CME impact sparks G2 – Moderate geomagnetic storm
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.
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.
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.
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.
A coronal mass ejection (CME) produced by filament eruption on August 2, 2023, combined with a smaller CME produced on August 1 and reached our planet at 02:53 UTC on August 5.
Co-rotating interaction region (CIR) followed by negative polarity coronal hole high speed stream (CH HSS) produced G1 – Minor and G2 – Moderate geomagnetic storming on Earth on June 15 and 16, 2023.
A full-halo coronal mass ejection (CME) produced by an Earth-facing filament eruption on April 21, 2023, impacted Earth at 17:37 UTC on April 23. The impact sparked G4 – Severe geomagnetic storm and produced vivid aurora worldwide.
A G4 – Severe geomagnetic storm on March 24, 2023, caused red auroras to appear over Florida and other low-latitude areas, marking the first such sighting over Florida in nearly 20 years. Numerous unusual phenomena were observed during this geomagnetic storm, including “aurora dunes” over Alberta, Canada.
