Mi Zhang and Xing Gao report/s the discovery of a new astronomical transient.

IAU Designation: AT 2019olu
Discoverer internal name: XM14MZ
Coordinates (J2000): RA = 00:57:10.190 (14.292458) DEC = +62:03:55.90 (62.065528)
Discovery date: 2019-08-23 15:32:58 (JD=2458719.1478935)


Remarks: Mi Zhang and Xing Gao, report the outburst of a variable star candidate (mag approximately 15.3) was discovered on severl 60-s survey images (limiting mag about 19.0) taken by Xing Gao in Xingming Observatory Sky Survey (XXX) around Aug. 23.64789 UT using a unfiltered CCD ( + 0.5-m f/4 reflector + CCD ). The transient approximately located at R.A.=00h57m10.19s +62d03'55".9 (equinox 2000.0). Which is about 66.6" west and 52.2" north of the center of the TYC 4021-523-1 (star). The variable star candidate on Aug. 22.64928 UT was 17.1 (limiting mag 19.0).
