TITLE: GCN CIRCULAR NUMBER: 7404 SUBJECT: GRB 080229: NIR upper limit DATE: 08/03/11 03:23:10 GMT FROM: Takeo Minezaki at U.of Tokyo/Astro T. Minezaki (IoA, Tokyo), P.A. Price (IfA, Hawaii), Y. Yoshii (IoA, Tokyo), L. Cowie (IfA, Hawaii) and Y. Kakazu (IfA, Hawaii) report: We observed the localisation of GRB 080229 with the MAGNUM telescope + MIP dual-beam imager. We do not find any afterglow in the RIYJHK images within the XRT error circle (GCN #7343). We estimated the upper limits in JHK based on flux calibration with a nearby 2MASS star as follows: Filter t - t_GRB (hour) Limit (mag) J +19.8 20.5 H +20.7 20.0 K +20.4 19.4 This message may be cited.
