Sun produces no sunspots for longer than normal
The Sun goes through 11-year activity cycles. Solar activity entails solar eruptions, solar flares and sunspots. The most intense activity occurs during the middle of the cycle, while the least intense activity occurs at the beginning and end of a cycle.
With the previous cycle currently ending and a new one beginning the Sun is going through a period of inactivity. While this is normal, this period has lasted longer than usual. The Sun has been relatively inactive for the last 2 years and scientists do not know why.
