An impressive sunspot on the east side of the sun, could produce eruptions and storms in the coming days, possibly towards Earth. The large region of the sun contains more than a dozen dark cores. The largest sunspot is big enough to swallow two planet Earths and has the potential to disrupt transmission and reception of radio signals.
The sunspot has a "beta-gamma" magnetic field that harbors energy for strong eruptions. NOAA forecasters estimate a 75% for M-flares and a 30% for X-flares. The effect of any flares will be mitigated by the fact that the sunspot is not yet directly facing Earth. However, even an off-center blast from the large sunspot could produce radio blackouts and geomagnetic activity.
