The colors of the aurora largely result from light released by excited oxygen atoms and nitrogen molecules and ions. Have you ever wondered how aurora colors work and why sometimes the aurora is just green or red, while other times it is a whole rainbow of hues? The short answer is that nitrogen and oxygen in the upper atmosphere release light in specific colors in response to solar radiation. Here we learn what causes the different colors in the aurora borealis (northern lights) and the aurora australis (southern lights).

Green: Green is the most common colour seen from the ground and is produced when charged particles collide with oxygen molecules at altitudes of 100 to 300 km. Pink and dark red: Occasionally, the lower edge of an aurora will have a pink or dark red fringe, which is produced by nitrogen molecules at altitudes of around. Figure 2.
Green curtains and rays above the Brooks Range and Gates of the Arctic National Park. D. Lummerzheim Abstract The aurora has fascinated observers at high latitudes for centuries, but only recently have we begun to understand the processes that cause it.
This article discusses the mechanisms that are responsible for the colors of the aurora. Observations of color balance in aurora can. The majority of auroral displays are predominantly green for two reasons: the first of which is that the human eye detects green more readily than other colours.
This is why photographic images of the Northern Lights will often show colours that were not visible at the time to the naked eye. However, the main factor in determining the colours of any given display is the altitude at which the. The northern lights can be green, red, pink, blue or purple.
Here we look at the cause and meaning behind all the different aurora colours. Why Are Auroras Green? The green color of auroras is produced by oxygen atoms located about 60 miles above the Earth's surface. When charged particles from the solar wind slam into the atmosphere, they excite oxygen atoms causing them to light up.
The color of the aurora depends on which atmospheric gas is colliding with the charged particles. Here's a breakdown of the colors: Green. #6adc99 color RGB value is 106, 220, 153 and the CMYK value is 0.518, 0.00, 0.305, 0.137.
Names for that color are: aurora green, turquoise, mediumseagreen, emerald. Other colours, and why cameras see them better While green is the most common colour to see in the aurora, and red the second most common, there are also other colours.
