Fox\n(Penn State), and Edo Berger (Carnegie), report on behalf of the\nCaltech-NRAO-Carnegie GRB collaboration:\n\n\"We have imaged the field of GRB 051021 (Yoshida et al., GCN 4116) with\nthe Wide Field Infrared Camera mounted on the Palomar 200\" Hale Telescope.\nOur images consisted of 9 x 120 s exposures taken in the Ks filter at a\nmean epoch of approximately 22 October 5:24 UT (~ 16 hours after the\nburst).  We find at best a marginal (< 3-sigma) detection at the location\nof the OT (Fox et al., GCN 4120).  Our 3-sigma limiting magnitude,\ncalculated with respect to several 2mass stars in the field, is\napproximately Ks > 19.0.\n\nWe note that under the standard afterglow model, our result is\ninconsistent with the J-band detection reported by Haislip et. al (GCN\n4127), and therefore calls into question the interpreration of GRB 051021\nas a high redshift event.\"",
