Observations of the Crab Pulsar during an Occultation by the Solar Corona

Abstract

WE have measured the difference in time of arrival between individual pulses from NP 0532 (refs. 1 and 2) in frequency bands at 112, 142 and 170 MHz with the 300 foot telescope of the National Radio Astronomy Observatory. Observations were made between June 12 and June 23, 1969, when the pulsar had heliocentric angular distances in the range 1.5 to 8.7 degrees.
