Timing measurements have been made of NP 0527 in order to examine its physical relationship with NP 0532. 18 months of timing data have been used to obtain an accurate frequency, rate of change of frequency and position. The calculated ‘slowdown age’ of the NP 0527 is 3.0 × 106 years which rules out an origin in the supernova explosion of 1054 A.D. The upper limit of its transverse velocity is 0.046c which is significantly less than the value necessary if it had a common origin with NP 0532.
