The analysis of photometric observations of the X-ray source Sco X-1 leads to the conclusion of the existence of a periodic component in the light variations of this source. For 1966–74, the results can be presented as

The photoelectric observations of some authors are shown in Figure 1, using the period. Figure 2 shows the mean light-curve of Sco X-1. The amplitude ΔB is about .
