(Gunma Astronomical Observatory) report:
The position of GRB 100219A (Rowlinson et al., GCN 10430) was observed
with the 150 cm telescope of Gunma Astronomical Observatory. Starting at
16:06:16 UT on Feb.19 (0.84 hour after the trigger), both Rc and Ic
frames were acquired for sets of 5 x 3-min exposures.
Inside the XRT error circle (Evans et al., GCN 10437), we detected the
optical counterpart reported by Jakobsson et al. (GCN 10438), Kruehler
et al. (GCN 10439), and Kuroda et al. (GCN 10440) in Rc and Ic stacked
images. We estimated the Rc and Ic magnitudes relative to USNO-B1.0 R2
and I magnitudes, respectively.
