Abstract
THE radio source identified with Cygnus X-3 was observed throughout the second great flare from 0100 UT on September 20, 1972, until 0800 UT on September 22, 1972, at 15.5 GHz using the 120-foot antenna of the Haystack Observatory in Westford, Massachusetts. In addition, two measurements were made at 22.235 GHz on September 21 and one was made at 8.105 GHz on September 22. The beginning of a third large flare is also present in our data.
