Philip Hoyle report/s the discovery of a new astronomical transient.

IAU Designation: AT 2020leu
Coordinates (J2000): RA = 13:57:06.000 (209.275) DEC = +05:09:12.00 (5.153333)
Discovery date: 2020-05-24 00:00:00.000 (JD=2458993.5)

Potential host galaxy: NGC5363

Remarks: There is a possible supernova in NGC5363. Rough estimate of the magnitude is mag 13. Instrument used: 14" SCT. Location: Wooster, OH (40D 48' 33" N; 81D 57' 0" E). The SN is located approximately 6.6" SW of the center of NGC5363. Two images were taken, one at approximately 11 PM EDT on 5/24/2020 and the other at approximately the same time on 5/25/2020. There were no stars at this location in WIKISKY or the Digitized Sky Survey. The magnitude estimate was made using a star of similar brightness in my image(s) compared with the same star in Wikisky.
