• Strong M9.9 solar flare erupted from AR 1936

    At 18:52 UTC today (January 1, 2014) strong solar flare measuring M9.9 erupted from Region 1936. R2 Moderate solar radiation storm was reported: area of impact centered primarily on sub-solar point on the sunlit side of Earth, limited blackout of HF

  • Moderate M1.2 solar flare erupted around AR 1909

    Moderate solar flare measuring M1.2 erupted today from around AR 1909. The event started at 07:17, peaked at 07:29 and ended at 07:49 UTC. Region 1909 (S17W50, Dso/beta) is decreasing in size but maintains some magnetic complexity.

  • Second moderate solar flare around western limb – M1.0

    After an impulsive M1.1 solar flare at 02:23 UTC today, a second M-class solar flare erupted from AR 1904 located around the west limb. The latest event peaked at 12:27 UTC as M1.0 solar flare. No Earth directed CMEs were observed.

  • Impulsive M1.1 flare erupted around western limb

    An impulsive M1.1 solar flare was detected around departing Sunspot 1899 at 02:32 UTC on November 23, 2013. The source was actually a newly numbered Region 1904 (N12W60, Dai/beta-gamma). This region appeared to have enough of a separation in SDO HMI/Magnetogram imagery

  • M1.2 solar flare erupted from Sunspot 1893 behind the western limb

    A moderate M1.2 solar flare was detected around sunspot 1893 at 11:11 UTC on November 21, 2013. This active region is now located behind the west limb, so any subsequent coronal mass ejections (CMEs) would be too far west to impact Earth. This same region is
