We report a lengthy series of multicolor photometric observations of the most recent eruption (M31N 2023-12b) of the recurrent nova M31N 2008-12a that were obtained primarily using the 40-in telescope at the Mount Laguna Observatory (MLO). These data have been augmented with photometry conducted with
the 1.54-m Danish telescope at La Silla Observatory (DK154) and the 0.65-m telescope at Ondrejov (OND). For completeness, we also include our magnitude limits from 2023 Dec 05 UT reported in ATel #16362, where we clarify that the non-detection limits reported earlier are lower limits to the magnitudes.
