Roth (LCO) report:\n\n\"We observed the position of GRB 071227 (GCN #7148) with the IMACS \ninstrument on the Magellan/Baade telescope starting on 2007 Dec. 28 at \n03:52 UT (7.7 hours after the burst).  In a 300-sec R-band exposure we \ndetect a single galaxy within the XRT error circle, coincident with the \nposition of the UVOT source (GCN #7150).  This object is also visible in \nthe DSS.  The galaxy has spiral, edge-on morphology, and a total magnitude \nof R=19.3 mag.  There are no other sources within the XRT error circle to \na 3-sigma limiting magnitude of R~22.3 mag.\"",
