A long-duration solar flare measuring M5.5 erupted from an emerging region on the southeast limb of the Sun at 13:22 UTC on September 1, 2024. The region was numbered 3813 on September 2.
The coronal mass ejection (CME) produced by the X1.3 solar flare on August 14, 2024, impacted Earth around 14:30 UTC on August 18, producing G3 – Strong geomagnetic storming.
A major, long-duration solar flare measuring X1.1 erupted from a large, geoeffective Active Region 3784 at 06:40 UTC on August 14, 2024. The event started at 06:00 and ended at 07:08 UTC.
A G3 – Strong geomagnetic storming was observed on August 12, 2024, following multiple impacts from coronal mass ejections (CMEs) produced since August 7.
A major, long-duration solar flare measuring X1.3 erupted from Active Region 3777 at 19:35 UTC on August 8, 2024. The event started at 19:01 and ended at 19:57 UTC.
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.
NASA scientists have discovered a transient third Van Allen radiation band encircling Earth, created by powerful solar storms in May 2024.
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 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.
