A. N. Morgan & C. R. Klein (UC Berkeley) report:
We observed the field of GRB 130610A (Cummings et al., GCN 14842) with the
1.3m PAIRITEL located at Mt. Hopkins, Arizona. Observations began at
2013-Jun-07 03h35m37s UT, 0.39 hr after the Swift Trigger. In mosaics
(effective exposure time of ~5.85 minutes) taken simultaneously in the J,
H, and Ks filters, we detect the optical afterglow (Cummings et al., GCN
14842; Melandri et al., GCN 14843; Trotter et al. GCN 14844). The
preliminary K-band reduction is corrupted.
The preliminary photometry yields:
post burst
t_mid (hr) exp.(m) filt mag m_err
0.47 5.85 J 17.49 0.16
0.47 5.85 H 16.95 0.20
Observations are ongoing. All magnitudes are given in the Vega system,
calibrated to 2MASS. No correction for Galactic extinction has been made to
the above reported values.
