We report the spectroscopic classification of SN 2018bbl. The target was supplied by the Backyard Observatory Supernova Search (BOSS; http://bosssupernova.com/ ). The observations were performed on 2018-04-26 UT at the 4.1m SOAR Telescope equipped with the Goodman High Throughput Spectrograph using the 400 lines/mm grating, 2 × 2 binning and a slit width of 1.0 arc second, resulting in a spectral coverage from 510-900 nm.
Survey Name | IAU Name | RA (J2000) | Dec (J2000) | Disc. Date | Source | Disc Mag | z | Type | Phase | Notes
| SN 2018bbl | 22 56 54.6 | -37 20 20.9 | 2018-04-24 | BOSS | 17.4 | 0.005979 | II | 2-3 months after peak | (1)
(1) The spectrum shows low expansion velocities (~ 1000 km/s) similar to the low luminosity SN 1997D (Benetti et al. 2001). The phase is based on spectral comparison to similar objects.
