In this long-time exposed March 6, 2016 photo polar lights illuminate the night sky near Lietzen, eastern Germany. The Northern Lights (Aurora borealis) are produced in the earth's atmosphere by a giant cloud of electrically-charged parts of a solar storm. The color effect has been increased with a 10-second exposure. The polar light could be seen in many parts of Germany last night. (Patrick Pleul/dpa via AP)

Parts of Britain and Germany have been treated to a display of the northern lights, a colorful phenomenon that is usually only seen further north.

The aurora borealis painted skies green, purple and blue late Sunday and early Monday as far south as the southern English county of Oxfordshire, as well as in some northeastern regions of Germany.

An aurora appears when a magnetic slams into the Earth's magnetic field, exciting electrons of oxygen and nitrogen.

Amanda Townsend, a space weather adviser for Britain's Met Office, said that "once in a while the solar winds are enhanced to levels stronger than normal, with particles at higher speeds." She added that "on this occasion it has connected really well with the Earth's ."
