Daytime calibrations: PESSTO_bias PESSTO_calib (without arcs, and not complete dome flats - we will run it at the end of the night) Observers: Ken Smith, Aleksandar Cikota TAT on duty: Michel Dennefeld, Morgan Fraser, Mark Magee Support team: QUB, TBD, Mark Magee Weather conditions: clear, windstill, humidity 48%, seeing (DIMM) ~0.9" 00:40 UT: follow up of AT2016iks, gr11+gr16+flat (we started before twilight ended) 02:03 UT: Standard star vma2 02:35 UT: refocusing 02:40 UT: Follow up of AT2016hmq (2x1800s), seeing ~1", humidity 50%, windstill 03:52 UT: Follow up of SN2016ipf (g11+g16), seeing still ~1", humidity 55%, wind 2.2m/s 04:58 UT: Standard star L745a; seeing 1.04, thin clouds, 56% humidity 05:27 UT: refocusing 05:33 UT: Follow up of SN2016iae; seeing ~1.01, humidity 56%, pyrgeometer -105.7 06:10 UT: Classification of AT2016ile. Seeing is jumping from 1.2-2.2", but it's again clear, and humidity dropped to 47%. (looks like Ia or Ia-91T at 15-30 days past maximum, at z~0.065) 06:55 UT: Classification of AT2016ind. seeing 2.37", and changing rapidly. We did slit 1.5" and increased exp time to 1800s (looks like AGN). 07:35 UT: Classification of AT2016ivt. seeing improved to 1.33". Thin clouds. We did slit 1.0" and increased exp time to 600s (looks like Ia pre-max at z~0.030). 07:55 UT: Classification of AT2016iwk. seeing ~1.0". Thin clouds. (looks like Ia a week after max. z~0.053) 08:12 UT: End of night 08:25 UT: Calibration: PESSTO_calib |
