NASA Captures Butterfly-Shaped Coronal Hole on the Sun, Sending Solar Wind Toward Earth

On September 11, 2025, NASA captured a remarkable image of a massive butterfly-shaped coronal hole on the Sun’s surface. This solar feature is releasing a strong stream of charged particles, known as solar wind, which is expected to reach Earth around September 14, 2025.

These powerful solar winds can trigger geomagnetic storms, potentially affecting satellites, communication systems, and other technologies. The risk is especially high near equinoxes due to the alignment of the Sun’s and Earth’s magnetic fields—a phenomenon called the Russell-McPherron effect.

Stay alert as this cosmic event unfolds, as it could bring dazzling auroras and notable impacts on our technological infrastructure.
