(NEXSTAR) — Some in the U.S. could have another chance to see the northern lights this weekend thanks to a coronal hole and accompanying solar winds that may impact Earth.

NOAA's Space Weather Prediction Center has issued a geomagnetic storm watch for Saturday because of the coronal hole, or CH. These are areas on the sun that are cooler and less dense regions of open and unipolar magnetic fields, NOAA explains. Their openness allows solar wind to escape at higher speeds, known as High Speed Streams, or HSS.

A CH HSS can spark geomagnetic storms on Earth, according to NOAA, though not typically as strong as those brought on by coronal mass ejections, like we saw earlier this month.

The CH HSS could still pack a punch to our atmosphere, however. While there could be some........
