We report optical photometric observations of the 2019 eruption (see ATels #13269, #13273, #13279, #13281,#13290) of the recurrent nova M31N 2008-12a (Henze et al. 2014, 2015a, 2015b,2018; Darnley et al. 2014, 2015, 2016). The data were obtained between 2019 Nov 7.0 UT - Nov 08.0 UT with the 0.9 m SARA telescopes equipped with ARC CCD camera (Keel et al. 2017, located at the Kitt Peak National Observatory (SARA-KPNO), Arizona. The exposure times were 5 minutes each in BESSEL filters; B, V, R and I and data were taken during non-photometric conditions. The derived magnitudes were calibrated with the standard stars in the field of this nova.
