Bannister, N. Tanvir (U. Leicester) report on behalf of larger GRB
collaboration:
The 2-m Faulkes Telescope South observed the field of GRB 080413B
(trigger=309111, Stamatikos et al. GCN 7598) starting 8.7-hr after the
trigger time.
We detect the optical afterglow (Stamatikos et al. GCN 7598, Kruehler et al.
GCN 7599, Antonelli et al. GCN 7600) and measure the following magnitudes:
Filter T_mid(hr) Exposure(s) Mag
----------------------------------------------------------------------
R 8.74 30 19.00 +/- 0.15
I 8.90 640 18.91 +/- 0.05
I 9.20 1080 19.15 +/- 0.05
I 9.54 1080 19.22 +/- 0.06
