The next maximum in the activity cycle of the Sun will be in 2011, although scientists consider that it will not be of great intensity. The prediction is made from the data of the last cycle. Theoretical models of the Sun have also been developed, but so far they have not been successful in predicting the activity. Now, scientists from China and India have improved their theoretical models and the results coincide with the prediction made from the latest data. Therefore, they are convinced that the 2011 maximum will not be violent.
