Investigation of the Type Ic-BL Supernova SN 2020adow

We present UBVRI photometry for the type Ic-BL supernova SN 2020adow over the period from $$-6$$ to 98 days relative to maximum light and 11 spectra in the interval from $$-7$$ to 47 days. We have determined the following basic parameters of its light curves: the dates and magnitudes at maximum light, the decline rates at two stages of evolution, and the peak absolute magnitude MV=-18m.0 . The light curves of SN 2020adow in absolute V magnitudes and the color curves are compared with the corresponding curves for type Ic and Ic-BL supernovae. We have modeled the spectra with the SYN++ code, identified the main absorption lines, and determined the ejecta expansion velocities.
