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 [...]
Also we have flare of M 1.2 class, sunspot 1684.
Solar Cycle Update: Twin Peaks?
March 1, 2013: Something unexpected is happening on the sun. 2013 is supposed to be the year of Solar Max, the peak of the 11-year sunspot cycle. Yet 2013 has arrived and solar activity is relatively low. Sunspot numbers are well below their values in 2011, and strong solar flares have been infrequent for many months.
The quiet [...]
It WILL happen again.
On February 14 the sun erupted with the largest solar flare seen in four years—big enough to interfere with radio communications and GPS signals for airplanes on long-distance flights.
As solar storms go, the Valentine’s Day flare was actually modest. But the burst of activity is only the start of the upcoming solar maximum, due to peak in the next couple of years.
“The sun has an activity cycle, much like hurricane [...]
This still from a video taken by NASA’s Solar Dynamics Observatory shows the Aug. 8, 2011 solar flare as it appeared in the ultraviolet range of the light spectrum. The flare registered as an X6.9 class sun storm, the largest of the Solar Cycle 24.
An extremely powerful solar flare, the largest in over four years, rocked the sun early Tuesday (Aug. 9), but is unlikely [...]

The sun is waking up from a long quiet spell. Last week it sent out the strongest flare for four years â€“ and scientists are warning that earth should prepare for an intense electromagnetic storm that, in the worst case, could be a â€œglobal Katrinaâ€ costing the world economy $2,000bn.
Senior officials responsible for policy on solar storms â€“ also known as space weather â€“ in [...]
“The seven major benchmarks signaling the beginning of an Ice Age echo like the seven seals of the Apocalypse:
1. A short-lived warming cycle. Geological records show temporary warming spikes before the temperature drops and an Ice Age begins.
2. Increased precipitation. Heavy rains in the Southern Hemisphere. Heavier rains and snows in the Northern Hemisphere.
3. Partial melting of the Arctic icecap. The Arctic ocean becomes ice-free but [...]
