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 FROM: Daisuke Yonetoku at Kanazawa U D. Yonetoku, T. Murakami, H. Kodaira, S. Okuno, S. T. Kidamura (Kanazawa Univ.) and Y. Kobayashi (NAOJ) 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).
