One of the largest magnetic storms in history quantified: Aurorae from the tropics to the polar regions

In early November of this year‚ aurora borealis were observed at surprisingly low latitudes‚ as far south as Italy and Texas. Such phenomena indicate the impacts of a solar coronal mass ejection on the Earth's magnetic field and atmosphere. Far more dramatic than this recent light show was‚ it was nothing compared to a huge solar storm in February 1872.
