Learn how aurora colors work. See the chemistry and physics of the northern and southern lights and how the aurora works on other planets. The aurora borealis tends to get more attention as the normal area of visibility for the aurora australis is mostly the Arctic Ocean.
Most of the time the aurora are visible between 10-20 degrees latitude from the poles (or approximately 700-1400 kilometres). The aurora borealis is often visible in Greenland, Iceland, and northern Scandinavia. COLOR CODING We have divided all of the Space Weather Action Center resources into four 'color-coded' categories: Sunspot Regions (orange), Storm Signals (green), Magnetosphere (blue) and Aurora (purple).
The same color code scheme is used in the flipchart, the data collection sheets and on the Live Data and Tutorials webpage. You can always know which section you're in with one quick. 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. Here we learn what causes the different colors in the aurora borealis (northern lights) and the aurora australis (southern lights). Aurora colors and what they mean by USAT.
The observations of the colors of the aurora, either in a broader sense by looking at the overall color balance, or by detailed spectroscopic methods, can teach us much about the physical processes that cause aurora and the effects that aurora has on the upper atmosphere. Check out this cool visualization to learn how the northern lights occur, the best places to see them and more facts about Aurora Borealis. What Do the Most Common Aurora Colors Mean? Here is an overview of some of the most common Aurora colors and what they indicate about the composition of the atmosphere where the collisions are occurring: Green The most common color of the Aurora is a pale, yellowish-green.
This is produced by collisions with atomic oxygen roughly 60 miles above the Earth's surface. Red A deep, blood red.
