An impulsive solar flare measuring X2.5 erupted from Active Region 3576 (beta-gamma) at 06:53 UTC on February 16, 2024. The event started at 06:42 and ended at 06:58 UTC. This is the fourth strongest solar flare of Solar Cycle 25 \u2014 after X5.0 on December 31, 2023, X3.3 on February 9, 2024, and X2.8 on December 14, 2024.<\/strong><\/p>\n

A Type II (estimated velocity of 2 674 km\/s) and Type IV radio emissions were detected at 06:53 UTC, indicating a strong coronal mass ejection (CME) and solar radiation storm were associated with the event.<\/p>\n

In addition, a 10cm Radio Burst (Tenflare) lasting 5 minutes and with a peak flux of 420 sfu was also associated with the event. 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

The location of this region (SW limb) does not favor Earth-directed CMEs but S1 or greater solar radiation storm is expected.<\/p>\n

It is possible a part of the CME is Earth-directed.<\/p>\n

Radio frequencies were forecast to be most degraded over eastern Africa, the Middle East, India, China, the Indian Ocean, and western Australia at the time of the flare.<\/p>\n

Proton flux started rising at 07:10 UTC and is expected to reach S1 or greater values in hours ahead.<\/p>\n
