A severe geomagnetic – or "solar" – storm hit the Earth on Monday, which may bring gorgeous auroras but also power disruptions.
The storm, which hit the Earth at around 2:39 p.m. ET, is a "G4" on the five-point scale, according to NOAA's Space Weather Prediction Center (SWPC).
"This is the very early stages of an event that will play out over many hours, with SWPC forecasting continuing storm level intensities into tomorrow," the prediction center said Monday afternoon.

This storm is the same level of the storm that hit Earth back in March.
These types of "storms" are part of what's known as space weather, when energy that blasts off from the sun (in the form of coronal mass ejections) then interacts with the Earth's atmosphere and geomagnetic field.
The electric power grid, and the power to homes and business, can be affected by solar storms like this, NOAA said, though there have been no reports yet Monday.
There is also a solar radiation storm occurring, which can impact airplane flights near and over the poles.
