NGC 2674 - Detail
SN 2020eqv (Type 1a) (= ASASSN-20dk) discovered 2020/03/21.310
by All Sky Automated Survey for SuperNovae (ASAS-SN)
Located 0".0 east and 0".0 north of the center of NGC 2674
(Rochester Supernova site | Discovery image | )

Image below (2020-04-24.892) was taken 34.58 days after discovery of SN 2020eqv
Centered close to the nucleus of the host galaxy it is not possible to resolve the SN directly.
Without an equivalent pre-SN archival image, it is not possible to identify any brightening of the galaxy
that could otherwise potentially confirm the presence of a supernovae.

Calibrated magnitude of host galaxy + possible SN in image below is +14.91
This might be compared with the magnitude of galaxy in a later post-SN image
(Comparison with catalog magnitude is inclusive :
NGC 2674 catalog mag +14.9 , NGC 2674 / PGC 24785 catalog mag +15.8)
