CME hits Earth, sparking G2 – Moderate geomagnetic storm

A coronal mass ejection (CME) produced by a large filament eruption at 05:21 UTC on April 11, 2022 reached Earth around midnight UTC on April 14, sparking G2 – Moderate geomagnetic storm.

40 SpaceX Starlink satellites lost after geomagnetic storm hits Earth

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,…

Modest CME glancing blow from May 28 long-duration solar flare

Modest CME glancing blow from May 28 long-duration solar flare

A small part of coronal mass ejection (CME) produced by a long-duration C-class solar flare on May 28 hit Earth on June 2, 2021, barely disturbing Earth's magnetic field. Solar wind parameters are likely to become slightly enhanced due to the influence of a…

Geomagnetic storm watch in effect for May 18

Geomagnetic storm watch in effect for May 18

NOAA SWPC forecasters have issued a geomagnetic storm watch for May 18, 2021, after a pair of coronal mass ejections (CMEs) launched from the Sun on May 13 and 14. Enhanced solar wind parameters are expected on May 17 due to the influence of a negative polarity…
