In this paper common regularities in flare positions have been studied in relation to spots as the extreme points of the magnetic field. The angular distribution diagrams of flares reveal that equatorial-western shifts of flares occurred during the I.G.Y. period (1957–58) in both hemispheres. This shift with some peculiarities is confirmed in the material of the 19th solar cycle, using the Solar Data bulletins, U.S.S.R., 1955–66. One result is that the western component of the shift does not change its sign and increases steadily during the cycle, while the equatorial component reverses sometimes and decreases steadily in amplitude to the end of the cycle.
