Photometry results were V=16.65 and Ic=13.50 with 0.61-m f/6.5 CDK astrograph + FLI PL09000 CCD at SRO, Auberry, California. USA There is very red star at position reported. It might be flare of SIMBAD source LP 43-50 as Kenta Taguchi mentioned on his Twitter message (https://twitter.com/kentagch/status/1616247494991806464).
