Aims.We present a new optical observation of the X-ray dim isolated neutron star RX J1605.3+3249, performed in 2005 with the Wide Field Channel (WFC) of the Advanced Camera for Surveys (ACS) on board Hubble Space Telescope, aimed at measuring the neutron star proper motion.
Methods.We have compared the target position with the one measured in a previous HST image of the field obtained in 2001.
Results.We infer a proper motion of ± 3.1 mas/yr, corresponding to a star velocity
km s-1 at 100 pc distance. Our measurement refines the result
recently reported by Motch et al. (2005, A&A, 429, 257), and confirms the optical
source as the counterpart of the neutron star.
