CH HSS sparks G2 – Moderate geomagnetic storm

CH HSS sparks G2 – Moderate geomagnetic storm

Our planet is under the influence of a positive polarity Coronal Hole High Speed Stream (CH HSS) over the past 24 hours. Geomagnetic storms reaching G2 – Moderate levels were registered November 5. Solar wind parameters reflected the passage of a Solar Sector…

Positive polarity CH HSS sparks geomagnetic storming

Positive polarity CH HSS sparks geomagnetic storming

A G2 – Moderate geomagnetic storm watch has been issued for September 11, 2018 due to the onset of positive polarity coronal hole high speed stream. Solar wind parameters over the past 24 hours were descriptive of the passage of Co-rotating Interaction Region (CIR)…

G2 – Moderate geomagnetic storm conditions observed

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

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

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

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

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

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

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 -…
