Emmanuel Conseil report/s the discovery of a new astronomical transient.

IAU Designation: SN 2020epi
Coordinates (J2000): RA = 12:22:08.760 (185.5365) DEC = +06:06:01.30 (6.100361)
Discovery date: 2020-03-19 02:53:00.000 (JD=2458927.6201389)

Potential host galaxy: PGC 40043
Host redshift: 0.024562

Remarks: Emmanuel Conseil, on behalf of the TAROT collaboration, reports the discovery of a probable supernova in the galaxy PGC 40043 located at R.A = 12 22 08.76 and Decl = +06 06 01.3 (J2000.0), which is 13.5" E and 13.1"S from the nucleus of PGC 40043. The transient was visible on 2 images (120s exposures), taken by the TAROT Calern telescope on 2020-03-19 at 02h53 UTC, at magnitude 18.5 (Red filter, limiting R mag 19.0). Nothing was visible at this location on previous images taken by the same telescope on 2020-03-16 at 03h08 UTC (limiting R mag 18.5).
