An impulsive X4.2 solar flare erupted from geoeffective Active Region 4366 at 12:13 UTC on February 4, 2026.
The flare originated from a magnetically complex beta-gamma-delta region that produced dozens of M- and 5 other X-class flares since February 1.
Its location near the central solar disk raises the possibility of Earth-directed coronal mass ejections (CMEs) this week.
