Abstract
We report on new X-ray and optical observations of PSR J2030+4415, a Gamma-ray Pulsar with an H\(\alpha\) bow shock. These data reveal the velocity structure of the bow shock apex and resolve unusual X-ray structure in its interior. In addition the system displays a very long, thin filament, extending at least \(5^\prime\) at \(\sim 130^\circ\) to the pulsar motion vector. Careful astrometry, compared with a short archival exposure, detects the pulsar proper motion at 85 mas yr\(^{-1}\). With the H\(\alpha\) velocity structure this allows us to estimate the distance as \(0.75\) kpc.
