Massive explosions occur in succession on the Sun! Watch for geomagnetic storms and auroras from X-class solar flares

Explanation

From June 30 to July 5, 2026, X-class solar flares—the largest category on the Sun's surface—were observed occurring one after another, with nearly 10 medium-sized M-class flares also occurring during that period. The flares were accompanied by "coronal mass ejections (CMEs)," in which large amounts of plasma and magnetic field are released from the Sun, and part of this was directed toward Earth, causing a "geomagnetic storm" that disturbed Earth's magnetic field. While charged particles colliding with the atmosphere may make auroras visible even at low latitudes, there is also a risk of errors appearing in GPS positioning systems such as car navigation.
