The center, a division of the National Weather Service, issued a modern geomagnetic storm watch, known as a G2, for Friday and Saturday.
Unlike the G5, or extreme geomagnetic storm, that occurred on May 10, moderate storm watches are not uncommon, according to the center.
But the aurora-causing solar flares and coronal mass ejections currently spewing from the sun are a result of the same sunspots that triggered solar activity in May, according to Dr. Ryan French, solar physicist at the National Solar Observatory in Boulder, Colorado.
“The frequency of things is decreasing, but you only need one to cause a large geomagnetic storm.
The solar storm on May 10 was the most successfully mitigated space weather storm in history, Dahl said.
