G3 – Strong geomagnetic storm in progress
A coronal mass ejection (CME) produced by a long-duration M8.2 solar flare at 07:09 UTC on August 1, 2024, reached Earth early on August 4, causing G3 – Strong geomagnetic storming.
Impulsive X1.5 solar flare erupts from geoeffective Region 3764, G3 – Strong geomagnetic storm watch
An impulsive solar flare measuring X1.5 erupted from geoeffective Active Region 3766 at 02:37 UTC on July 29, 2024. The event started at 02:33 and ended at 02:43 UTC. As a result of recent solar activity, a G3 – Strong geomagnetic storm watch is in effect.
Multiple Earth-directed CMEs, significant geomagnetic storming possible
Solar activity was at very high levels over the past 24 hours, with a series of moderate to strong solar flares, including an M9.9 flare on July 28 with an Earth-directed component. This, coupled with the cannibal CME expected to arrive late on July 29 into July 30, suggests significant geomagnetic storming is possible, potentially in the range of G3 – Strong or even G4 – Severe on July 30.
Major X14 solar flare erupts on the Sun’s far side, the strongest flare of Solar Cycle 25
A major solar flare measuring X14 erupted on the Sun’s far side at 00:00 UTC on July 23, 2024, producing a full halo coronal mass ejection (CME). The event sent energetic particles throughout the solar system, including Earth, where it caused an S1 – Minor solar radiation storm.
Two Earth-directed CMEs, G2 – Moderate geomagnetic storm watch in effect
Two Earth-directed coronal mass ejections (CME) were produced over the past 3 days. The estimated time of arrival to Earth is late July 23 to midday July 24, 2024. A G2 – Moderate geomagnetic storm watch is in effect.
Powerful X1.9 solar flare erupts, producing strong CME
A powerful solar flare measuring X1.9 erupted from departing Active Region 3738 at 13:26 UTC on July 16, 2024. The event started at 13:11 and ended at 13:36 UTC.
Major X1.2 solar flare erupts from AR 3738
A major solar flare measuring X1.2 erupted from Active Region 3738 at 02:34 UTC on July 14, 2024. The event started at 02:23 and ended at 02:48 UTC.
Study reveals major impacts of G5 – Extreme geomagnetic storm on satellite operations in May 2024
Researchers from the Massachusetts Institute of Technology (MIT) investigated the significant impacts and scientific insights from the May 2024 G5 – Extreme geomagnetic storm and how it impacted satellite operations and atmospheric activities.
Old region 3664 returns with M9.3 solar flare
Old region 3664/3697 — the source of multiple Earth-directed CMEs and G5 – Extreme geomagnetic storming in May, has returned to Earth-view with a strong M9.3 solar flare at 13:01 UTC on June 23, 2024. The region is now numbered 3723. The event started at 12:51 and ended at 13:11 UTC.
G2 – Moderate geomagnetic storm watch, X1.5 flare erupts from departing Region 3697
A G2 – Moderate geomagnetic storm watch is in effect for June 10, 2024, due to the anticipated arrival of coronal mass ejection (CME) produced by a long-duration M9.7 solar flare on June 8.
