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.
