behalf of the REM team:


We started a refined analysis of the REM observations of GRB 080319B  
(GCN 7427, Racusin et al.). As already reported by Cwiok et al. (GCN  
7439 and 7445) the optical counterpart of this GRB was exceptionally  
bright at early time. We measured, about 1 min after the burst, R~6.4  
assuming R=11.20 for the USNO star at coordinates RA,DEC =  
14:31:23.61, 36:21:56.5. The source was already almost 2 mag fainter  
half a minute later. In the H band the source was H~5 around the same  
epoch.

Further analyses are in progress.
