on behalf of a larger European GRB collaboration
report:
"We have just obtained a 15-minute R-band exposure centred at
the GRB 000301C error box (Smith et al. GCN#568) starting at
01:15 UT on 4 March 2000 with the 1.23 m telescope at the
German-Spanish Calar Alto Observatory (CAHA).
Using the stars A-D of Garnavich et al. (GCN #573) we derive
R = 20.46 +/- 0.09 for the optical counterpart reported by Fynbo
et al. (GCN #570). When combining this value with the measurements
by Fynbo et al. (GCN #576) and Halpern et al. (GCN #578) the
power-law decline exponent becomes alpha = -1.27 +/- 0.20."
This message is quotable.
