Questions people are asking

What is a geomagnetic storm?

A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave and/or cloud of magnetic field that interacts with the Earth's magnetic field.

What causes the northern lights?

The northern lights are caused by the interaction of solar wind and magnetospheric charged particles with the Earth's upper atmosphere.

What states may see the northern lights?

Forbes has published a list of 10 states where the northern lights may be visible. The Weather Channel has also published a list of states where the northern lights may be visible. However, the lists do not match.

What happened

A geomagnetic storm watch is in effect from August 27 to August 29. The storm is expected to make the northern lights visible in several states. The storm is the result of a solar flare. The Weather Channel and Forbes have both published lists of states where the aurora may be visible.
