Trimming lead times on sunspot detection would allow for better forecasts of space weather—bursts of radiation and charged particles from the sun that can cause real problems on and around Earth.

In this paper, we have studied the radiation mechanism of the SVC for a unipolar sunspot-the combined radiation mechanism consisting of bremsstrahlung and cyclotron resonance radiation mechanism.

The sunspot spawned what's called a coronal mass ejection, sending tons of radiation and highly energized particles into space.
