Fox report on behalf of the\nCaltech-NRAO-Carnegie GRB Collaboration:\n\nWe have imaged the error circle of GRB050504 (GCN 3348) with the automated\nPalomar 60-inch Telescope.  Observations began at ~ 8:04 UT, 3 minutes\nafter the burst.  A coaddition of our first five Kron R band images (3 x\n60 s, 2 x 120 s, mean epoch 8:14 UT), yields no new sources in the error\ncircle compared with the Digital Sky Survey.  Our limiting magnitude,\ncalculated with respect to several Guide Star Catalog sources in the\nfield, is approximately R > 21.0.  We note, however, the bright source\nmentioned by Bloom & Prochaska (GCN 3347) affects our sensitivity over a\nsignificant fraction of the error circle.\n\nFurther observations are planned.",
