An M-Class flare with a double peak took place this afternoon at 20:30 UTC around active Sunspot 1387. The flare measured M2.3 and was captured by SDO in the image below. A long duration C5.7 Solar Flare was detected around Sunspot 1384 this morning (Dec 26) and
Sunspot 1387 produced another M-Class flare, this time peaking at M1.5. This latest solar flare took place at 02:27 UTC Monday morning and indicates the potential for bigger things to come.New sunspot 1387 erupted during the late hours of Christmas Day, producing an

Last night, NASA’s Solar Dynamics Observatory (SDO) observed an unusual event on the sun: An erupting cloud of plasma was eclipsed by a dark magnetic filament.The source of the explosion is a farside active region due to turn toward Earth in a few days. For now,
After three days of meteoric growth, sunspot AR1363 has reversed course and is beginning to decay. As its magnetic field relaxes, the active region poses a subsiding threat for strong flares. It’s not dead yet, though, as this snapshot shows: There is still a slim
Sunspot AR1363 is growing rapidly, more than doubling in size since Friday. A 48-hour movie from NASA’s SOlar Dynamic Observatory shows the expansion:The active region has a “beta-gamma” magnetic field that harbors energy for M-class solar flares. Because of
A magnetic filament rapidly erupted on the sun today. Between 10:30 and 11:30 UTC, observers in Europe watched tendrils of hot plasma rocket away from the sun’s NW limb. Debris from the explosion is not expected to hit Earth according to SpaceWeather. Solar
With no strong flares this week, the sun’s x-ray output has nearly flatlined. The solar activity is quiet and is expected to continue for another 24+ hours. NOAA forecasters estimate a mere 20% chance of M-class solar flares.C-Class flares continue to be detected
With no sunspots producing strong flares, the sun is officially quiet. But although the sun is officialy “quiet” multiple C-Class flares have been detected within the past 24 hours. C-Class flares continue to be detected around various locations on the visible solar
