Cygnus X-3 is one of the growing number of X-ray binaries known to have relativistic outflows. In Cyg X-3 these outflows occur during and after large flares in the radio which are always associated with activity in the hard and soft X-ray. On 1 April 2000 and for several days afterwards, Cygnus experienced several large (>10 Jy) flares. Here we present high resolution VLBA images of Cyg X-3 1, 2, 3, 5, 6, and 20 days after the peak of the first large flare. We will compare these images to previous VLBA observations in February 1997, which showed a curved one-sided relativistic jet.
