The M31 nova candidate PSP23N (AT 2023yoa) was discovered by Xu et al. (XOSS) on 2023-11-27 19:56:16 UT at a magnitude of 16.2 (Clear).
It was spectroscopically classified as a M31 nova by Balcon (Belluno A.O. ISSP) and reported to TNS. Zhang (TNS comment) and Shafter et al. (ATel #16354)
report that the nova position is close to PNV J00430954+4115399 (M31 2013-10c), discovered by the Lick Observatory Supernova Search (LOSS) and reported to CBAT
(see also Hornoch et al. ATel #5468 and Hornoch et al. ATel #5503), and is likely a recurrent nova.
Here, we report follow-up imaging and detection of this nova with the Las Cumbres Observatory 40 cm telescope, equipped with an SBIG camera,
at the Las Cumbres Observatory node at Haleakala, in a 180 sec observation in the SDSS g' filter on 2023-11-28 05:23:01 UT, at g' = 16.41 +/- 0.15.
We measure a position of RA (J2000)= 00:43:09.528, Dec (J2000) = +41:15:40.25, calibrated precisely with Gaia DR3 stars, that is consistent with M31 2013-10c (PNV J00430954+4115399).
Further observations are strongly encouraged.
This work makes use of observations from the Las Cumbres Observatory global telescope network (program IAC2023B-001) and is based on observations made with the Las Cumbres Observatory education network telescopes that were upgraded through generous support from the Gordon and Betty Moore Foundation. These observations and analysis are part of a course in Astrophysical Techniques of the Master in Astrophysics of the Astrophysics Department of the University of La Laguna and the Instituto de Astrofisica de Canarias (Tenerife, Spain). We thank David Bishop for his very useful compilation of extragalactic novae and supernovae.
