G. Ghirlanda, G. Ghisellini, C. Firmani, F. Tavecchio 
(Oss. Astron. di Brera) report:

GRB 050603, with a redshift of 2.821 (Berger and Becker, GCN 3520), 
fluence and spectral parameters as measured by Konus-Wind 
(Golenetskii et al., GCN 3518), requires an achromatic break 
at t = 7 +/- 3 days (after trigger) to be consistent with the 
"Ghirlanda" relation between the collimation corrected
energy and Epeak. A plot can be seen at: 
http://www.merate.mi.astro.it/~ghirla/deep/blink.htm .
We urge observations in order to verify this prediction.
