Supernova SN 2024abfo Update

Lightcurve of SN 2024abfo from 17 Nov to 01 Jan 2025
Lightcurve of SN 2024abfo from 17 Nov to 01 Jan 2025

Since the previous post, SN 2024abfo‘s brightness has been increasing steadily, peak L/V brightness was 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, back at 15.12 mag on 01 Jan 2025.

Supernova SN 2024abfo in Galaxy NGC 1493 – Dec 2024 – LHaRGB v2

The full frame around NGC 1493 with supernova SN 2024abfo, see marker, and a plethora of smaller galaxies, see the annotated version below.

This image combines RGB data from Nov, more than 12h Ha Data from Nov/Dec and L data from 01 Dec until 09 Dec 2024. Maximum brightness of the supernova was on 06 Dec 2024 at 13.81 mag (L), so this image portraits the supernova around maximum. There was actually not much signal in the Ha data, so the contribution is rather small.

Supernova SN 2024abfo in Galaxy NGC 1493 – 18 Nov 2024 – LRGB v1

Recently, a new type II supernova SN 2024abfo was discovered in the galaxy NGC 1493, on 2024-11-15 by ATLAS, discovery mag 16.793.

This image is processed data from 2024-11-18, I managed to image NGC 1493 and SN 2024abfo on 2024-11-17 and 2024-11-18 so far. Measurements of L brightness in Tycho yields:

2024-11-17: 16.82 – 16.91 mag (median, 2 batches, not reliable, passing clouds)
2024-11-18: 16.70 – 16.64 mag (median, 5 batches)

NGC 1097 and Supernova 2023rve – Galaxy in Fornax – IAS Hakos, Namibia – 18 Sep 2023 v1

Image data from 18 Sep 2023, taken on-site at the IAS Hakos Observatory, Namibia. The spiral galaxy NGC 1097 in Fornax with a back then new type II supernova 2023rev, discovered on 08 Sep 2023. So only 10 days old in this image (see marker), or 45 million years, depending on the perspective.
