Three CMEs heading toward Earth, impact expected on February 13
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.
Proton flux rising after powerful farside eruption, S1 – Minor solar radiation storm
Proton flux started rapidly rising at 07:30 UTC on February 12, 2024, following what appears to be an eruption from the old Region 3575 – now traversing the farside of the Sun.
Strong M9.0 solar flare erupts from geoeffective Region 3576
A strong solar flare measuring M9.0 erupted at 23:07 UTC on February 10, 2024 from geoeffective Active Region 3576. The event started at 22:56 and ended at 23:14 UTC.
S2 – Moderate solar radiation storm following M6.7 solar flare
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.
M6.7 solar flare erupts from Region 3559, producing S2 – Moderate solar radiation storm
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, possible CME impact on December 27
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.
X2.8 solar flare produces Earth-directed CME, impact expected late December 16 to early December 17
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 CMEs impact Earth, sparking G3 – Strong geomagnetic storm
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.
M9.8 solar flare erupts from geoeffective Region 3500, Earth-directed CME likely
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.
Global SAR arc outbreak: Geomagnetic storm leads to rare SAR arc sightings across the globe
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.
