• G2 – Moderate geomagnetic storm conditions observed

    G2 – Moderate geomagnetic conditions were observed on May 6, 2018 in response to the influence of a negative polarity coronal hole high speed solar wind stream. G1 – Minor geomagnetic storm conditions were first observed at 17:59 UTC on May 5, followed by G2 at…

  • G2 – Moderate geomagnetic storm in progress

    A G2 – Moderate geomagnetic storm threshold was reached at 08:25 UTC on April 20, 2018 and G2 warning is in now in effect until 12:00 UTC. An interplanetary shock wave hit Earth's magnetic field around 23:50 UTC on April 19, Dr. Tony Phillips of SpaceWeather.com…

  • Negative polarity CH HSS sparks G2 – Moderate geomagnetic storm

    A persistent negative polarity coronal hole high speed stream (CH HSS) sparked G2 – Moderate geomagnetic storm on March 18, 2018. A gradual return to background levels is expected on March 19 as CH HSS influence subsides. However, enhanced solar wind parameters are…

  • Geomagnetic storms reaching G2 – Moderate levels, spotless Sun

    Earth is again under the influence of a recurrent, positive polarity, northern extension Coronal Hole High Speed Stream (CH HSS). G1 – Minor geomagnetic storm level threshold was reached at 11:55 UTC, followed by G2 – Moderate at 19:21 UTC. Over the past 24 hours,…

  • Geomagnetic storming reaches G2 – Moderate levels

    Our planet is under the influence of coronal hole high speed stream (CH HSS) for the third day in a row. The geomagnetic field was unstable, with isolated periods of G1 – Minor storm levels during the past two days and then increased to G2 – Moderate levels at 14:59…

  • G3 – Strong geomagnetic storm levels reached

    A recurrent, polar-connected, positive-polarity coronal hole is affecting our planet since September 27. G1 – Minor geomagnetic storm levels were reached at 08:48 UTC on September 27, followed by G2 – Moderate levels at 20:24 UTC and then increased to G3 – Strong…

  • CH HSS sparks G2 – Moderate geomagnetic storming

    A stream of high-speed solar wind coming from a recurrent, polar-connected, positive-polarity coronal hole is affecting our planet today and causing geomagnetic storming. G1 – Minor geomagnetic storm levels were reached at 08:48 UTC and increased to G2 – Moderate…

  • G2 – Moderate geomagnetic storm in progress

    Our planet is under the influence of a positive polarity coronal hole high speed stream (CH HSS) which is causing isolated periods of G2 – Moderate geomagnetic storming. Geomagnetic K-index of 5 (G1 – Minor) geomagnetic storm threshold was reached at 15:43 UTC. G2 -…

  • Direct CME hit expected, G3 Strong geomagnetic storm watch issued

    An asymmetric full halo Coronal Mass Ejection (CME) produced by the M5.5 solar flare at 20:33 UTC on September 4, 2017 is traveling toward Earth and is expected to arrive late on September 6. G3 – Strong geomagnetic storm watch is in effect for September 6 and 7….
