We have redetermined the parallax and proper motion of the nearby isolated neutron star RX J185635−3754. We used eight observations with the high-resolution camera of the HST/ACS taken from 2002 through 2004. We performed the astrometric fitting using five independent methods, all of which yielded consistent results. The mean estimate of the parallax, 8.16+0.9−0.8 mas (1σ), corresponds to a distance of 123+11−15 pc, in good agreement with our earlier published determination.
