AT2022UZ: SUSPECTED NOVA In M31

PRE-DISCOVERY, George Carey, UK Nova/Supernova patrol reports :
Despite the run of clear skies we have had lately, I missed detection of: 

AT2022uz (= XM63MZ) (= PNV J00430928+4116013)

The sky has been clear but hazy, and this suspected nova has been around
magnitude 19 to 20 which is just on the limit of my detection ability.

Discovery was on the 16th January, I can faintly see it going back to 5th
January.
I posted a prediscovery announcement and image on TNS.

ORIGINAL DISCOVERY:
TNS Astronomical Transient Report o. 134135
Sender: Mr. Mi Zhang
Reporting Group: XOSS
Mi Zhang, Xing Gao (Xingming Obs) report/s the discovery of a new
astronomical transient.

IAU Designation: AT 2022uz; Discoverer internal name: XM63MZ
Coordinates (J2000): 
RA = 00:43:09.280 (10.788667) DEC = +41:16:01.30 (41.267028)
Discovery date: 2022-01-16 14:05:59.136 (JD=2459596.08749)
Potential host galaxy: M31

Remarks: Mi Zhang, Xing Gao (Xingming Obs), report the discovery of a
possible nova at 19.7 Gmag on several 300-s survey image (limiting mag about
20.5 G) taken by Xing Gao at Xingming Observatory "#"3 (N88) around Jan.
16.58749 UTC using a unfiltered CCD (+ 0.6-m f/8 Ritchey-Chretien
telescope). The transient approximately located at RA= 00h43m09.28s,DEC =
+41d16m01.3s (equinox 2000.0). Which is about 281.4" east and 7.2" south of
the center of the NGC224(M31). Nothing is visible at this position on
archival images. Images can be found at:
