Hopkins, Arizona. Observations\nbegan at 2011-Feb-05 05h14m03s UT, ~3.2 hours after the Swift trigger.\n In  mosaics (effective exposure time of 0.50 hours) taken\nsimultaneously in the J, H, and Ks filters, we detect a source at the\nposition of the optical afterglow (Klotz et al., GCN 11630; Schaefer\net al., GCN 11631; Mundell et al., GCN 11633).\n\nThe preliminary photometry yields:\n\npost burst\nt_mid (hr) exp.(hr) filt  mag    m_err\n3.59       0.50     J     16.74  0.05\n3.59       0.50     H     15.81  0.05\n3.59       0.50     Ks    15.19  0.07\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.  Observations are continuing.",
