Following the M6.7 solar flare from Active Region 3559 on January 29, 2024, enhanced proton levels were recorded, with the greater than 10 MeV reaching the S2 – Moderate threshold and greater than 100 MeV peaking at 0.67 pfu.
A moderately strong solar flare measuring M6.7 erupted from Active Region 3559 (beta-gamma) at 04:38 UTC on January 29, 2024. The event started at 03:54 and ended at 05:15 UTC.
Multiple M-class solar flares and CMEs were recorded on December 24, 2023. Forecasts indicate potential geomagnetic disturbances with a grazing blow expected late on December 27, 2023.
A major solar event occurred on December 14, 2023, when a powerful solar flare measuring X2.8 erupted from Active Region 3514. This event, which started at 16:47 and ended at 17:12 UTC, is the strongest solar flare since September 10, 2017, and 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.
A very strong solar flare measuring M9.8 erupted from Active Region 3500 at 19:50 UTC on November 28, 2023. The event started at 19:35 UTC and ended at 20:09 UTC.
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.
A large filament eruption centered near N30W30 was observed in H-alpha imagery around 05:00 UTC on November 3, 2023.
NOAA’s Space Weather Prediction Center (SWPC) has revised its forecast for Solar Cycle 25, predicting a quicker and more intense peak in solar activity between January and October 2024. The updated prediction challenges the previous expert panel’s forecast from 2019.
