Since the previous post, SN 2024abfo‘s brightness increased steadily until peak brightness was reached during the night 06 Dec 2024, at 13.81 mag, more than fifteenfold since discovery by ATLAS on 15 Nov 2024 with 16.79 mag. Meanwhile, brightness is back at 16.26 mag on 16 Mar 2025.
Due to using an L filter (Baader UV/IR cut) and not a V band filter, the measurements here overestimate the brightness by approx. 0.2 mag.
