report on behalf of the REM team:
The robotic 60-cm REM telescope located at La Silla (Chile) observed
automatically the field of the GRB 080218B (Schady et al., GCN 7314).
A preliminary analysis of the first set of H and K-band exposures
does not reveal any afterglow candidate inside the refined XRT error
box (Osborne et al., GCN 7320). The 3sigma upper limits of our images
are H > 13.7 about 2 minutes after the burst and K > 12.6 about 8
minutes after the burst (calibrated against the 2MASS catalog).
Further analysis is in progress.
