• 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

  • Impulsive M2.9 solar flare erupted from eastern limb

    Moderate M2.9 solar flare erupted at 20:56 UTC on June 23, 2013. The event started at 20:48 UTC and ended at 20:59 UTC. The flare originated from Active Region 1778 that just emerged at eastern limb.

    M2.9 solar flare recorded by SDO's EVE and GOES X-Ray

  • Solar wind stream buffers Earth magnetic field

    Earth is currently inside a solar wind stream flowing in from the massive coronal hole on the Sun's northern hemisphere. Elevated solar wind speed (above 600 km/s) combined with a south tilting Bz component of Interplanetary magnetic field (IMF) is responsible

  • Moderate solar flare measuring M2.9 erupted from Region 1777

    A moderate solar flare registered as M2.9, at the peak time, erupted from Region 1777 on June 21, 2013. The event started at 02:30 and peaked at 03:14 UTC. A Type IV Radio Emission was associated with the event. Type IV emissions occur in association with

  • Moderate solar flare reaching M5.9 erupted from AR 1762

    Moderate M5.9 solar flare erupted from decaying Actve Region 1762 at 22:49 UTC on June 7, 2013. The event started at 22:11 UTC and ended at 23:04 UTC. This eruption hurled Coronal Mass Ejection (CME) into space, but considering the location of eruption, the plasma
