On the night of June 17, around 00:49 Moscow time, a powerful X1.2-class flare occurred on the Sun. The event was recorded in active region No. 4114, where two significant flares of level M8.4 and M6.3 had already been observed earlier, on June 15 and 16. According to space observatories, this zone remains geoeffective, that is, capable of influencing the Earth, as it is located close to the central solar meridian.
The red-hot mass ejected by the explosion has not yet appeared in the field of view of space coronagraphs. Scientists expect that it will be possible to record it in at least an hour. Previous flares in this region were also accompanied by coronal mass ejections (CME), but their trajectories did not affect our planet. If there have been no significant changes in the global configuration of the Sun's magnetic field over the past two days, there is a possibility that the new ejection will pass by the Earth along the same trajectory.
In 2025, this is already the eighth X-class flare, and the current one ranks fourth in power. The record of the year is still held by the X2.7 event of May 14.
