A a strong solar radiation storm is expected to cause more trouble with electrical grids, satellite and radio signals.
It's the strongest such storm to hit us since 2005. A coronal mass ejection -- or storm on the sun -- is sending a burst of radiation toward Earth. Radiation levels are expected to be strongest around 6:00 AM Tuesday.
NOAA's Space Weather Prediction Center has issued a Geomagnetic Storm Watch for level G2, possibly G3, meaning it's strong enough to disrupt electronics.
Our atmosphere protects people and animals from harm. However, astronauts and crews in high-flying aircraft have to take special precautions.
Such events are normal for our sun. They come in cycles and are expected to increase.
