Daichi Hiramatsu, Iair Arcavi, Jamison Burke, Griffin Hosseinzadeh, D. Andrew Howell, Curtis McCully, Stefano Valenti report/s a classification of object: SN 2018bvi

Type: SN Ib
Redshift: 0.02417

Remarks: Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and GELATO (Harutyunyan et al., 2008, A&A, 488, 383), we find several good fits to Type Ib around the maximum light at the redshift of proposed host galaxy (z=0.024170; SDSS DR6, via NED). There are some disagreements in the phase, however, the last non-detection limit suggests it is around maximum.
