Solar wind parameters in 24 hours to 00:30 UTC on April 17, 2024, continued to be enhanced by a passing coronal mass ejection (CME) which impacted Earth around 17:25 UTC on April 15 (launched from the Sun on April 12). Two more CMEs, produced on April 14 and 15, are expected to make a combined impact at around 00:00 UTC on April 18.
A G1 – Minor geomagnetic storm watch is in effect for April 14 and 15, 2024 due to two incoming coronal mass ejections (CMEs) — launched on April 11 and 12, combined with coronal hole high speed stream (CH HSS) influences.
Coronal mass ejection (CME) produced by the X1.1 solar flare at 01:33 UTC on March 23, 2024, is expected to impact Earth late March 24 or early March 25, producing G2 – Moderate to G3 – Strong geomagnetic storming.
A coronal mass ejection (CME) produced by C5.1 solar flare on February 28, 2024, impacted Earth at approximately 08:45 UTC on March 3, producing G2 – Moderate geomagnetic storming.
At least three coronal mass ejections (CMEs) are heading toward Earth. The impact is expected early on February 13 (UTC), producing G2 – Moderate or stronger geomagnetic storming.
Multiple coronal mass ejections (CMEs) produced on November 27 and 28, 2023, impacted Earth on December 1, sparking G3 – Strong geomagnetic storm. Similarly to the last G3 storm, on November 5, spectacular aurora sightings were reported from both hemispheres.
Multiple coronal mass ejections (CMEs) produced on November 27 and 28, 2023 are heading toward Earth, with impacts expected from late November 30 to mid-day UTC on December 1, 2023. As a result, a G3 – Strong Geomagnetic Storm Watch is in effect for December 1.
A G3 – Strong geomagnetic storming was observed on Sunday, November 5, 2023, as a result of the impact of two successive coronal mass ejections (CMEs) from the Sun. The storm produced auroras extending into the lower latitudes such as Colorado and Texas in the United States and Greece in Europe, which is unusual for such regions. Many people across both hemispheres have also recorded and captured rare red aurora.
The Coronal Mass Ejection (CME) that was launched on September 22, 2023, hit Earth’s magnetic field on September 24 at 20:43 UTC, sparking a moderate G2 – Moderate geomagnetic storm and rare red auroras. Initially detected in Canada where magnetometer readings spiked by 129 nT, the event later became visible across Europe, reaching as far south as France.
Two coronal mass ejections (CMEs) impacted Earth on September 18, 2023, producing G3 – Strong geomagnetic storming.
