00:47 SN2016gkg                  01:34:14.46   -29:26:25.0   60+16   1  UBVRi + gr11+gr16      FOLLOW-UP. SN detected in all the bands, and good spectra.
02:06 OGLE17aaj                   01:56:24.92   -71:04:15.7   52          1  gr11                             FOLLOW-UP. Spectrum with lower S/N as compared to the previous one taken in the first subrun, He II detected.
02:57 SN2016ija + SN2016ae 04:12:07.62   -32:51:10.9   53          1  gr16                             FOLLOW-UP. We put the slit on both SN2016ija and SN2016iae, good spectra.
04:03  We attempted to classify AT2017jt, the possible SN was not detected in the acquisition image, we skipped it. 
04:08 OGLE-2015-SN-043     05:29:42.71   -72:26:23.7   60+51    UBVRi                               FOLLOW-UP.

06:13 AT2016jbu                    07:36:25.96   -69:32:55.2   30         1  gr11+gr16                   FOLLOW-UP. Very bright, nice spectra.
06:46 AT2017nw                    11:16:12.61   +02:48:29.1   27         1  gr13                            CLASSIFICATION. SN Ia at z=0.08 around peak.
07:16 AT2017hm                    11:33:10.57   -10:13:18.4   50         1  gr11+gr16                   FOLLOW-UP. Strong signal in both spectra.
08:12 SN2017hn                     13:07:39.46   +06:20:14.6   50         1  gr11+gr16                   FOLLOW-UP. Strong signal in both spectra.
