Green: The Most Common Color

While witnessing the breathtaking display of the Northern Lights, you’re most likely to see shades of green dancing across the night sky. This is because green is the most common color of the aurora borealis, and it’s not hard to understand why.

Why Green is Dominant

On average, the altitude at which the aurora occurs is around 100-200 km, where the atmosphere is rich in oxygen atoms. When these atoms collide with energetic particles from the sun, they emit a greenish-blue light at a wavelength of around 557.7 nanometers, making green the dominant color of the Northern Lights.

Variations of Green

Any observer of the Northern Lights will notice that the green hue can vary in intensity and shade, ranging from a bright, vibrant green to a soft, pale mint.

Variations in the green color are due to the energy level of the particles colliding with the oxygen atoms. If the energy is high, the resulting green color will be more intense and vibrant. Conversely, lower-energy collisions produce a softer, more pale green. Additionally, the altitude at which the collision occurs also affects the shade of green, with higher altitudes producing a more blueish tint and lower altitudes producing a more yellowish hue.

Red: The Elusive Color

Now, when you think of the Northern Lights, you might imagine vibrant greens and blues dancing across the night sky. But, have you ever wondered about the elusive red hues that sometimes make an appearance?
