Sunspot AR1416 Poses Threat for Earth-directed M-class flares

For the second day in a row, sunspot AR1416 has doubled in size. It has developed a beta-gamma magnetic field that harbors energy for M-class solar flares. Any such eruptions this weekend would be Earth directed as the sunspot turns to face our planet.

Solar Update: Active Sunspots Incoming

ACTIVE SUNSPOTS: Crackling with C-class solar flares, a pair of active sunspots is emerging over the sun’s northeastern limb. These sunspots have the potential for strong eruptions. Sunspot 1401 produced an M1-flare on Jan. 14th. Two days earlier, while it was still on the farside of the sun, sunspot 1402 produced a partially-eclipsed flare of uncertain magnitude that created waves of ionization in the atmosphere over Europe. NASA’s Solar Dynamics Observatory photographed the pair during the early hours of Jan. 15th.

NOAA forecasters estimate a 30% chance of more M-flares during the next 24 hours. Solar flare alerts: textvoice.
