Rau (Caltech) report on behalf of a larger\ncollaboration:\n\nWe have imaged the field of GRB070724B (Feroci et al., GCN 6668), the\nfirst GRB detected by SuperAGILE, with the automated Palomar 60-inch\ntelescope.  Observations consisted of 5 x 180 s images in the i' filter at\na mean epoch of approximately UT 06:46:30 on 2007 July 26 (~ 31.3 hours\nafter the burst).  We do not detect any sources inside the error circle of\nthe likely XRT afterglow (Romano et al., GCN 6675) to a limiting\nmagnitude of i' > 21.0 (calculated with respect to several USNO-B stars\nin the field).",
