Lina Tomasella, S. Benetti, E. Cappellaro, M. Turatto, I. Salmaso report/s a classification of object: SN 2019lrb

Type: SN Ic
Redshift: 0.027439

Remarks: Spectrum similar to those of type Ic supernova SN 1990aa around maximum. However, the spectrum is also consistent with those of SNe Ia at maximum. The spectral continuum is very red allowing for a high host galaxy reddening which is also confirmed by an intense (EW~0.23nm) NaID absorption. The redshift has been derived from the narrow host galaxy lines. The expansion velocity deduced from the Si II 635.5 nm is about 10500 km/s
