We are conducting a long-term monitoring campaign of the optical and near-IR magnitudes of gamma-ray bright blazars using the SMARTS 1.3m telescope and ANDICAM instrument. We report a continued increase in optical and IR magnitudes of the blazar 3C 454.3, which has been reported in outburst in optical, IR, and gamma-rays since 31 Oct 2010 (Atel #2988, ATel #2995, ATel #3003, ATel #3005). Observations performed on UT 2010 November 10 show B=14.29, V=13.71, R=13.17, J=11.50, and K=9.83. Typical errors for our differential photometry are ~0.02 magnitudes in the optical and 0.05 magnitudes in the IR. Data for this source are available at
