   We propose an 80 ksec observation of PSR J0631+10, which has recently
   been discovered in the radio band during a follow-up study of
   unidentified sources detected by the Einstein IPC. Marginal detection
   of pulsations in the EGRET band have also been reported for PSR
   J0631+10. Combining the ROSAT archival data with this ASCA pointing, we
   intend to: 1) detect pulsations at the radio period; 2) search for an
   extended pulsar fed synchrotron nebula; 3) characterize the blackbody
   emission from the neutron star surface; and 4) determine a precise
   value of the interstellar absorption. The requested observation will
   provide important keys to the pulsar emission mechanism, the thermal
   history, and will provide a precise position for PSR J0630+10.
