We used the time series radio flux data recorded at Sagamore Hill Solar Radio Observatory, Massachusetts. The rotation period estimated through statistical analysis shows continuous variation in its value. The variation in rotation period shows evidence of three components in the variation; first one is the ̴22-yr component, which may be linked to the solar magnetic field reversal (Hale’s) cycle, second one is the ̴11-yr component, obviously related to the Solar activity cycle and other one is a prominent random component. The cross-correlation between the annual average sunspot number and the coronal rotation period observed shows strong correlation with 22-yr Hale’s cycle and 11-yr solar cycle. |
