00:51 SN2016ije 01:58:30.32 +12:55:27.9 1 gr13 + BVRi 50+20 FOLLOW-UP. Good spectrum for this 91bg-like.

02:02 SN2016iae 04:12:05.53 -32:51:44.7 1 gr13 40 FOLLOW-UP. We placed the slit on both SN2016iae and SN 2016ija, as they occur in the same galaxy. SN2016ija's trace is on pixel 727 in this case. SN2016iae is the bright trace in the center of the 2d spectrum. Both nice spectra.

02:49 SN2016ija 04:12:07.62 -32:51:10.9 1 gr16 50 FOLLOW-UP. Again, we placed the slit on both SN2016iae and SN 2016ija, as they occur in the same galaxy. SN2016iae's trace is on pixel 370 in this case. SN2016ija is the trace in the center of the 2d spectrum. Both nice spectra.

03:41 gd71 05:52:27.51 +15:53:16.6 1/1.5 gr11+gr16+gr13 25 Spectral standard.

04:06 AT2016hmq 04:25:04.91 -07:33:56.2 1 gr13 40 FOLLOW-UP. Type II, good spectrum.

04:44 AT2017jy 04:32:44.43 -05:53:30.4 1 gr13 27 CLASSIFICATION. Normal SN Ia at +8d since max, at known z=0.04.

05:10 OGLE16dmu 04:48:26.34 -62:20:10.6 1 gr13 52x2 FOLLOWUP. Two exposures, decent spectrum of this faint target.

06:55 RU_152 07:29:56.00 -02:05:39.0 1 BVRi 6 Photometric standard.

07:01 L745a 07:40:19.60 -17:24:42.0 1 gr11+gr16+gr13 15 Spectral standard.

07:15 AT2016jbu 07:36:25.96 -69:32:55.2 1 gr11+gr16 40 FOLLOW-UP. good spectra, still very bright.

08:00 AT2017jr 08:33:49.81 -25:02:24.5 1 gr13 22 CLASSIFICATION. Normal SN Ia around peak, z=0.063 (redshift from galaxy line).

08:22 ATLAS17agh 11:10:27.18 +28:41:42.4 1 gr13 22 CLASSIFICATION. Normal SN Ia after peak at known z=0.03.

08:44 PG1047 10:50:05.65 -00:01:11.3 1 BVRi 4 Photometric standard.

08:48 LTT3864 10:32:13.90 -35:37:42.4 1 gr11+gr16+gr13 15 Spectral standard.
