• Solar wind stream buffeting Earth's magnetic field

    During last 24 hours solar wind stream buffeted Earth's magnetic field causing geomagnetic storms around the poles. Geomagnetic conditions were short lived reaching G1 – Minor geomagnetic storm levels (Kp=5). At those levels weak power

  • 2013 July solar prominences

    This movie provides an overview of nine great solar prominences that were visible in July 2013.

  • Large solar prominence on the northwest limb

    A large prominence lifted off the northwest limb on July 21, 2013 and generated a Coronal Mass Ejection (CME), directed to the north and away from Earth. 

     

    STEREO Ahead and STEREO Behind COR2 images show the prominence flaring on July 22, 2013

  • G1 geomagnetic storm in progress (July 15, 2013)

    A minor geomagnetic storm is currently in progress due to slow-moving CME that erupted on July 9, 2013 and swept past Earth on July 13, 2013. The Bz component of the interplanetary magnetic field (IMF) tipped sharply south late on July 14,

  • Incoming CME to spark geomagnetic storming on July 13, 2013

    We saw increased geomagnetic activity for past two days as Kp index reached K=5, G1 geomagnetic storming level, on July 10. A minor CME hit Earth's magnetic field on July 9, 2013 at approximately 20:30 UTC and peaked during the early hours of

  • M1.5 solar flare erupted from Sun's eastern limb

    A moderate solar flare reaching M1.5, at its peak time, erupted on July 3, 2013. The event started at 07:00, peaked at 07:08 and ended at 07:18 UTC. The source of the event was probably Beta classified Region 1785 located on the Sun's eastern limb or the

  • Strong G3 geomagnetic storm in progress (June 29, 2013)

    As Earth passes through a new coronal hole high speed stream, backed by unidentified CME shock, a prolonged interval of south-pointing magnetism (southward Bz) is having a strong impact on Earth's geomagnetic field. On June 29, 2013 Planetary K-index

  • Weak CME impact and filament channel eruption on the Sun

    An interplanetary shock wave hit our planet's geomagnetic field on June 27, 2013 at approximately 14:20 UTC. Geomagnetic Sudden Impulse was registered at 14:40 UTC. The impact was relatively weak and has not caused a geomagnetic storming so far.

  • SDO – Comparing solar activity levels

    SDO released one-month videos of comparin the Sun's activity from periods about 2.5 years apart, with remarkable increase in solar activity seen. The video from October, 2010  sets it next to video from May, 2013 in the SDO's 171 Angstrom wavelength
