Abstract
To study the rotation of sunspots, we selected the observational data for one group, namely for group which crossed the central meridian in October 4, 1974. This group was located in the southern hemisphere of the Sun (φ ≈ −60). It consisted of two large sunspots: preceding N-polarity spot and following S-polarity spot were separated by ∆L ≈ 90 in longitude. The magnetic field strength of both sunspots was approximately the same, i.e. about 2500G.
