NOAA space weather forecast, March 7,

March 7, 2012

Uploaded by on Mar 7, 2012

This forecast model run from NOAA’s space weather experts suggests that Tuesday evening’s coronal mass ejection — a blast from the sun’s outer atmosphere — could reach Earth by early Thursday morning.

The sun is yellow in center; Earth is smaller green dot to the right.

Geomagnetic storms from these kinds of space weather events can affect the power grid, navigation systems and other technologies. NOAA provides space weather forecasting for the nation, and forecasters at NOAA’s Space Weather Prediction Center are issuing updates regularly.
The impressive flare from Tuesday evening, and a corresponding radiation storm are already triggering high-frequency radio outages at Earth’s poles, which could last a day or more, and possible temporary outages on parts of the day-lit Earth.
