We report late R-band photometry of the 2016 eruption (see ATels #9848,#9852,#9853,#9857,#9861,#9872,#9874 and #9881) of the recurrent nova M31N 2008-12a (Henze et al. 2014, 2015a, 2015b; Darnley et al. 2014, 2015, 2016). These data were obtained using the Danish 1.54-m telescope at La Silla (DK154) and the 0.65-m telescope at Ondrejov (D65). The R-band magnitudes were calibrated using 8 standard stars located in the field of the nova.

This work is based (in part) on data collected with the Danish 1.54-m telescope at the ESO La Silla Observatory. The 0.65-m telescope is operated jointly by the Astronomical Institute of ASCR and the Astronomical Institute of the Charles University of Prague, Czech Republic. It uses a Moravian Instruments G2-3200 CCD camera (with a Kodak KAF-3200ME sensor and standard BVRI photometric filters) mounted at the prime focus. We thank G. Mansir for sharing her observing time at the 1.54-m Danish telescope on Dec. 15th.
