First e-VLBI observations of Cygnus X-3
We report the results of the first two 5 GHz electronic very-long-baseline interferometry (e-VLBI) observations of the X-ray binary Cygnus X-3 using the European VLBI Network. Two successful observing sessions were held, on 2006 April 20, when the system was in a quasi-quiescent state several weeks after a major flare, and on 2006 May 18, a few days after another flare. At the first epoch we detected faint emission probably associated with a fading
