Abstract
For solar cycles 20 and 21 the latitudinal variations of the solar rotation rates are found using data of the Hα filaments and the long-lived magnetic features of negative and positive polarities. Analysis of the data showed that: (a) there is N-S asymmetry in the equatorial rotation of the Hα filaments and the long-lived magnetic features; (b) for both solar cycles the long-lived magnetic features of both polarities have similar behavior; (c) in the solar cycle 20 the long-lived magnetic features of both polarities vary in phase to each other but show some difference during cycle 21. For the long-lived magnetic features of positive polarity the confidence level is lower than for those of negative one.
