Moon down during all night
Humidity 40%, wind below 5m/s all night, some low clouds in the horizon non-photometric
Seeing 0.5" at the beginning of the night, subsequently around 1".
23.45 Start of twilight
00:03 L745a - spectrophotometric standard
8x100s V-band. Seeing < 1", but images have between 1.1" and 1.4" because of airmass ~2.5
01:11 Image Analysis
Seeing around 0.8"
300s Gr#13 classification - Blue continuum. Narrow p-cygni Balmer lines consistent with redshift z=0.024. Approximate expansion velocity: -3114km/s.
1500s Gr#13 classification - Looks like SN II at maximum, z=0.08. Approximate expansion velocity: -12904km/s
600s Gr#13 classification - SN Ia, -5d, z=0.05
04:42 L745a - spectrophotometric standard
12x200s in r and 12x200s in i. Seeing 0.8" - 1.2"
4x300s in g. Seeing 0.8" - 1.0"
900s Gr#13 classification - SN Ia at z=0.06, around max
600s Gr#13 classification - SN Ia at z=0.05, around max
900s Gr#13 classification - Not clear. Emission at 8400A. Seems to be p-cygni, but is not sure. In case of H alfa, the object would be at z=0.28.
Taken 2 aquisition images with 20 and 40s. The target was not visible, so we gave up.
08:56 EG274 - spectrophotometric standard
600s Gr#13 classification- SN Ia z=0.05 around max
600s Gr#13 classification - SNID matches with SN Ib at z=0.04 or SN IIb post max at z=0.02.
