We report on a new Chandra exposure of PSR J1809-2332, the recentlydiscovered pulsar powering the bright EGRET source 3EG J1809-2328. Byregistration of field X-ray sources in an archival exposure, we measure asignificant proper motion for the pulsar point source over an ~11 yearbaseline. The shift of 0.30+/-0.06" (at PA= 153.3+/-18.4) supports anassociation with proposed SNR parent G7.5-1.7. Spectral analysis of diffuseemission in the region also supports the interpretation as a hard wind nebulatrail pointing back toward the SNR.
