An uncommon double solar eruption has sent two coronal mass ejections towards Earth, which are expected to arrive Wednesday.
The event could cause glowing in the atmosphere and damage electrical infrastructure when it arrives, but we won't know the severity of the event until it's near.
The storm should arrive today or tomorrow, and could bring with it some brilliant auroras.
While the storm could pose a threat to fragile electric systems, the National Oceanic and Atmospheric Administration says the danger is minor.
