Observations began at\n2012-03-27 09:25:19 UT, ~32.1 hours after the Swift Trigger.  In  mosaics\n(effective exposure time of 1.31 hours) taken simultaneously in the J, H,\nand Ks filters, we detect a source at the optical afterglow location (Klotz\net al., GCN 13107; LaCluyze et al., GCN 13109; Guidorzi et al., GCN 13111;\nWalker et al., GCN 13112; Kuin et al., GCN 13114; Im et al., GCN 13117;\nHentunen et al., GCN 13119; Urata et al., GCN 13121; Zhao et al., GCN\n13122; Soulier, GCN 13126; Jang et al., GCN 13139; Quadri et al., GCN\n13142).\n\nThe preliminary photometry yields:\n\npost burst\nt_mid (hr) exp.(hr) filt  mag    m_err\n33.58      1.31     J     17.5   0.1\n33.58      1.31     H     16.7   0.1\n33.58      1.31     Ks    16.0   0.2\n\nAll magnitudes are given in the Vega system, calibrated to 2MASS.
