|GCN Circular #2273: GRB 030528: Optical Observations|
N. Mirabal & J. P. Halpern (Columbia U.) report on behalf of the MDM Observatory GRB follow-up team: "We obtained I-band images on the MDM 1.3m for 1.5 hours on June 5.28, covering the positions of most of the Chandra X-ray sources listed by Butler et al. (GCN 2269) . We detect optical counterparts of three of the four sources within the revised SXC region reported by Villasenor et al. (GCN 2261) . The source CXOU J170400.3-223710, tentatively proposed as the GRB afterglow by Greiner et al. (GCN 2271), is not detected in any of our images to a preliminary limiting magnitude I > 21.5. Comparison with prior observations and deeper optical images of this location would be useful." This message may be cited.
