We report the discovery of a possible nova in M31 at 87.58 arcmin from the nucleus based on observations
with the Wide Field Camera of the Isaac Newton Telescope on October 19 2019 using the WFC Sloan g, r and i and the
RGOZ filters. The object is well detected in all the bands. This transient has also been detected by ZTF (ZTF19acfsteg) and reported to TNS (AT 2019stm),
with the first detection in g-band on 2019 October 18 03:50:36 UT. The combined ZTF and INT WFC light curve shows that the flux is rising fast,
with delta (m) / delta (t) in g-band of 0.77 mag/day.
The object position on the WFC images, calibrated using the Gaia DR2 catalog is:
RA (J2000) = 00:40:05.053, Dec (J2000) = +39:53:57.28
There are no known catalogued sources at this sky position. We designate the object PNV J00400505+3953573.
The INT Wide Field Camera magnitudes, calibrated using PanSTARRS-1 DR2 are:
g = 18.55 +/- 0.01 (2019 October 19 22:39:56.1 UT), 180 seconds
r = 18.63 +/- 0.02 (2019 October 19 22:44:08.3 UT), 180 seconds
i = 18.77 +/- 0.03 (2019 October 19 22:48:38.5 UT), 180 seconds
z = 19.35 +/- 0.07 (2019 October 19 22:53:01.8 UT), 180 seconds
We encourage additional photometric follow-up and spectroscopic observations of this possible nova in M31.
Based on observations made with the Isaac Newton Telescope operated on the island of La Palma by the Isaac Newton Group of Telescopes in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofisica de Canarias.
