A. A. Miller, J. S. Bloom, and D. A. Perley (UC Berkeley) report:
We observed the optical afterglow of GRB080603A (Paizis et al., GCN
7790; Gomboc et al., GCN 7788; Chornock et al; GCN 7789) with the 1.3m
Peters Automated Infrared Imaging Telescope (PAIRITEL) starting 18.89
hours post trigger on June 04, 2008 UT. We detected the afterglow in a
2927 sec mosaic of simultaneous 7.8 sec exposures in the J, H, and Ks
filters. Preliminary photometry for the afterglow in exposures beginning
on Jun 04.26 UT yields J = 18.9 +- 0.15, H = 17.9+- 0.15, and Ks = 16.8
+- 0.15, calibrated to the 2MASS system.
