Earth is bracing for a 'severe' geomagnetic storm and it probably won't be the last for this year

• NOAA has forecasted a "severe" geomagnetic storm to hit Earth this Friday, triggering aurora borealis.
• This storm comes as we approach solar maximum: the peak of solar activity during the sun's 11-year cycle.
• That means that this year, we could see more storms like this one.

A cluster of giant sunspots called region 3664 has been shooting out powerful eruptions, called coronal mass ejections, over the last several days.
