behalf of the REM team:
The robotic 60-cm REM telescope located at La Silla (Chile) observed
automatically the field of the GRB 080913 (Schady et al. GCN 8217) on
Sep 13 starting about 6 min after the burst. Observations were carried
out at high airmass. Coadding a series of 10s, 30s and 60s exposures, at
a mean t-t0 ~ 40 min we do not see the object reported by Rossi et al.
(GCN 8218) or any other afterglow candidate inside the refined XRT error
box (Beardmore et al.; GCN 8219) down to J > 17.1, H > 17.2 and K > 15.8
