This is the fourth and the strongest solar flare so far this year, following X1.2 on January 3, and X1.1 and X1.8 on January 4.<\/p>\n

A coronal mass ejection (CME) was produced, but the location of the responsible region on the northwest limb does not favor Earth-directed CMEs.<\/p>\n

However, the northwest limb favors solar radiation storms, meaning there is an increased chance of high-energy proton events from this and further activity of this region.<\/p>\n

The flare was associated with a short-lived R3\u2013Strong radio blackout on the dayside of Earth, affecting high-frequency (HF) radio communication, particularly over the Pacific Ocean and parts of the Americas.<\/p>\n

Solar activity remained at moderate levels in 24 hours to 12:30 UTC today, with Region 4001 producing the strongest flare of the period\u2014an M4.9 flare at 02:13 UTC on February 23. Region 3998 generated an impulsive M1.0 flare, while Region 4000 showed signs of decay. No Earth-directed CMEs were detected.<\/p>\n

There is a chance for minor to moderate radio blackouts (R1-R2) and a slight chance for stronger events (R3 or greater) through February 25.<\/p>\n

Energetic particle flux remained at normal to moderate levels, with a slight chance for a minor proton storm (S1) through February 25.<\/p>\n

Solar wind conditions were weakly enhanced, with speeds between 300\u2013350 km\/s and intermittent southward Bz components. A weak coronal hole high-speed stream (CH HSS) influence is expected on February 24 and 25, with a possible glancing impact from a CME that left the Sun on February 19.<\/p>\n

Geomagnetic conditions were quiet to unsettled over the past 24 hours and are expected to remain so over the next few days, with potential minor disturbances from CH HSS and CME influences.<\/p>\n
