Following ATel #8166, we obtained a 300sec R-band image at the location of MASTER OT J000008.72-334156.5 with DEIMOS mounted on the Keck 2 telescope on 2015-10-18 UT and found a point-like source with R=21.7 mag. We also noticed a source at the same location in WISE with W1=16.6 mag. Therefore, we conclude that MASTER OT J000008.72-334156.5 is probably a galactic M-star flare. The R-W1 color corresponds to a M5V-M6V star.
