A powerful solar flare registered as X3.4 erupted from Active Region 3664 \u2014 now located beyond the west limb \u2014 at 08:37 UTC on May 15, 2024. The event started at 08:18 and ended at 08:52 UTC. A solar radiation storm continues at S1 \u2013 Minor to S2 \u2013 Moderate levels since May 13.<\/strong><\/p>\n

This event follows three X-class flares from the same region on May 14, including X8.7 \u2014 the strongest solar flare of the current solar cycle (Solar Cycle 25). This was also the strongest flare since X9.3 on September 10, 2017 \u2014 the strongest solar flare of Solar Cycle 24.<\/p>\n

While today\u2019s X-class flare was registered as X3.4, due to the location of this region behind the edge of the disk, it was probably much stronger than that.<\/p>\n

A Type IV Radio Emission was associated with this event, suggesting a strong coronal mass ejection (CME) was produced.<\/p>\n

In addition, a 10cm Radio Burst (tenflare) with a peak flux of 450 sfu was detected from 08:30 to 08:35 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. The 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 Europe, Africa, Asia, and the Indian Ocean at the time of the flare.<\/p>\n

The location of Region 3664, now beyond the west limb, no longer favors Earth-directed CMEs. The region will traverse the farside of the Sun and reemerge into Earth\u2019s view in about two weeks if it survives.<\/p>\n

Powerful flaring from this region over the past couple of days is still reflected on Earth in the form of solar radiation storming, with periods of S1 \u2013 Minor to S2 \u2013 Moderate storming observed since 13:50 UTC on May 13.<\/p>\n

During S1 \u2013 Minor solar radiation storms, satellites may encounter operational issues and communication disruptions, while the International Space Station (ISS) and its crew face elevated radiation risks. Additionally, High-Frequency (HF) communication in polar regions can be affected.<\/p>\n

S2 radiation storms exacerbate these effects, presenting higher radiation risks to passengers and crew on high-altitude aircraft, potentially causing satellite malfunctions, radio blackouts, and disruptions in radio communication due to ionospheric disturbances.<\/p>\n

Solar activity is expected to be at high levels due to M-class flare activity (75%) with a chance for X-class
flares (40%) on May 15. The odds drop to 40%\/15% on May 16 and to 35%\/10% on May 17.<\/p>\n
