• Major solar flare reaching X2.2 erupted from southeastern limb

    An impulsive solar flare reaching X2.2 at its peak time erupted on June 10, 2014, generating R3 (Strong) radio blackout. The event started at 11:36, peaked at 11:42 and ended at 11:44 UTC. Source was Active Region 2087 located on the southeastern limb.A large Coron

  • The best observed X-class flare

    On March 29, 2014 the sun released an X-class flare. It was observed by NASA's Interface Region Imaging Spectrograph, or IRIS; NASA's Solar Dynamics Observatory, or SDO; NASA's Reuven Ramaty High Energy Solar Spectroscopic Imager, or RHESSI; the Japanese Aer

  • Major solar flare measuring X1.3 erupted behind the west limb

    Major solar flare measuring X1.3 erupted on April 25, 2014 from Region 2035 located behind the western limb. The event started at 00:17, peaked at 00:27, and ended at 00:38 UTC. Because of the location of this region CME was not Earth directed.R3 (strong) Radio Blac

  • Major solar flare measuring X1.0 erupted from Region 2017

    Major solar flare measuring X1.0 erupted from Region 2017 on March 29, 2014. This event started on 17:35, peaked at 17:48 and ended at 17:54 UTC. Area of impact consists of large portions of the sunlit side of Earth, strongest at the sub-solar point. Wide

  • Near X-class solar flare and geomagnetic storm – M9.3

    Near X-class solar flare reaching M9.3 erupted from departing Sunspot 1996 on March 12, 2013 at 22:34 UTC.

    This decaying sunspot is located near eastern limb and generated CME was not geoeffective, however, it produced a R2 (Moderate) Solar Flare Radio Blackout

  • Powerful X4.9 solar flare erupted from Sunspot 1990

    Newly numbered Active Region 1990 produced powerful X4.9 solar flare at 00:49 UTC on February 25, 2014, making it the third largest X-flare event of the current solar cycle. This decaying sunspot is in fact old returning region previously numbered as AR 1967. This is

  • Solar flare reaching X1.0 erupted from southwest limb

    Solar flare peaking as X1.04 erupted from Sun's southwest limb at 10:26 UTC on November 19, 2013. This event was observed around 'beta-delta' classified AR 1893. 

    A Type II Radio Emission was registered at 10:24

  • Major X1.1 solar flare erupted from Earth facing AR 1890

    Active Region 1890, located almost at the center of the disk, erupted with impulsive X1.1 solar flare at 05:14 UTC on November 10, 2013. A very bright Coronal Mass Ejection (CME) has been observed and the bulk mass seems to be heading well south of the
