2013 was due to be year of the ‘solar maximum': The calm before the (solar) storm? Nasa reveals this amazing image of the sun – and issues warning that ‘something unexpected is happening there’


  • 2013 was due to be year of the ‘solar maximum’
  • As this picture shows, in fact the sun is incredibly calm – baffling experts

 

‘Something unexpected’ is happening on the Sun, Nasa has warned.

This year was supposed to be the year of ‘solar maximum,’ the peak of the 11-year sunspot cycle. 

But as this image reveals, solar activity is relatively low.

 

THE SOLAR CYCLE

Conventional wisdom holds that solar activity swings back and forth like a simple pendulum.

At one end of the cycle, there is a quiet time with few sunspots and flares.

At the other end, solar max brings high sunspot numbers and frequent solar storms.

It’s a regular rhythm that repeats every 11 years.

Reality is more complicated.

Astronomers have been counting sunspots for centuries, and they have seen that the solar cycle is not perfectly regular.
