The 2-m Faulkes Telescope North automatically began observing
GRB 121211A (Mangano et al. GCN Circ. 14057) on Dec 11 2012,
13:50:46 UT corresponding to 224 seconds post burst trigger. We confirm
the presence of a fading source at the optical afterglow candidate position
reported by Mangano et al. GCN Circ. 14057. In the first 3x10 s exposure,
we measure a preliminary R magnitude of 17.9 +- 0.3, calibrated against
nearby USNO-B1 stars.
