Aurora (astronomy)

In astronomy, an aurora is a colorful display of light that results from particles in solar wind interacting with a planet's magnetic field. 
On Earth, the aurora that appears at the North Pole is called aurora borealis. (, )
Aurorae sometimes occurred over Ni'Var. ()
In 2270, Spock noted that the historical records of the Dramen star system were "spotty, at best, going back nineteen years," reporting that "mostly, they're technical data, meteor showers, auroras, [and] radiation reports." ()
