We report additional optical multi-colour photometry of the ongoing 2015 eruption of the fast recurrent nova M31N 1963-09c (see ATels #8242, #8238, #8235, #8234, #8233 and CBAT TOCP). The observations were conducted with the 0.9-m SARA-North telescope at Kitt Peak National Observatory on Nov 2-3, 2015. The photometric data was obtained in Bessel filters (B, V, R and I). One exposure per BVRI filter was taken on November 2, while November 3 received a higher cadence coverage. The nova is found to decline significantly on short time scales in all colour bands.
