Observations began at 2011-Jan-20\n01h24m08s UT, ~3.1 hours after the Swift Trigger, under high airmass (~1.9),\nand continued until the source set beyond telescope limits.  In  mosaics\n(effective exposure time of 0.64 hours) taken simultaneously in the J, H,\nand Ks filters, we detect a source at the UVOT position (Troja et al., GCN\n11581).\n\nThe preliminary photometry yields:\n\npost burst\nt_mid (hr) exp.(hr) filt  mag   m_err\n3.78       0.64     J     17.9  0.2\n3.78       0.64     H     17.0  0.2\n3.78       0.64     Ks    16.2  0.2\n\nAll magnitudes are given in the Vega system, calibrated to 2MASS. No\ncorrection for Galactic extinction has been made to the above reported\nvalues.",
