The remarkable recurrent nova M31N 2008-12a, which has a recurrence time of order 1 year, has just been observed to have its 6th recorded outburst starting on 2014 October 2.903 (ATel #6527, #6532, #6535, #6537, #6540). Here, we report multicolor photometry of this most recent outburst obtained with a Loral 2048 X 2048 CCD imager at the Cassegrain focus of the Mount Laguna Observatory 1.0-m reflector. The observations, which were obtained on the night of 04 October 2014 UT (~1.3 days after discovery of this most recent eruption), resulted in the following magnitudes:
