Abstract
THE radio source, PSR 0833–45, a pulsar which is an obvious candidate for optical identification because of its similarity to the pulsar in the Crab Nebula1 and because of its relatively well established coordinates2, was observed on the nights of February 19–20 and 20–21, 1969, with the 60 inch telescope on Cerro Tololo. Slightly improved coordinates, kindly furnished in advance of publication by Dr A. E. Vaughan, isolate the field to an area roughly one photometer-aperture (15.8″) in size; the only star in this field is the one discussed in the current literature3,4.
