Sunspot 1393 is growing rapidly, more than tripling in area since Friday. So far, however, the active region has not produced any strong flares. Solar activity remains low.Solar activity increased somewhat, with a solar flare detected around Sunspot 1386 off the
Sunspot 1384, currently located just behind the sun’s western limb, erupted today around 14:45 UTC. It registered as a long duration C2.4 flare and it appears to be connected to magnetic filaments snaking over the horizon to the Earthside of the sun. This event
Polar Light Center in Lofoten, Norway recorded today around 13:20 UTC, a wave of ionization that swept through the high atmosphere over Europe after sunspot AR 1389 unleashed another M2-class solar flare. NOAA/SWPC forecasters estimate a 40% chance of more M-flares
Emerging over the sun’s southeastern limb, sunspot AR1389 unleashed two M-class solar flares on Dec. 29th. A moderate M2.0 solar flare occur at 21:51 UTC Thursday evening and a moderate M1.9 Solar Flare this morning at 13:50 UTC. The blasts show that the
A new large sunspot is now rotating into view on the eastern limb. It just produced a minor C6.7 Solar Flare at 22:26 UTC Tuesday evening. Solar activity was moderate on Monday with one M-Class flare detected around Sunspot 1387. Numerous C-Class events were
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
