摘要：
We have made multi-epoch observations of the unusual Xray binary star LSI +61degrees303 using the HALCA spacecraft in combination with a large array of ground radio telescopes. We present initial analysis of six observing epochs during a radio outburst. The images reveal an apparently stationary pattern of symmetric emission extending about 2 mas on either side of a central source. The central source is observed to expand at a rate of 0.25 mas/day. At the distance to LSI +61degrees303, this corresponds to similar to 860 km/s.
