"We are observing the field of GRB 080603B (Mangano et al. GCN 7794)
with the recently installed 60cm robotic telescope BOOTES-2/TELMA in
M�laga (south Spain). The first observations (120s each, with the
r'-band filter) were obtained starting at 20:31 UT (i.e. 51 min after
the onset of the event). We detect the optical afterglow (Rujopakarn et
al. GCN 7792, Mangano et al.) with 17.3 mag, based on a preliminary
calibration using USNO-A2.0. We also confirm the early plateau phase
reported by Klotz et al.(GCNC 7795). From our last frame taken at 22:30
UT we derive a 0.3 mag decay. Further images (in g'r'i'Z filters) are
on their way. Spectroscopic observations are encouraged."
