A geomagnetic storm occurred last month when the sun had a giant eruption on its surface. It’s called a coronal mass ejection. The sun emitted a mass of gas that moved toward Earth at 2 million miles per hour. Sun storms can interfere with high-frequency airline and radio communications, but didn’t this time. Normally the storm cycle is every eleven years, but this storm was 3 years late. The good news is the storm causes an abundance of northern lights activity, which could occur for several more weeks. They may be active enough to be seen very far south, and may be visible from Northwest Indiana.
