The Ball-of-Light Particle Model predicts there would be a specific pattern for the timing of these balls-of-light as the core undergoes its specific decay pattern. This can be seen in the sun spot cycle.

The sunspot cycle -- defined by the number of observed sunspots -- declines for about 5.5 years and increases for about 5.5 years, creating an 11 year solar cycle. (This cycle can range between about 9 to 12.5 years.) Actually, the sun's magnetic polarity flips every 11 years so the sun actually goes through a 22 year cycle.
A record of the number of sunspots goes back to about year 1609-1610 -- this is when Galileo made his first telescope. We currently are in about the 28th recorded cycle.
If a large ball-of-light decays within the envelope, it can eject enveloping material along with its own decay-products, thus creating a solar eruption. The decay-products may include smaller balls-of-light.
"The dark core [of a sunspot] is stirred by movements of matter (hot rising structures with a diameter of about 200 kilometers), 'flashes', etc." (Page 38 of 1)
