The Sun has a heartbeat. The number of Sunspots varies. However, it is not a random
variation; it shows an 11 year periodicity.
Data for 11 year solar cycle.
The reason for this 11 year heartbeat is not understood. We are heading into "Solar Max"
next year.
Projections for next year's sunspots.
We can expect an increase in the number of Auroras (Northern Lights) this year and
next.
