Further analysis of the spacecraft aspect data near the time of
GRB030528 indicates that an additional systematic correction to the
HETE SXC localization reported in GCN2256 (Atteia et al) is required.
This analysis uses the known position of Sco X-1, which was within
the SXC field-of-view at the time of GRB030528. We conclude that a
best estimate location for GRB030528 is:
RA (J2000) = 17h 03m 58s, Dec (J2000) = -22d 38m 00s
with an error radius of 2.5 arcminutes. This revised location is
displaced by 1.3 arcmin from the one reported in GCN2256.
