We report the following photometry of M31N 2008-12a obtained during its recent eruption. Observations were made using the 40-in telescope at San Diego State University's Mount Laguna Observatory (MLO), augmented by measurements using a Luminance filter with the 0.43m CDK astrograph (iTelescope.net, New Mexico), and the 0.6m telescope of the Robotic Burke-Gaffney Observatory (BGO).
