A major, long-duration solar flare measuring X1.4 erupted from Active Region 3697 (previously numbered 3664) at 14:37 UTC on May 29, 2024. This is the second X-class solar flare since May 27.<\/strong><\/p>\n

A Type II Radio Emission with an estimated velocity of 878 km\/s was associated with the event, suggesting a coronal mass ejection (CME) was produced.<\/p>\n

A Type IV Radio Emission was registered at 14:48 UTC. Type IV emissions occur in association with major eruptions on the Sun and are typically associated with strong coronal mass ejections and solar radiation storms.<\/p>\n

In addition, a 10 cm Radio Burst (tenflare) with a peak flux of 300 sfu was registered from 14:21 to 14:24 UTC. A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.<\/p>\n

Radio frequencies were forecast to be most degraded over the Americas, Atlantic Ocean, Europe, and west Africa at the time of the flare.<\/p>\n

Solar activity was at moderate levels in 24 hours to 12:30 UTC on May 29 due to M1 flares at 01:06 and 06:45 UTC from Region 3697 (beta-gamma-delta).<\/p>\n

This region was previously numbered 3664. It produced around 100 M-class and over 10 X-class solar flares during its last rotation through the Earth side of the Sun in the first half of May. Multiple CMEs it produced at the time resulted in a\u00a0G5 \u2013 Extreme geomagnetic storm \u2014 the strongest since 2003\u00a0\u2014 on May 10 and 11. On May 14, this region produced\u00a0X8.7 solar flare \u2014 currently the strongest solar flare of Solar Cycle 25. <\/p>\n

Over the past 24 hours, slight growth was observed in the group as it rotated further into view but it has shrunk considerably since its last rotation.<\/p>\n

The location of this region currently does not favor Earth-directed CMEs but this will change in the days ahead as it rotates toward the center of the disk.<\/p>\n

Region 3691 (beta-gamma-delta) also produced an M1 flare at 11:21 UTC today. This region exhibited slight growth and consolidation in its leading spots. The rest of the spot groups were relatively stable or in decay.<\/p>\n

Solar activity will likely reach moderate levels with a few M-class flares while maintaining a chance for isolated X-class flares through May 31.<\/p>\n

Isolated active levels, with a chance for G1 \u2013 Minor storming, are possible late on May 29 with any shock arrival from the May 27 CME. Quiet to unsettled conditions are expected on May 30 as any lingering shock effects wane. Mostly quiet conditions are anticipated to prevail on May 31.<\/p>\n
