Sunspots, the source of solar flares are produced by plasma vortexes, or
more apply plasma hurricanes that actually disrupt the convection of energy
carrying photons from the sun's core deeper in the sun.

Sunspots are temporary phenomena on the surface of the Photosphere that
appear as dark spots compared to the surrounding regions. They are caused
by intense magnetic activity, which inhibits convection, forming areas of
lower surface temperatures. If a Sunspot were isolated from its surrounding
Photosphere, it would be brighter than an electric arc. Sunspots expand and
contract as they move across the surface of the sun. They can be as large
as 50,000 miles in diameter making the larger ones visible from Earth.

In more detail, it is now believed that the twisting magnetic action in the
plasma Convection Zone just below the sun's surface causes sunspots to
form, flares, etc. to form, and the sun's magnetic field to reverse itself
every 22 years. (The earth's magnetic field also reverses itself, but only
about once every million years.

If the sunspot was a significant source of nuclear activity at the surface
of the sun, the spots would be brighter than the surrounding surface area.

The case for nuclear production inside the vortex during its formation
might be carried by the fact that neutrinos begin to increase some 36 hours
before the solar flare erupts.

Purdue nuclear engineer Jere Jenkins, while measuring the decay rate of
manganese-54, a short-lived isotope used in medical diagnostics, noticed
that the rate dropped slightly during the flare, a decrease that started
about a day and a half before the flare.

The assumption is that the increase in neutrino production and associated
nuclear activity decreases the rate of radioactive decay.

Flares are formed when intense magnetic fields from below the sun's surface
link up with magnetic fields in the outer Corona in a process called
"Magnetic Reconnection". Flares are powered by the sudden release of
magnetic energy stored in the sun's Corona. The same energy release may
also produce a Coronal Mass Ejection (CME), but not always. And, sometimes
CMEs form without Flares. The connection between Flares and CMEs is not
well understood.
Magnetic Reconnection is a physical process in highly conductive plasmas
where magnetic fields clash, re-configure themselves into a lower energy
level, and the excess magnetic energy is then converted into kinetic and
thermal energy. Big Flares are equivalent to billions of megatons of TNT
exploding within a few seconds. A big flare can produce one sixth of the
total energy output of the sum localized at a small spot on the sun.

Billions of tons of electrons, protons, and other particles that are
accelerated by Magnetic Reconnection in a Flare approach the speed of
light. It is still not possible to predict when a CME or Flare will erupt
because the trigger mechanism isn't known.

It might be that the flare and the CME occur at a later stage of the
magnetic field formation process. Nuclear reactions caused by the magnetic
mechanisms inside the sunspot gradually increase over days before a flare
occurs.
Strangely, the video from Purdue referenced below shows that there is a
precise relationship between the total production of EMF in the sun and the
radioactive decay rate seen on earth at about 26 minutes into the video.
IMHO, this is an alternative causation posit to the neutrino causation
posit.

Whatever it is, this effect goes as the inverse square of the distance from
the sun. When the experiments at the earthbound source of neutrinos are
conclusively tested at a nuclear reactor, and no effect on isotope decay
rates are bot seen, then EMF production from the sun will remain as the
probable source of this effect. And this effect must be a magnetically
based LENR effect if the reaction is happening locally here on earth.
