Scientific paper

Observations of the pulsar with an interferometer of lobe spacing 0.055 arcsec were made in the frequency band 408-412 MHz. The rms image motion of the pulsar was found to be less than 0.0025 arcsec, a result consistent with thin-screen-scattering theory and with the assumed distance to the pulsar. Dynamic spectra with a frequency resolution of 10 kHz show fine structure in the distribution of pulse energy. Measurements made on features in the dynamic spectra are combined with the image motion limit to derive crude estimates of the pulsar's distance.
