A powerful X-class solar flare, classified as X1.1, was detected on the Sun during the night of June 30 to July 1, 2026, at approximately midnight Moscow time. Despite being categorized as the highest level, it was described as moderately strong. Scientists anticipate a significant geomagnetic storm (G3) reaching Earth within 24 hours due to the alignment of solar activity with Earth.
Consensus
- A powerful X-class solar flare (X1.1) occurred on the Sun during the night of June 30 to July 1, 2026
- The event was detected by the Laboratory of Solar Astronomy at the Institute of Cosmic Research (IKI RAS)
- The flare happened near midnight Moscow time, around 23:50 UTC
- Scientists expect a significant geomagnetic storm (G3) to reach Earth within 24 hours
Points of divergence
- The X-flare was expected and preceded by increased solar activity including two M-class flares on June 30th, with a total of 17 flares in the previous day — fontanka
- The flare occurred after an increase in solar activity that began with 17 flares within one day and was linked to a large sunspot group formed on June 28th — kommersant
- A previous X-class flare had been recorded by the same laboratory on May 7, 2026, with an M-class flare lasting 70 minutes — vm
- Three strong flares were registered on June 30th including two M1.3 and M1.4 flares and one M5.9 flare in the same sunspot group, with a comet's destruction also noted — m24
