behalf of a larger collaboration:
"Beginning on September 14.36 we re-observed the IPN error box of
GRB000911 (GCN #791) with the VLA at 8.46 GHz. We find one new source
which is not cataloged in the NRAO VLA Sky Survey (NVSS), with a flux
density of approximately 300 microJy, at RA=02:18:34.362 Dec=+07:44:27.65,
with a conservative error of 0.6 arcsec in both. The flux at this
position appears to have increased by approximately 2-sigma since our
previous observation on September 13.49 (GCN #794).
We have also re-examined the image from the Mount Stromlo Observatory
50-inch telescope of September 12.73 UT (GCN #793) at the position of the
radio candidate. We detect a faint source with R ~ 20.6. We note that
there are no sources at this position on the DPOSS images (Djorgovski et.
al., 1999). Typical limiting magnitudes are B_J ~ 22.5, R_F ~ 20.8, and
I_N ~ 19.5.
Further observations at the VLA are planned."
