Abstract (from CDS):

We present our analysis of the Type II supernova DLT16am (SN 2016ija). The object was discovered during the ongoing D 40 Mpc (DLT40) one-day cadence supernova search at r∼20.1 mag in the "edge-on" nearby (D=20.0±4.0 Mpc) galaxy NGC 1532. The subsequent prompt and high-cadenced spectroscopic and photometric follow-up revealed a highly extinguished transient, with E(B-V)=1.95±0.15 mag, consistent with a standard extinction law with RV = 3.1 and a bright (MV=-18.48±0.77 mag) absolute peak magnitude. A comparison of the photometric features with those of large samples of SNe II reveals a fast rise for the derived luminosity and a relatively short plateau phase, with a slope of S50V=0.84±0.04 mag/50 days, consistent with the photometric properties typical of those of fast-declining SNe II. Despite the large uncertainties on the distance and the extinction in the direction of DLT16am, the measured photospheric expansion velocity and the derived absolute V-band magnitude at ∼50 days after the explosion match the existing luminosity-velocity relation for SNe II.
