C. Ricci (PUC), J. L. Prieto (UDP/MAS) report/s a classification of object: SN 2016ggb

Type: SN Ia

Remarks: An optical spectrum (range 3600-9000 Angstroms) of ASASSN-16km/AT2016ggb was obtained on UT 2016-09-13.3 with the B&C spectrograph mounted on the du Pont 2.5m telescope at Las Campanas Observatory. The spectrum is consistent with a Type Ia around peak heavily contaminated by the host galaxy light. After correcting for the redshift of the host galaxy, we measure a Si II 6355 expansion velocity of ~12000 km/s.

The following Classification spectrum was provided:
