S. B. Pandey, Rupak Roy and Brijesh Kumar (ARIES, NainiTal, India, on behal=
f of larger Indian GRB collaboration)
We observed Swift GRB 080430 with 1.04m telescope NainiTal starting ~20.0 h=
ours after the burst (Guidorzi et al. GCN 7647). Observations were performe=
d in R_c and I_c filters.
Photometry of one of the R_c frame (exposure time 1800s) shows theafterglow=
 around ~ 20.5 mag as reported in GCN 7646 and GCN 7648. The reported magni=
tude is determined in comparison to nearby USNO stars.
