AT 2023prq: A Classical Nova in the Halo of the Andromeda Galaxy

Abstract

The classical nova, AT 2023prq, was discovered on 2023 August 15 and is located at a distance of 46 kpc from the Andromeda Galaxy (M 31). Here we report photometry and spectroscopy of the nova. The 'very fast' ($t_{2,r^{\prime }}\sim 3.4$ d) and low luminosity ($M_{r^{\prime }}\sim -7.6$) nature of the transient along with the helium in its spectra would indicate that AT 2023prq is a 'faint-and-fast' He/N nova. Additionally, at such a large distance from the centre of M 31, AT 2023prq is a member of the halo nova population.
