Xuehui Mao, Wei Gao, Yi Ding, Mi Zhang and Xing Gao report/s the discovery of a new astronomical transient.

IAU Designation: SN 2019wep
Discoverer internal name: PSP19F
Coordinates (J2000): RA = 11:04:36.990 (166.154125) DEC = +45:58:39.50 (45.977639)
Discovery date: 2019-12-07 23:16:30.000 (JD=2458825.4697917)

Potential host galaxy: PGC33464

Remarks: Xuehui Mao, Wei Gao, Yi Ding, Mi Zhang and Xing Gao, report the discovery of a possible supernova (mag approximately 18.2) on several 40-s survey images (limiting mag about 19.0) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Dec. 07.96979 UT using a unfiltered CCD ( + Celestron C14 Schmidt- Cassegrain telescope D=356-mm @f/6.9 ). The transient approximately located at R.A.=11h04m36.99s +45d58'39".5 (equinox 2000.0). Which is about 2.6" east and 27.6" south of the center of the PGC33464. Nothing is visible at this position on archival images taken on May. 30.65884 UT(limiting mag 19.0).
