Major X2.8 solar flare erupts from Region 3514

Major X2.8 solar flare erupts from Region 3514

A powerful solar flare measuring X2.8 erupted from Active Region 3514 at 17:02 UTC on December 14, 2023. The event started at 16:47 and ended at 17:12 UTC. This is the strongest solar flare of the current Solar Cycle.

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.

On November 9, 2023, a low-level C-Class solar flare and a full halo coronal mass ejection (CME) were observed, starting shortly after 11:15 UTC. This solar activity, occurring near the Sun’s center disk, is anticipated to impact Earth by November 11, around 18:00 UTC, potentially triggering a G2 – Moderate geomagnetic storm. Concurrently, a minor polar cap absorption event is affecting shortwave radio transmissions in polar regions.

On November 5, 2023, observers across the globe were treated to a striking light show, courtesy of a G3 – Strong geomagnetic storm. This solar event was powerful enough to push the typically high-latitude auroras into lower latitudes, with sightings as far south as Texas and Arizona in the United States, as well as in European countries like Italy and Greece. Sightings were also reported in Australia and New Zealand.

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.
