• Earth hit by slow-moving CME, triggers G1-Minor geomagnetic storm; second CME on the way

    ByTeo Blašković

    A slow-moving coronal mass ejection (CME) that left the sun on February 11, 2023, reached our planet today, causing G1 – Minor geomagnetic storming. A partial halo CME, possibly triggered by a filament eruption near Region 3220 on February 14 is forecast to impact Earth this week, which could result in disruptions to communication networks, power grids, and satellites. The timing and extent of the impact are still being analyzed.

  • G3 – Strong geomagnetic storm watch

    A series of coronal mass ejections (CMEs) produced on August 14 and 15, 2022 are expected to couple with a recurrent, negative polarity coronal hole high speed stream (CH HSS), sparking G1 – Minor to G3 – Strong geomagnetic storming through August 19.

  • CME impacts Earth, sparks G2 – Moderate geomagnetic storm

    Coronal mass ejection (CME) produced by M1.6 solar flare at 06:40 UTC on October 9, 2021, reached DSCOVR spacecraft at 01:48 UTC and Earth at 02:30 UTC on October 12, 2021. The impact sparked a G2 – Moderate geomagnetic storm. In 24 hours to 00:30 UTC on October 12,…

  • Modest CME glancing blow from May 28 long-duration solar flare

    ByTeo Blašković

    A small part of coronal mass ejection (CME) produced by a long-duration C-class solar flare on May 28 hit Earth on June 2, 2021, barely disturbing Earth's magnetic field. Solar wind parameters are likely to become slightly enhanced due to the influence of a…
