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.

I took a few pics on this target and it seems the suspected star was not reported in existing database. Below is a zoom-in with annotation with UCAC3 and USNO-B1 catalogs with stars ranging from 12-18 mag, and to me there is no mentioning of the suspected star. I measured it to be roughly RA:13°56'06.8" and DEC: +05°15'15.7" under J2000.

The position of 13:57:06.000 +05:09:12.00 corresponds well ESE of the galaxy.  However, the description of 6.6" SW of center appears to match up to a superposed star which shows up in the planetarium software Guide 9.1 and which is listed as 4UC477-053092 at magnitude 12.8.  A 2MASS image shows a star very close WSW of the core.
