Rotation period and sunspot activity - CESAR

The Rotation period of the Sun and the sunspot activity

The Sun as every star is an active and dynamic object. It rotates at a very high speed that we can calculate tracking the sunspots while rotating. Using the number of sunspots we can determine how active the Sun is at that moment and estimate where in the solar cycle we are.
