A geophysical experiment detected unusual seismic signals associated with tornadoes that recently struck regions across the Midwest — information that may have value for meteorologists studying the atmospheric activity that precedes tornado disasters.

A pair of unusually large solar flares early March 7, 2012 generated a Coronal Mass Ejection that was expected to reach Earth around mid-day March 8. It will likely cause at least a strong geomagnetic storm that could affect satellites in space and trigger auroral displays. The effects at ground level are expected to be limited, but there is a good chance for some excellent auroral displays in the north.
