Mulchaey (Carnegie\nObservatories) report on behalf of a larger collaboration:\n\n\"We imaged the error box of GRB000630 (Hurley, GCN 736) with the Cosmic\ninstrument of the Palomar 200\". Exposures consisted of R-band 2X450\nseconds on July 1.29 UT. The seeing was approximately 0.9\". We detect an\nobject at the position of the optical afterglow reported by Jensen et al.\n(GCN 747). We calibrated the field by PSF photometry, comparing 18 field\nstars with the photometry of Henden et al. (GCN 746), and obtain a\nmagnitude of the optical afterglow as R = 23.47 +- 0.13.\"\n\nThis message may be cited.",
