Supernova remnant (SNR) G63.7+1.1 is classified as a Crab-like in radio, but has not been detected in X-rays. With a 30 ks Chandra/ACIS observation, we discover a faint, extended X-ray nebula near the center of the SNR. Based on the spectral and morphological characteristics, we propose that the detected X-ray feature is emission from a pulsar wind nebula (PWN) in G63.7+1.1. The estimated X-ray luminosity is, however, remarkably low (Lx ˜ 6 x 1032 ergs/s in the 1-10 keV band). Follow-up X-ray observations with higher-sensitivity detectors are of considerable interest for the study of this unusually low-luminous PWN.
