This results in bursts of light, called photons, which then make up the aurora. Collisions with oxygen produce red and green auroras, while those with nitrogen result in pink and purple ones. This reaction surrounds the polar regions of the earth, occurring at an altitude of 65 kilometres to 650 kilometres in a zone called the “Aurora Oval”. space weather forecast from NOAA Soft serve on FB Photo tip: 8 sec, f/2.8 ISO 1600
