We present preliminary results from an ASCA observation of PSR J1119-6127, an isolated radio pulsar with period P = 0.4 s and period derivative ˙ {P} = 4 x 10-12, the largest known of any radio pulsar. This pulsar, recently discovered in an ongoing survey of the Galactic plane at the 64-m Parkes telescope, has an extremely young characteristic age τ c = 1600 yr and large spin-down luminosity ˙ {E} = 2 x 1036 ergs s-1, making it a likely candidate for high-energy emission. In fact, X-ray emission is detected from the position of the radio pulsar and from an region 14' in extent, centered roughly on the pulsar and spatially coincident with a ring-like shell of radio emission. We suggest that this extended emission is a previously unidentified supernova remnant associated with pulsar PSR J1119-6217. M. J. P. is supported in part by NASA under Contract NASA-37716. V. M. K. is supported in part by the NASA Long Term Space Astrophysics program under grant NAGS-8063.
