Observing: Morgan Fraser, Tom Reynolds

Support Team: Seppo Mattila

TAT: Lluís Galbany, Stefan Taubenberger

Weather conditions

Start of night: Some thin cloud, seeing ~1"

Middle of night: Thin clouds at horizon, seeing ~1"

End of night: Clouds caused closure, but reopened. Seeing ~1"



Evening: EFOSC biases, spec flats


Start of night: Had to restart TCS, prevented us from taking skyflats

22:55    Image analysis

23:13    SN2016ase (follow-up): Gr13, slit 1.0", 2700

23:33    End of twilight
00:06    AT2016eiy (follow-up): Gr11+Gr16, slit 1.0", 900s each. Mis-acquired initially, took spectrum of nearby bright source, lost ~40 mins
01:35    SN2016adj (follow-up): Attempted to acquire for spectrum, could not reliably find object. Took 3x100s i-band imaging to determine if object still present
01:57    Standard, LTT7379
02:16    LSQ15adm (follow-up): Bgi 9x200s, Vr 6x200s. Small software fault cost 5-10 minutes
05:06    Attempted image analysis as there was evidence of PSF distortion in final LSQ15adm images. Actuator problem caused downtime for ~40 minutes
05:48    OGLE15sd (follow-up): 12x200s r
06:40    ASASSN16hw (classification): SN Ia, pre max, approx -5 days
06:49    AT2016egz (follow-up): Gr13, slit 1.0", 1200s (also refocused)
07:20    OGLE15qz (follow-up): 9x200s g
08:00    PSNJ2150 (follow-up): took spectrum of what we thought was target, was nearby source. Target was very faint, not detected in acquisition image
09:55    REOPENED
10:00    SN2009ip (follow-up): 2x100s r, 10x150s i
10:06    Start of twilight
10:45    Standard, VMA2, only 1" slit
            Quite cloudy, unable to take skyflats
