TITLE: GCN CIRCULAR NUMBER: 9780 SUBJECT: GRB 090812: WIRO NIR upper limit DATE: 09/08/12 20:06:03 GMT FROM: Jay Norris at U. of Denver Alexander Kutyrev (CRESST/UMCP/GSFC), Jay Norris (U. Denver), report on behalf of the Goddard/U. Wyoming NIR camera collaboration. We observed the afterglow position of GRB 090812 as reported by Cenko (GCN Circ. 9769) with the 2.3-meter WIRO telescope and the Goddard NIR camera, commencing 10:28 UT, 4.4 hrs after the Swift trigger (Stamatikos et al., GCN Circ. 9768). Using stacked J-band images with a total exposure time of 1360 s, via comparison with two adjacent 2-MASS stars, we derive the following 3 sigma upper limit for the afterglow:        Tmid (UT)    Mag         10:46     J-band > 21.2
