P. Price, T. Axelrod and B. Schmidt (Research School of Astronomy and
Astrophysics, Australian National University) report:
"We have imaged the error box of GRB000911 (Hurley et. al., GCN #791) with
the MSO 50-inch telescope + MACHO camera. Our 4 x 300s exposures,
starting at September 12.73 UT (approximately 1.4 days after the burst)
cover the entire error box. The 3-sigma limiting magnitude of the combined
red image is R ~ 20.7 mags (based on the USNO-A2.0 catalogue). We do not
detect any optical afterglow candidate on comparison with the DPOSS
(Djorgovski et. al., 1999)."
