Pulsar NP 0532, near the center of the Crab Nebula, pulses optically with the same period as its radio emissions, according to W. John Cocke, Michael J. Disney and Donald J. Taylor of the Steward Observatory (International Astronomical Union Circular No. 2128, 1969). The University of Arizona group, using a 36‐inch reflector, discovered light flashing at the apparent radio period of 0.033095 sec from the region of a well known starlike object in the nebula.
