McCullyGlobal SN ProjectSN Ia-91bg-like0.009867Global SN ProjectUsing the Supernova Identification code (SNID, Blondin and Tonry 2007, Ap.J., 666, 1024), we find a good fit to both normal and 91bg-like SNe Ia one week before maximum. Given the redshift of its host (z=0.009867, NGC4696 via NED), SN2017ejb appears faint (R = -15.9) for normal SNe Ia. Given the low luminosity of SN2017ejb and its remote location, further observations are encouraged.
