"We observed the optical afterglow of GRB070419A (Stamatikos et al
#6302, Chornock et al #6304, Cenko et al #6306, Nishiura et al. #6308
and Rol et al #6309) with the Lulin One-meter Telescope started from
11:49 UT. The afterglow at 2.0 hours after the burst is visible in our
R-band combined image with R = 21.8+/-0.3 (compared with USBO-B1.0 catalogue)."

Further observations and analysis are in progress.
