Abstract
SN 2023ixf, recently reported in the nearby galaxy M101 at a distance of , was one of the closest and brightest core-collapse supernovae (CCSNe) in the last decade. In this work, we present multi-wavelength photometric observation of SN 2023ixf with the Multi-channel Photometric Survey Telescope (Mephisto) in bands and with the twin 50-cm telescopes in bands. We find that the bolometric luminosity reached the maximum value of at 3.9 days after the explosion and fully settled onto the radioactive tail at days. The effective temperature decreased from at the first observation and approached to a constant of after the first two months. The evolution of the photospheric radius is consistent with a homologous expansion with a velocity of in the…
