Two Bright New Quasi-stellar Radio Sources

Abstract

A 2,695 MHz survey of radio sources in a narrow strip of declination has recently been completed with the Jodrell Bank Mk II radio telescope (full details will be published later). Accurate positions for all the 74 sources have been measured with the RRE Malvern 2,695 MHz interferometer. Using these positions and a transparent overlay technique of identification the relative positions of radio and optical objects were located on the National Geographic‐Palomar Sky Survey prints with an r.m.s. error of 4 arc s. In the 24 h of right ascension covered by the survey, twenty-three identifications with stellar objects have been made; among these are two remarkably bright (14.5 magnitude) objects, separated by less than two degrees in the sky, which may be worthy of special attention. Finding charts for these two objects are shown in Fig. 1.
