A. A. Miller, J. S. Bloom, and D. A. Perley (UC Berkeley) report:
We observed the optical afterglow of GRB080603B (Mangano et al., GCN
7794) with the 1.3m Peters Automated Infrared Imaging Telescope
(PAIRITEL) starting 7.66 hours post trigger on June 04, 2008 UT. We
detected the afterglow in a 2291 sec mosiac of 7.8 sec simultaneous
exposures in the J, H, and Ks filters. Preliminary photometry for the
afterglow in exposures beginning on Jun 04.14 UT yields J = 17.9 +- 0.1,
H = 17.2 +- 0.1, and Ks = 16.7 +- 0.15, calibrated to the 2MASS system.
