dc.descriptionWe report on VLBA astrometry and CXO imaging of PSR J0538+2817 in the supernova remnant S147. We measure a parallax distance of $1.47^{+0.42}_{-0.27}$kpc along with a high-precision proper motion, giving a transverse velocity $V_\perp=400^{+114}_{-73}$km/s. A small extended wind nebula is detected around the pulsar; the symmetry axis of this structure suggests that the spin axis lies $12\arcdeg\pm4\arcdeg$ from the velocity vector (2-D), but the emission is too faint for robust model independent statements. The neutron star is hot, consistent with the young ~40kyr kinematic age. The pulsar progenitor is likely a runaway from a nearby cluster, with NGC 1960 (M36) a leading candidate.
