Texas) report on behalf of the ROTSE\ncollaboration:\n\nROTSE-IIIb, located at McDonald Observatory, Texas, responded automatically to\nINTEGRAL trigger #2073, GRB041219.  Our first 5-s exposure started at 01:44:11.6\nUT, 74 seconds after the start of the GRB, and 6 seconds after the trigger, and\nduring the GRB itself (GCN 2866).  Our unfiltered images were calibrated\nrelative to USNO A2.0. Comparison to DSS reveals no new sources to a limiting\nmagnitude of around 17.2.  Due to the low galactic latitude, field crowding is\na significant issue. Imaging is ongoing.",
