Observing: Morgan Fraser, Tom Reynolds Support Team: Cosimo Inserra TAT: Cosimo Inserra, Kate Maguire Weather conditions Start of night: Some thin cloud, seeing ~2" Middle of night: Seeing varying between 2" and 3" End of night: Seeing still ~2", wind rising to ~12 m/s with pointing restrictions at end of night (hence no standard could be observed at the end of the night).------------------------------------------------ Calibrations Evening: SOFI ------------------------------------------------ 22:54 EG274 - no light getting to EFOSC, TO went to telescope to investigate. Problem fixed. 23:21 EG273 - 1" slit standards 23:30 End of twilight 23:32 AT2016bln (follow-up) - Gr#13 1.5" slit 2700s. Good S/N. 00:25 SN2016aiy (follow-up) 2x2700s Gr#16 1.5" slit 02:24 Gaia16avq (classification) 900s Gr#13 1.5" slit (seeing currently ~3") Normal Ia at ~maximum light, z=0.07 02:49 AT2016dgj (classification) 1200s Gr#13 1.5" slit (seeing ~3") 91T-like SN Ia at +2-3 weeks, z=0.06 03:14 Gaia16avx (classification) 1800s Gr#13 1.5" slit (seeing ~2.5") Blue and featureless, with possible absorption at MgII - returning later! 03:54 AT2016dln (classification) 900s Gr#13 1.5" slit (seeing ~2.5") Blue continuum, galaxy lines, and a broad feature around Halpha. SN II. 04:22 Gaia16avx (follow-up) 2700s Gr#11 1.5" slit Spectrum is of an early type galaxy. Suspect that target was not in slit, and we are getting flux from the close galaxy to the N. Looking again at the first spectrum, the separation between the components is more like 10 Ang. So perhaps this is not Mg II... 05:22 Gaia16avy (classification) Gr#13 1.5" slit SN Ia, ~maximum light, z=0.07 05:44 AT2016egz (classification) Gr#13 1.5" slit Blue spectrum with weak narrow Halpha and O 5007. Looks like a very young SN, will revisit with Gr#11. 05:55 AT2016dkf (classification) Gr#13, 1.5" slit 91T-like SN Ia, -3d, z=0.05 06:10 AT2016egz (follow-up) 1200s Gr#11, 1.0" slit. Very nice spectrum, narrow features in blue, emission lines unresolved. 06:38 LSQ15adm (follow-up) Could not acquire target due to poor seeing 06:46 OGLE16bqu (classification) Not visible on acquisition image 06:52 OGLE16bqx (classification) - Gr#13, 1.5" slit. SN Ia at max at z=0.11 07:13 Gaia16avu (classification) Blue contiuum, CV or similar. Nearby galaxy unrelated. 07:24 Gaia16avh (classification) SN Ia, +2 weeks, z=0.05 07:40 ASASSN-15lh (followup) 2x2700s Gr#11, 1.0" slit (seeing has now improved to ~1.3") 09:44 SN2016aqf (follow-up) 1800s Gr#13, 1.5" slit (seeing back to ~2.5", wind above 12 m/s so pointing restrictions). 10:08 Start of twilight 10:21 AT2016eig (classification) Young Type II SN at z 0.03 10:41 AT2016eif (classification) SN Ia, z=0.07, around max (Note that no standard was taken at the end of the night due to pointing restrictions) |
