An incoming geomagnetic storm is expected to hit the Earth today, according to the Space Weather Prediction Center. If the storm hits at its expected strength, it could push the northern lights ...
The 2003 Halloween solar storms had a peak Dst index of −383 nT, although a second storm on 20 November 2003 reached −422 nT while not reaching G5-class. [16] [17] The March 1989 geomagnetic storm had a peak Dst index of −589 nT, [18] while the May 1921 geomagnetic storm has been estimated to have had a peak Dst index of −907 ± 132 nT.
A severe geomagnetic solar storm could bring colorful auroras to the night sky across parts of the nation for a third night in a row. The auroras could be seen as far south as Alabama and west to ...
