GCN Circular 648
A. Dressler (Carnegie), A. Diercks, R. Gal, S. Yost, J. Bloom, and F. Harrison (Caltech) report: "We imaged the entire error circle of GRB000424 (Piro et al., GCN #644) with the COSMIC instrument on the Palomar 200" telescope at April 26.12 UT. Exposures consisted of 3x600s images in R-band with approximately 1.3" seeing FWHM. Visual comparison with a photographic f-band (approximate R-band) image from the DPOSS survey reveals no new objects to the detection limit of the plate (approximately R ~ 20.7)."
