he redshift is obtained by SNID and is consistent with the Coma Cluster. Adopting a standard cosmology with H0 = 70 km/s/Mpc, we obtain a distance modulus of 34.7 mag. This gives a current absolute magnitude of about -16.34. SN2019be is located ~8" away from SN2008dx, which was another type Ia 1991bg-like.
