The Sun experienced its first X-ray flare of the year.

Solar flare X1.95 of January 18, 2026

A solar flare of magnitude X1.95 occurred—the first in 2026 and the largest since November 14, 2025. The peak emission was recorded at 6:09 PM UTC. The first images of the event are being received from orbit. The explosion is quite large—it essentially involved the entire central region of the Sun, approximately half a million kilometers in size. Apparently, the flare resulted in the complete or partial destruction, followed by the ejection of two large prominences into space. These prominences have been visible on the Sun for several days to the right and above the epicenter. The newly received images show the ignition of bright ribbons, the outlines of which coincide with the position of the prominences, indicating their active explosive destruction. Rapid movements of matter in the explosion region are also directly visible, indicating the ejection of plasma into space, the mass of which will increase due to the destruction of the prominences. Within 1-2 hours, the results of direct observations of the plasma cloud in the near-solar space should be received, after which the direction of its movement will become clear, but with the explosion site in such a position (directly in the center of the visible solar disk), the cloud simply has nowhere else to fly except towards Earth.
