ATLAS23xva (AT2023abdg): discovery of a fast rising candidate SN in NGC 7421 (28 Mpc)
Abstract
Here we report the ATLAS discovery of the transient ATLAS23xva (AT2023abdg) in galaxy NGC 7421 at magnitude m_o = 14.50 +/- 0.01. At a distance of 28 Mpc, the transient was discovered on MJD = 60302.06 (2023-12-24.06) with an absolute magnitude of M = -17.74 +/- 0.01. The last non-detection through forced photometry was on MJD = 60291.81. Forced photometry indicates that the transient is rapidly rising. Spectroscopic classification is encouraged.
