Abstract The microquasar SS 433 exhibits in H alpha intermittent flares,
Doppler shifted to both the red and the blue. The mean remembers the orbital
phase of the compact object. I show that the flares are not intermittent
sightings of an accretion disk; rather, plasma must be expelled through the L2
point, thus remembering the phase of the orbit as it invades the space beyond
the system. That space has been mapped with GRAVITY observations of a similar
flare, revealing a strong rotation component.
