G3 – Strong geomagnetic storm watch

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.

40 SpaceX Starlink satellites lost after geomagnetic storm hits Earth

A geomagnetic storm affecting Earth on Friday, February 4, 2022, significantly impacted 40 of 49 SpaceX Starlink satellites launched to low Earth orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida on February 3. Preliminary analysis shows up…

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…

Series of CMEs impact Earth, sparking G3 – Strong geomagnetic storming

Series of CMEs impact Earth, sparking G3 – Strong geomagnetic storming

A coronal mass ejection (CME) produced by the long-duration M1.7 solar flare1 at 03:01 UTC on November 2, 2021, reached Earth at 19:57 UTC on November 3, sparking G3 – Strong geomagnetic storming. The CME overtook and merged with at least one, possibly two or more,…
