Optical observations of the Type Ic-BL counterpart to EP 260321a, SN 2026gzf. Left: our optical and near-IR light curve of SN 2026gzf. Right: sequence of GMOS, SOAR, and NGPS spectra of SN 2026gzf. We mask the regions of the emission lines of Hα, Hβ, and [O II] for visibility. Spectra are not corrected for Galactic extinction, which is weak along the line of sight (E(B − V) = 0.02; E. F. Schlafly & D. P. Finkbeiner 2011).
