J. A. Kennea, D. N. Burrows (PSU) and N. Gehrels (GSFC) report on behalf
of the Swift/XRT Team:
Swift began a target of opportunity observation of the INTEGRAL discovered
burst GRB 050922A (GCN 4007) at 15:21:21 UT on September 22nd, 2005.
Analysis of ground processed XRT data reveals no point source inside the
INTEGRAL error circle. We estimate a 90% confidence level upper limit on
the X-ray flux from this burst of 3 x 10^-14 erg/s (0.5 - 10 keV).
