• Geomagnetic storming reaching G2-Moderate levels in progress

    Coronal Mass Ejection (CME) produced by a long duration M6.5 solar flare on June 22 appears to have arrived at 13:00 UTC on June 24.Bt increased to 15nT and solar wind velocities increased to over 700 km/s at the time. Bz, however, remained largely positive and the over

  • Geomagnetic storming reaching G4-Severe levels in progress

    Three Coronal Mass Ejections (CMEs) produced on June 18, 19 and 21 have now all arrived at our planet and their combined effects caused G4-Strong geomagnetic storm on June 22, 2015. Two of the three CMEs were produced by Region 2371, one of the biggest regions of the cu

  • Partial-halo CME to deliver glancing blow on June 23

    Filament eruption in the SSE quadrant of the Sun produced a partial-halo Coronal Mass Ejection (CME) first observed in coronagraph imagery near 08:45 UTC on June 19 (above). WSA-Enlil model suggests a glancing blow early on June 23. Beta-Gamma-Delta classified…

  • Departing Region 2360 produces M1.3 solar flare

    Solar activity is again reaching moderate levels today with 'beta-gamma' classified Region 2360 being the most productive. This region, located near the western limb, produced an M1.3 solar flare at 07:29 UTC on June 13. The event started at 07:20 and ended at 0
