Wyoming NIR camera collaboration.\n\nWe observed the afterglow position of GRB 090812 as reported by Cenko\n(GCN Circ. 9769) with the 2.3-meter WIRO telescope and the Goddard\nNIR camera, commencing 10:28 UT, 4.4 hrs after the Swift trigger\n(Stamatikos et al., GCN Circ. 9768).\n\nUsing stacked J-band images with a total exposure time of 1360 s,\nvia comparison with two adjacent 2-MASS stars, we derive the following\n3 sigma upper limit for the afterglow:\n\n������ Tmid (UT)��� Mag\n\n������� 10:46���� J-band > 21.2",
