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.<\/strong><\/p>\n

There were no radio signatures associated with this event that would suggest a coronal mass ejection (CME) was produced.<\/p>\n

Radio frequencies were forecast to be most degraded over the United States, Canada, and the Pacific Ocean at the time of the flare.<\/p>\n

The region has a \u2018beta-gamma-delta\u2019 magnetic configuration and is capable of producing more strong to major eruptions on the Sun.<\/p>\n

This was the strongest flare over the past 36 hours. The previous X-class solar flare was a long-duration X1.4 on May 29.<\/p>\n

\u201cThis is now the 48th<\/sup> X-flare of the current Solar Cycle 25, leaving us just one behind the total amount of X-flares during the entirety of the previous Solar Cycle 24,\u201d said Kevin VE3EN of SolarHam.com.<\/p>\n

Region 3697 (previously numbered 3664) exhibited growth in the intermediate spot area and a delta configuration persisted in the leader spot area over the past 36 hours. The region also produced an M1.0 flare at 11:20 UTC on May 31. <\/p>\n

C-class flare activity was observed from Regions 3691 (beta-delta), 3697, and 3698 (beta). Region 3691 showed an overall decay trend and magnetic simplification throughout the period. <\/p>\n

New Region 3699 (beta) was numbered and exhibited minor growth since emerging. <\/p>\n

Region 3698 continued to grow in size and total spot count.<\/p>\n

Other activity over the same period included instability along a filament centered near S20E10 at around 08:00 UTC on May 31, but the filament did not lift off. <\/p>\n

No Earth-directed CMEs were observed.<\/p>\n

Solar activity is expected to continue at moderate to high levels through June 3, with occasional M-class flares and a chance for isolated X-class flare activity.<\/p>\n

Solar wind parameters were slightly enhanced over the period. The total field ranged from 1 \u2013 9 nT. Prolonged periods of southward Bz reaching -7 to -9 nT were observed between 00:23 and 05:14 UTC on May 31. Solar wind speed averaged near 350 km\/s while the phi angle was variable.<\/p>\n

The geomagnetic field was at quiet to unsettled levels, with an isolated period of G1 \u2013 Minor geomagnetic storming between 03:00 and 06:00 UTC following a prolonged period of southward Bz and elevated density. <\/p>\n

Looking ahead, G1 \u2013 Minor to G2 \u2013 Moderate geomagnetic storming is likely on June 1 due to flanking effects from the May 29 CME. Quiet to unsettled levels are expected on June 2 and 3.<\/p>\n
