Kakazu (IfA, Hawaii) report:\n\nWe observed the localisation of GRB 080229 with the MAGNUM telescope +\nMIP dual-beam imager. We do not find any afterglow in the RIYJHK images\nwithin the XRT error circle (GCN #7343). We estimated the upper limits\nin JHK based on flux calibration with a nearby 2MASS star as follows:\n\n  Filter   t - t_GRB (hour)    Limit (mag)\n  J        +19.8               20.5\n  H        +20.7               20.0\n  K        +20.4               19.4\n\nThis message may be cited.",
