TITLE: GCN CIRCULAR NUMBER: 7662 SUBJECT: GRB 080430: Shallow decay DATE: 08/05/02 02:51:50 GMT FROM: Antonio Deugarte at IAA-CSIC A. de Ugarte Postigo (ESO), C.C. Thöne (Dark), F. Aceituno (IAA-CSIC), Nicolaas E. Groeneboom, Øystein Rudjord, Jostein R. Kristiansen (Univ. Oslo) 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.
