We report multicolor follow-up of the recurrent nova M31N 2008-12a using the 0.60-m Ningbo bureau of Education and Xinjiang observatory Telescope (NEXT) located at Xingming Observatory, Mt.Nanshan, Xinjiang, China. All multicolor images were obtained between 2022-12-03 and 2022-12-06 in g', r', and i' filters. All photometric results were calibrated using nearby secondary standard stars in the field (Darnley et al., 2016). Since December 5th 2022, M31N 2008-12a has been invisible in images because of its rapid decay in brightness, cloudy weather at the site, and strong moonlight.
