Absolute magnitude light curves of SN 2018ec after correcting for host extinction (A_V = 2.1 mag). The light curves of the Type Ic SN 2007gr are shown with solid lines, and are shifted vertically by −0.58 mag (optical light curves extrapolated with linear fits for comparison are indicated with dotted curves). The estimated errors for most light curve points are smaller than the symbol size. The epoch 0 is the B-band maximum estimated for SN 2007gr by Hunter et al. (2009).
