ACTIVE SUNSPOTS: Crackling with C-class solar flares, a pair of active sunspots is emerging over the sun’s northeastern limb. NASA’s Solar Dynamics Observatory photographed the pair during the early hours of Jan. 15th:

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.

NOAA forecasters estimate a 30% chance of more M-flares during the next 24 hours
