A significant X8.1 solar flare erupted from sunspot 4366, the third largest of solar cycle 25. The flare caused a radio blackout across the sunlit side of the planet, centred around the Pacific. The sunspot, which has grown rapidly in size, is expected to produce more flares, potentially even stronger ones.

The X7.1 solar flare from 2024 is expected to impact Earth, potentially triggering increased earthquake activity, particularly in areas like Southern California. The sunspot responsible for the flare has rapidly grown in size and complexity, suggesting the possibility of even larger flares in the future. The updated image of the flare is described as stunning and will be used for the video’s thumbnail.
