Jingyuan Zhao, Tianyu Tu, Jianlin Xu, Baixiang He, Zhangrui Xu, Mi Zhang and Xing Gao report/s the discovery of a new astronomical transient.

IAU Designation: SN 2019bqe
Discoverer internal name: PSP19B
Coordinates (J2000): RA = 09:59:39.940 (149.916417) DEC = +35:23:42.20 (35.395056)
Discovery date: 2019-03-07 19:26:10 (JD=2458550.309838)

Potential host galaxy: NGC 3074

Remarks: Jingyuan Zhao, Tianyu Tu, Jianlin Xu, Baixiang He, Zhangrui Xu, Mi Zhang and Xing Gao, report the discovery of a possible supernova (mag approximately 18.2) on severl 40-s survey images (limiting mag about 19.0) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Mar. 07.80984 UT using a unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9 ). The transient approximately located at R.A.=09h59m39.94s +35d23'42".2 (equinox 2000.0). Which is about 15.6" west and 8.1" north of the center of the NGC3074. Nothing is visible at this position on archival images taken on Feb. 28.82755 UT(limiting mag 19.0).
