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.
