Testa, S.D. Vergani,  F. Vitali   report on behalf of the REM team:


The NIR afterglow is detected by the REM telescope at coordinates:

RA = 23:40:17.1
DEC = 31:46:43.6

with H~13.8 at 4:18:12 UT.

The source is NOT in the XRT error circle, although rather close to  
it. The source is bright, and not present in the 2MASS or USNO  
catalogues. The source is compatible with that reported by Rykoff et  
al. (GCN 6987).

Further observations are in progress.
