GOTO detection of the M31 nova M31N 2008-12a
Abstract
We report the detection of the recurrent M31 nova M31N 2008-12a (ATel #14130) on 2020-10-30 19:58:11 (MJD 59152.83207), during its most recent outburst. In three visits between 19:58 to 23:35 with the Gravitational-wave Optical Transient Observer (GOTO) prototype on La Palma, each comprising a series of 3 90-s exposures in our wide (400-700 nm) L-band filter, we found the nova at an estimated g-band magnitude of 18.74+/-0.17 on average, based on cross-calibration against PanSTARRS DR1 photometry in ATLAS_REFCAT2 (Tonry et al. 2018).
