According to Space Weather.com, Saturday, Feb 19th, 2011,
sunspot complexes, numbers 1161-1162 on Feb. 18th, are fast growing complexes producing a M6.6 Class solar flare. This is almost an X category flare,
and one of the strongest in years. These cause waves of ionization in the Earth’s upper atmosphere and disrupt many radio frequencies. However, some
signals can actually be boosted, while others diminished. I thought people would like to see a photo of what is causing these spectacular Auroras and
By comparing the two photos, you can match up the CME's with the sunspot activity.
This is a very descriptive and eloquent definition of the above provided by
"A solar flare is an explosion on the Sun that happens when energy stored in twisted magnetic fields (usually above sunspots) is suddenly released.
Flares produce a burst of radiation across the electromagnetic spectrum, from radio waves to x-rays and gamma-rays. Scientists classify solar flares
according to their x-ray brightness in the wavelength range 1 to 8 Angstroms. There are 3 categories: X-class flares are big; they are major events
that can trigger planet-wide radio blackouts and long-lasting radiation storms. M-class flares are medium-sized; they can cause brief radio blackouts
that affect Earth's polar regions. Minor radiation storms sometimes follow an M-class flare."
