(CBS SF) — A second strong solar storm this week is predicted to slam Earth Wednesday, causing fluctuations in the power grid and GPS while sparking bright auroras across the world.
According to SpaceWeather.com, a “coronal mass ejection” erupted Monday and is expected to hit the Earth with electromagnetic radiation starting Wednesday at about 10 p.m. PDT and until Thursday.
At the same time, a geomagnetic storm that began Monday continues to rage on at severe levels, pushing glowing polar auroras to places where most people can easily see them.
NOAA forecasters said the Northern Lights may be able to be seen Tuesday night as far south as Nebraska and Indiana. But the second solar storm could continue dazzling skywatchers in both Northern and Southern hemispheres until Thursday night.
Here are some of photos of Tuesday night’s auroras, starting with this shot taken NASA astronaut Scott Kelly from the International Space Station.
