Valentini, Osservatorio Astronomico di Teramo, \nItaly, on behalf of a larger collaboration report:\n\n\"We observed the Optical Transient candidate of GRB 010222 reported \nby Handen, GCN #961 and McDowell et al., GCN #963 in J and K band \nwith the AZT-24 1.1-meter telescope at Campo Imperatore (AQ).\n\nThe J-band observation started at February 23.0078 UT and the field\nwas imaged for a total exposure time of 2200 sec. A point-like source\nwas observed in a position consistent with the OT position (GCN #961,\n#963). The source was detected with a S/N=10 and had a magnitude of\nJ=18.7+/-0.1. Another J-band observation started at February 23.1674 \nand the field was imaged for a total exposure time of 2200 sec. The \nsource was still detected at a S/N=5 and had a magnitude of J=19.3+/-0.2\n\nThe K-band observation started at Feb. 23.0681 UT and the field was\nimaged for a total exposure time of 2700 sec. The source was detected \nwith a S/N=8 and had a magnitude of K=17.4+/-0.3. \n\nThe J-band images are posted at\nhttp://argos.mporzio.astro.it/angelo/grb010222/\n\nThis message is citable.\"",
