• M1.4 Earth-directed solar flare took place

    Magnetic fields above sunspot 1261 erupted this morning at 0648 UT, producing an M1-class solar flare. The blast also hurled a bright coronal mass ejection toward Earth. This movie from the STEREO-Ahead spacecraft shows the cloud racing away from the sun at almost

  • Geomagnetic storm in progress!

    Geomagnetic K-index of 5 alert is issued by Space Weather Prediction Center. Kp-indices of 5 or greater indicate storm-level geomagnetic activity. Geomagnetic storms have been associated with satellite surface charging and increased atmospheric drag.Speed of solar

  • A strong M9.3 solar flare took place

    Sunspot AR1261 unleashed a brief but strong M9-class solar flare on July 30th at 0209 UT. NASA’s Solar Dynamics Observatory recorded the flare’s extreme ultraviolet flash:Because of its brevity, the eruption probably did not hurl a substantial CME toward Earth,

  • Sun harbors energy for powerful X-class solar flares

    Sunspot 1260 has developed a delta-class magnetic field that harbors energy for powerful X-class solar flares. Such an eruption today would be Earth-directed as the sunspot turns to face our planet.Sunspot 1260 is leading a parade of big sunspots across the solar

  • M-Class solar flare in effect

  • Solar activity is picking up again

    After more than a week of quiet, solar activity is picking up. NASA’s Solar Dynamics Observatory is monitoring two big sunspot groups now emerging over the sun’s eastern limb. Click on the image to view a 40-hour movie.The leading sunspot group, AR1260, is crackling
