• New large sunspot rotating Earthward on the eastern limb

    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

  • M-class flare events with Earth and Mars-directed CMEs

    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

  • An erupting cloud of plasma eclipsed by a dark magnetic filament

    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,

  • Sunspot 1363 subsiding, solar activity remains low

    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

  • Large solar prominence off northwest limb today

    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

  • Solar activity at start of December

    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
