A. N. Morgan, D. A. Perley, C. R. Klein, and J. S. Bloom (UC Berkeley) report:
We observed the location of GRB 100513A (Baumgartner et al., GCN 10746)
with the 1.3m PAIRITEL located at Mt. Hopkins, Arizona. Observations
began at 2010-05-13 03:03:07 UT, ~0.77 hours after the Swift Trigger,
after sunset. In mosaics (effective exposure time of 0.92 hours)
taken simultaneously in the J, H, and Ks filters, we detect a NIR
source within the XRT error circle at a location:
11:18:26.8, +03:37:40 (J2000)
The preliminary photometry yields:
post burst
t_mid (hr) exp.(s) filt mag m_err
0.93 772 J 17.7 0.1
All magnitudes are given in the Vega system, calibrated to 2MASS. No
correction for Galactic extinction has been made to the above reported
values.

was change to the Baumgartner reference.]
