We report multicolor (BVRI) photometry of the recurrent nova M31N 2008-12a obtained near the peak of its most recent eruption (ATels #12177, #12179). The data, which were acquired with the CCD imaging camera on the 40-inch reflector at San Diego State University's Mount Laguna Observatory, yielded the following magnitudes:
