OxQUB

Several matches with normal SNe Ia one week before maximum light were obtained using SNID (e.g., SN1996bl at t = -4d). Redshift from the known host (on NED). The spectrum is considerably reddened for a normal SN Ia near peak, and the transient is intrinsically faint with M_c = -17.4 in ATLAS. This is possibly due to significant host extinction, as suggested by the presence of the NaI doublet (5890A/5896A) at the host redshift.
