Weak and strong flaring has been observed at cm-wavelengths on Cygnus X-3. The weak flares seem to have different statistical properties to those of the strong flares. Previous observations have shown the ejection of radio emitting blobs at around 0.3c following major flares. However recent VLBA observations show apparent superluminal expansion and contraction during weak flaring.
