Study of Variations in Solar Differential Rotation Based on Compact Magnetic Features and Hydrogen Hα Filaments

  • Published:
Astrophysics Aims and scope

Abstract

Data on compact magnetic features and hydrogen Hα filaments during solar activity cycles 20 and 21 are used to study variations in the solar differential rotation. The difference in the differential rotation rates of the compact magnetic features and hydrogen Hα filaments is greatest between the 20-30° and 30-40° latitude zones in both solar hemispheres. The rotation rates of the compact magnetic featuresat all latitudes are higher than those of the hydrogen Hα filaments and the difference between them increases with latitude.
