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 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.
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.
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.
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.
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.
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.
