J-, H-, and Ks-band photometry of the optical afterglow (Peterson and
Price GCN 1985, Torii GCN 1986) of GRB030329 (Vanderspek et al. GCN
1997) were obtained on the nights of 2003 Apr 29 and 30 at GAO, Gunma,
Japan, using the 1.5-m telescope and the IR Camera. The observation
started at 13:50 UT (133 min after the GRB trigger).
Our preliminary J-band magnitudes (rough estimate of typical error is
0.1 mag) of the afterglow are given below:
