• M3.5 solar flare took place around Sunspot 1263

    At 18:10 UTC Monday, a short duration M3.5 Solar Flare took place around Sunspot 1263. Because of its location, any explosions at this point may not be earth directed.Just when solar activity was slowing down, an M3.5 Solar Flare took place around Sunspot 1263

  • Behemoth sunspot 1263 has almost doubled in size

    Behemoth sunspot 1263 has almost doubled in size this weekend. A 28-hour movie from NASA's Solar Dynamics Observatory shows the spot developing a tail that has added some 50,000 km of length to the active region.This development may increase the likelihood of a stro

  • One of the strongest geomagnetic storms in years subsiding

    Earth's magnetic field is still reverberating from a CME strike on August 5th that sparked one of the strongest geomagnetic storms in years. Registering 8 on the 0 to 9 "K-index" scale of magnetic disturbances, the storm, at its maximum, sparked…

  • Geomagnetic storm still in progress but lingering

    A geomagnetic storm is in progress. It began on August 5th around 18:00 UT when a CME struck Earth's magnetic field. At its peak during the hours just after impact, the storm registered 8 on the 0 to 9 "K-index" scale of geomagnetic disturbances,…

  • 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
