01:08  SN2016ezh   1           gr11+gr16                40    FOLLOW-UP.  Blue spectrum, with strong emission features, similar to the one taken on Dec 22.
01:56  OGLE17abx   1           gr13                         52     FOLLOW-UP. Type II with long rise, good spectrum.
02:47  SN2016aqf   1            gr13                         52     FOLLOW-UP. Nebular Type II spectrum, good quality.
03:41  SN2016iyd    1            gr11                         40     FOLLOW-UP. Type II spectrum, broad features, good quality.
04:16  AT2016jbu   1            gr11+gr16               40     FOLLOW-UP. High S/N, blue spectrum with Balmer and He emission lines, also narrow P-Cygni.

05:56 image analysis
06:06  AT2017hm  1             gr13                         17    CLASSIFICATION. Normal SN Ia before or around peak at z=0.02-0.03.
attempted to acquire SN2016B, too close to the moon.
06:27  SN2017hn   1            gr11+gr16                60    FOLLOW-UP. Type Ia, good spectrum.
07:31  ATLAS17abx 1           gr13                          27    CLASSIFICATION. Normal SN Ia about a week after peak at z=0.06.
07:59  ATLAS17adf 1           gr13                          27    CLASSIFICATION. Looks like the galaxy spectrum taken by SDSS, z=0.011.
08:24  LTT3864     1            gr11+gr16+gr13      15    Spectral standard.
08:38  AT2017hl   1             gr13                          22   CLASSIFICATION. Type Ib  in the center of the galaxy (z=0.023).
