Ia, few days pre-max. 01:43 CLOSED DUE TO CLOUDS 04:05 REOPENED 04:05 SN2009ip (follow-up): Could not see the galaxy clearly in acquisition, aborted due to cloud 04:14 OGLE-131 (follow-up): Again aborted due to cloud 04:18 PS16dnm (classification): Could not acquire, even in a deep 60s exposure. Didn't look like clouds, target seems faint Clouds almost all dispersed 04:24 PS16dnp (classification): 600s, Gr13, 1.5" slit. Early Ia, few days pre-max. 04:42 PS16dno (classification): Could not see target in acquisition image, presumably faded. 04:48 SN2009ip (follow-up): Observed 10x150 B, 8x150 V 05:48 OGLE-131 (follow-up): Observed 9x200 B 06:28 SN2016AJM (follow-up): Observed 4x300 B 06:54 ASASSN15og (follow-up): Observed BVgri, Gr16 2700s 1.5" x 2. Did not get spectroscopic flats, multiple problems with saturation and arc lamps being on 10:00 OGLE15xl (follow-up): Observed z 200sx9 10:00 Beginning of twilight |
