TITLE: GCN GRB OBSERVATION REPORT
NUMBER: 4459
SUBJECT: GRB 060108: ISAS early observations and near IR upper limit
DATE: 06/01/10 00:47:40 GMT

on behalf of the Kanazawa team:
We have observed the field of GRB 060108 (Oates et al., GCN 4443;
Sakamoto et al., GCN 4445) with H and Ks-bands using the 1.3m telescope
on the roof top of ISAS, Japan. The observation was started 12 minutes
after the BAT trigger. We found no new source down to a limiting
magnitude of H = 15.8 and Ks = 15.8 (5 sigma upper limit) within
the position of the XRT error circle (Page et al., GCN 4453).
