(CNN) — A large solar flare erupted Thursday and is set to reach Earth Saturday, which could result in a strong geomagnetic storm and cause the aurora borealis, or Northern Lights, to be visible across the US and Europe. NOAA issued a G3, or "strong" geomagnetic storm watch, for Saturday and Sunday ahead of the flare slamming into the Earth. This geomagnetic storm could cause voltage irregularities and false alarms on some protection devices, NOAA warns. The most visible effect from the impending geomagnetic storm is it will likely supercharge the aurora borealis, making it visible across large parts of the US and Europe.
