GCN Circular 780
Paul Price, Tim Axelrod and Brian Schmidt (RSAA, ANU) report: "We have observed the error box of GRB000830 (Hurley et al., GCN #779) with 3 x 300s exposures with the 50-inch telescope at Mount Stromlo Observatory starting 31.73 August 2000 UT, i.e. 17.8 hr after the burst. Our R_MACHO and B_MACHO images cover all but the eastern-most half arcminute of the error box, and are slightly deeper than the Digital Sky Survey (DSS). We find no optical afterglow candidate as compared with the DSS to a 3-sigma limiting magnitude of R_MACHO ~ 20.5 mag." This message may be cited.
