Tokyo) report on behalf of the UH-MAGNUM GRB collaboration:\n\nWe observed the XRT position of GRB 050421 (Godet et al., GCN #3301)\nwith the automated MAGNUM telescope + MIP dual-beam optical-NIR imager,\ncommencing at April 21.57 UTC (9.4 hours after the GRB).  We obtained\n9x60 sec images in JHK, reaching limiting magnitudes of J ~ 20.3 mag, H\n~ 19 mag, K ~ 18.6 mag (from comparison with a single 2MASS star).  We\ndo not detect any afterglow candidate in the XRT error circle.\n\nThis message may be cited.",
