Fox (Caltech) report on behalf\nof the Carnegie-Caltech-NRAO collaboration:\n \n\"On 2005, February 24.09 UT we obtained near-infrared spectra with GNIRS\non the Gemini-south telescope of the NIR afterglow of GRB 050219b,\nidentified in images from the Las Campanas 100-inch telescope (see also\nGCN 3064). As reported in GCN 3064 (also GCN 3052: UVOT limits), the NIR\nafterglow is significantly brighter than optical limits obtained\ncontemporaneously, suggesting a large dust extinction or a high redshift\n(z>5) origin.\n \nUsing Director's Discretionary time we obtained a total of 4800 sec on\nsource in the cross-dispersed mode which covers the range of 1-2.5 microns\nin six echelle orders (R~1700).  No continuum or emission lines were\ndetected in the combined 2-d spectrum.\n \nWe thank Phil Puxley, Gemini South Associate Director, for the allocation\nof DD time, and Claudia Winge for extensive help with the Phase I/II setup\nand the observations.\"",
