We used the integrated radio flux recorded daily at 245, 410, 606, 1415, 2695, 4995, 8800 and 15400 MHz frequencies through radio telescopes situated at Segamore Hill Solar Radio Observatory, Massachusetts. The radio flux radiation at different frequencies originates from different layers of the solar upper atmosphere. The data available from 1966 to 2010 was analysed to give information about the variation in equatorial solar rotation of corona and chromospheres at different altitudes. The altitudinal and temporal variation in solar rotation period has been study for the whole observed period. A systematic interrelation has also been seen in rotational variation with altitude and also with the phases of solar cycle. |
