ATLAS21dfz (AT2021biz): discovery of a candidate SN in NGC 4227 (97 Mpc)
Abstract
Here we report the ATLAS discovery of the transient ATLAS21dfz (AT2021biz) in galaxy NGC 4227 at magnitude m_o = 18.34 +/- 0.16. At a distance of 97 Mpc (redshift independent, from NED), the transient was discovered on MJD = 59243.54 (2021-01-29.54) with an absolute magnitude of M = -16.61 +/- 0.16. The last non-detection through forced photometry was on MJD = 59238.56. Spectroscopic classification is encouraged.
