Aurora, Amazing Northern Lights

• The aurora is produced by solar wind particles guided by Earth's field lines to the top of the atmosphere. This holds true for the cusp aurora, but outside the cusp, the solar wind has no direct access. In addition, the main energy in the solar wind resides in positive ions; electrons only have about 0.5 eV (electron volt), and while in the cusp this may be raised to 50–100 eV, that still falls short of auroral energies.
• After the Battle of Fredericksburg the lights could be seen from the battlefield that night. The Confederate army took it as a sign that God was on their side during the battle. It was very rare that one could see the Lights in Virginia.
