Hoyes, University of Chicago, on behalf of the\nAstrophysical Research Consortium (ARC), report:\n\n\"We made near-infrared observations (GCN #39, IAUC 6860)\nof the SAX NFI error box for GRB 980329 (IAUC 6853, 6854)  \nbetween Apr. 1.167 UT and Apr. 1.277 UT, using the GRIM II instrument \nmounted on the ARC 3.5-m telescope at Apache Point Observatory.\nWe find no detectable object, down to a limiting J magnitude of 20.9 +/- 0.5\n(1 sigma) at the position R.A. = 7h02m38s.02, Decl. = +38o50'44\" (J2000.0) of\nthe variable radio source VLA J0702+3850 proposed by Taylor et al. (GCN #40) \nto be the radio afterglow from GRB 980329. The measurement by Mannuci et al. \n(GCN #46) of a magnitude J = 19.2 (+0.8,-0.5) object at the position\nof the radio source at epoch Mar. 29.84-29.86 UT implies\nthat this object dimmed by J magnitude 1.7 +/- 0.9 \nduring a period of approximately 2.4 days.\"\n\nThis report is citable.",
