✦ Synopsis

Based on observational data on chromosphere filaments, certain characteristics of solar differential rotation during solar activity cycle No. 21 are determined at Abastumani Astrophysical Observatory.

In the northern hemisphere of the Sun, propagation of a quasi-N-annual impulse of the rotation residual from high latitudes to the equator is found in 1979-1981. It is supposed that this phenomenon might be related to the polarity reversal in the northern hemisphere of the Sun in 1981.0.
