Abstract
THE sudden increase in radio flux observed1 from the direction of Cygnus X-3 on September 22–23, 1972, occurred just as we began a four-antenna very-long-baseline interferometry experiment that involved a pair of radio telescopes in Green Bank, West Virginia, and another pair in Massachusetts (Table 1). We were able to take advantage of this opportunity to observe Cygnus X-3 interferometrically on September 24 and report here the negative results of these observations.
