Koviak observed the field of GRB 011121\n(GCN #1149) with the du Pont 2.5m telescope at Las Companas Observatory.\nIn a single 90 sec sky-subtracted observation in J-band, a source at the\nposition of Stanek's transient (GCN ##1150,1151) is strongly detected\nat the 10-sigma level.  We estimate the magnitude as J ~ 16 mag.\nReductions of the nearly 2 hours of J and Ks band imaging are in progess,\nbut clearly the source is bright in the NIR.\n\nGiven the large Galactic extinction towards this source, we strongly\nencourage NIR observations of this afterglow.  Further observations\nare in progress.\n\nThis message may be cited.",
