Using the ATLAS (Tonry et al. 2018, PASP, 130, 064505; Smith et al. 2020, PASP, 132,085002) forced photometry tool (https://fallingstar-data.com/forcedphot/, Shingles et al. 2021,2021TNSAN...7....1S), we confirm the ATLAS detection of the M31 nova candidate AT 2022zhv (XM87MZ, PNV J00422610+4113390)
discovered by Mi Zhang and Xing Gao (Xingming Obs.) and reported to TNS.
Hornoch et al. (ATel #15738) have also reported the independent discovery of this probable nova in M31 using the 0.65-m telescope at Ondrejov (OND) and the 1.0-m telescope at Mount Laguna Observatory (MLO) and designated it as M31N 2022-11a.
The ATLAS > 5-sigma forced photometric detections in the ATLAS orange filter at the position reported by Hornoch et al., R.A. = 0h42m26s.11, Decl. = +41o13'38".9 (equinox 2000.0), are (MJD m +/- dm): 59885.360388 18.424 +/- 0.173; 59885.363159 18.115 +/- 0.150; and 59885.395456 18.274 +/- 0.169.
We encourage photometric and spectroscopic follow-up observations.
