		| Abstract: | 
		From 37-year-long photometry of the relativistic binary SS 433, we reveal secular changes in its light curve. Observations suggest that the expanding A-type component of this system passes to a dynamical mode of mass transfer filling and episodically overfilling the Roche lobe of the neutron star. |
