We have analysed 3.9 ks of XRT data for GRB 230622A, from 383 s to 27.0
ks after the  BAT trigger. The data are entirely in Photon Counting
(PC) mode. Using 105 s of PC mode data and 1 UVOT image, we find an
enhanced XRT position (using the XRT-UVOT alignment and matching UVOT
field sources to the USNO-B1 catalogue): RA, Dec = 292.51735, -32.97036
which is equivalent to:

RA (J2000): 19h 30m 04.16s
Dec(J2000): -32d 58' 13.3"

with an uncertainty of 5.4 arcsec (radius, 90% confidence).

The results of the XRT-team automatic analysis are available at
