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.
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.
A fast halo coronal mass ejection (CME) produced by the X5.8 solar flare from Region 3664 at 01:23 UTC on May 11, 2024, is expected to merge with the previous in-transit CMEs and impact Earth by 12:00 UTC on May 12.
The first of several incoming coronal mass ejections (CMEs) impacted Earth at around 16:56 UTC on May 10, 2024, rapidly increasing geomagnetic field levels from unsettled to G4 – Severe by 17:44 and to G5 – Extreme by 23:34 UTC — something we haven’t seen since 2003.
A powerful solar flare measuring X3.9 erupted from Active Region 3664 at 06:54 UTC on May 10, 2024. The event started at 06:27 and ended at 07:06 UTC. This is now the 10th X-class solar flare since May 3.
