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.
