The light curve representing all available photometric data (B band) for QSO 3C 273 (1962-1987) is discussed. Fourier analysis of optical variability from 1962-1983 demonstrates the existence of a 307 day period for flares with amplitude of about 0.3 m (B). This period corresponds well with the frequency of ejections from the nucleus of the superluminal jet (about 1/yr), determined with the aid of high-resolution VLBI maps (1984-1985). This correspondence suggests a possible connection between optical flares and the ejection of superluminal jet components. It is noted that an earlier analogous correlation was found between 3C 345 and 3C 120. An optical flare with an amplitude of 0.6 m (B), which was recorded in 1983, corresponds with the 307-day period and also coincides with the 1.2 micron-3.3 mm flare, which had the same time scale, and was associated with the ejection of a superluminal component.
