E. Berger (Princeton), N. Morrell and M. Roth (LCO) report:
"We observed the position of GRB 071227 (GCN #7148) with the IMACS
instrument on the Magellan/Baade telescope starting on 2007 Dec. 28 at
03:52 UT (7.7 hours after the burst). In a 300-sec R-band exposure we
detect a single galaxy within the XRT error circle, coincident with the
position of the UVOT source (GCN #7150). This object is also visible in
the DSS. The galaxy has spiral, edge-on morphology, and a total magnitude
of R=19.3 mag. There are no other sources within the XRT error circle to
a 3-sigma limiting magnitude of R~22.3 mag."
