Ohta (Kyoto Univ.) and M. Akiyama (Subaru) report:\n\nWe have imaged the central region of the error circle of\nGRB 020331 with the SQIID equipped to KPNO 2.1m telescope.\nThe field is centered on 13h16m22.7s and -17d55'23\" (J2000)\nwith a field of view of about 5'x5'.\nThe J-, H-, and K-band images were taken simultaneously\nat 7:06 (Apr 1st) (UT).  A total integration time is 15min \nfor each band.\nWe have found the following two NIR objects that are not seen \nin the Digitized Sky Survey, APM catalog, and 2MASS images.\n \n#1 13h16m29.5s -17d55'08\" (J2000), J=17.7, H not measurable, K=16.8 \n#2 13h16m23.2s -17d56'11\" (J2000), J=17.6, H=17.2, K=16.8 \n \nAccuracy of the coordinates is about 0.5\". \nPhotometry was roughly made using 2MASS objects   \nexposed in the same frame; accuracy seems to be less than\n0.1 mag (J-band), 0.3 mag (H-band), and 0.5 mag (K-band).\nThere is a possibility that these objects are not seen in\nthe POSS merely because they are red objects. \nIf one of them will fade, it should be a candidate of the\nafterglow of the GRB.  Further NIR observations are desirable. \n \nThis message may be cited.",
