Abstract: The amplitude and sinusoid-like shape of the optical variability of the light curve of PG 1302-102 is best fitted by relativistic Doppler boosting of emission from a compact, steadily accreting, unequal-mass binary, which is consistent with archival ultraviolet data, and suggests the existence of a binary black hole in the relativistic regime.
