Abstract

Position measurements of the Crab nebula pulsar NPO527 made with a split-beam antenna yield the position (1950) α=05h26m10S±40S, δ=22°0±30. Thus NPO527 lies 1.2° from the pulsar NPO532, which is located at the nebula. The proximity and similar dispersion of these two pulsars suggest that they may have had a common origin in the supernova explosion of A.D. 1054 and hence that NPO527 is moving with a velocity of 0.15c, a hypothesis which could be tested directly by proper motion measurements.
