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.
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.
A strong, long-duration solar flare measuring M9.7 erupted from Active Region 3697 at 01:49 UTC on June 8, 2024. The event started at 01:23 and ended at 02:19 UTC, producing a strong CME. Shortly after, solar radiation storming began on Earth, reaching the S3 – Strong threshold at 08:00 UTC.
A long-duration M7.3 solar flare was observed on June 1, 2024, peaking at 19:39 UTC. This event, originating from Region 3697, produced an asymmetric coronal mass ejection (CME), with a possible Earth-directed component, according to SWPC.
A strong solar flare measuring X1.4 erupted from Region 3697 (ex 3664) at 08:48 UTC on June 1, 2024. The event started at 08:26 and ended at 08:58 UTC.
An impulsive solar flare measuring X1.1 erupted from Active Region 3697 at 22:03 UTC on May 31, 2024. The event started at 21:52 and ended at 22:03 UTC.
