and Tapio Purismo (NOT) on behalf of a larger collaboration report:

We are continuing with the monitoring of the afterglow (Klotz et al. GCN
7646)
of GRB 080430 (Guidorzi et al., GCN 7647) with the 1.5m OSN telescope
(Sierra
Nevada Observatory) and the 2.5m NOT+MOSCA (Roque de los Muchachos
Observatory) in I band. During the first day of observations we observe a
steady
decay with a shallow slope of alpha ~ 0.6 (f ~ t^-alpha), being at a
magnitude of
I ~ 20.5 one day after the burst.

Further observations are encouraged. This message can be cited.
