Strong positive polarity CH HSS sparks G2 – Moderate geomagnetic storm

Strong positive polarity CH HSS sparks G2 – Moderate geomagnetic storm

A strong positive polarity coronal hole high speed stream (CH HSS) sparked a G2 – Moderate geomagnetic storm on September 4, 2022. G1-Minor storms continued into September 5. An additional enhancement is possible by midday today due to the arrival of CME produced on September 2.

CME hits Earth sparking G2 – Moderate geomagnetic storm

A coronal mass ejection (CME) produced by the long-duration C2 solar flare on March 10/11, 2022, hit Earth early March 13, sparking G2 – Moderate geomagnetic storming. Disturbed conditions are expected to continue into March 14 and 15. The CME started around 18:00…

G2 – Moderate geomagnetic storm watch in effect

G2 – Moderate geomagnetic storm watch in effect

A G2 – Moderate geomagnetic storm watch is in effect for February 2, 2022, after a long-duration M1.1 solar flare produced an asymmetric, full-halo coronal mass ejection (CME) at 23:32 UTC on January 29. The CME is expected to reach Earth late February 1 or early…

CH HSS sparks G2 – Moderate geomagnetic storm

CH HSS sparks G2 – Moderate geomagnetic storm

Our planet entered a stream of fast-moving solar wind on January 18, 2022, sparking G2 – Moderate geomagnetic storm. A slightly enhanced solar wind environment is anticipated today as CH HSS effects taper, followed by a minor enhancement due to glancing blow effects…
