• Prolonged geomagnetic storming, isolated periods of G2 – Moderate levels

    Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS) for several days now. Enhanced solar wind parameters are expected to continue through October 1, with G3 – Strong geomagnetic storm levels possible today. G2 – Moderate…

  • Recurrent coronal hole sparks another round of geomagnetic storming

    High-speed solar wind from a recurrent coronal hole has sparked another round of geomagnetic storming on Earth. The solar wind environment is expected to remain elevated but steady through the rest of the UTC day before becoming further enhanced on September 28 and…

  • G1 – Minor geomagnetic storm conditions observed

    During the past 24 hours, solar wind parameters transitioned from near background conditions to an enhanced state, causing G1 – Minor geomagnetic storming on Earth. This was most likely caused by the onset of co-rotating interaction region (CIR) ahead of a negative…

  • Positive polarity CH HSS sparks geomagnetic storm

    Earth is under continued influence of a positive polarity coronal hole high speed stream (CH HSS), which is now causing geomagnetic storms at high latitudes. K-index of 5 (G1 – Minor geomagnetic storm) threshold was reached at 08:59 UTC on September 1, 2016. …

  • Spotless Sun heralds Solar Minimum after CME producing Region 2567 departs

    After Active Region 2567, the source of 7 M-class and numerous C-class solar flares between July 21 and 24, rotated away from the visible disk, our Earth facing Sun is again spotless. This is the third 'spotless Sun' since June 3, and although it is a…

  • 3 strong M-class solar flares erupt from Region 2567, CME produced

    Three strong solar flares erupted from Active Region 2567 early on July 23, 2016 – M5.0, M7.6, and M5.5. A Coronal Mass Ejection (CME) was produced during the third one, however, this region is not in a position to produce Earth-directed CMEs. The first flare…

  • Geomagnetic storm in progress

    A geomagnetic storm reaching G1 – Minor levels is currently in progress following the early arrival of July 17th Coronal Mass Ejection (CME). The interplanetary shockwave produced by the long duration C1 flare on July 17, initially expected to arrive early on July…
