We report optical photometric observations of the 2017 eruption (see ATels #11116, #11117, #11118, #11121) of the recurrent nova M31N 2008-12a (Henze et al. 2014, 2015a, 2015b; Darnley et al. 2014, 2015, 2016). The data were obtained using the BESSEL B, V, R, I filters between 2018 Jan 01.01 UT - 2018 Jan 03.20 UT with the 0.9 m SARA telescope equipped with ARC CCD camera(Keel et al. 2017), located at the Kitt Peak National Observatory, Arizona. The derived magnitudes were calibrated with the standard stars in the field of this nova. The total exposure time for each reported magnitude varied between 5 - 60 minutes.
