Although the Aurora is unique and never repeats itself, several of its types can be conventionally distinguished in terms of shape and intensity:
- the eye does not see the Aurora, the camera captures only a greenish background in the atmosphere (diffuse Aurora);
- a static white-green arc not high above the northern horizon;
- the arc is higher, it can resemble a ribbon slowly swaying in the wind. Moments of shape change can be almost invisible to the eye. The emergence of light columns.
- the Aurora is gaining "density", the green tint is more distinctly visible, the shape changes clearly for the eyes - the Aurora "runs" and "plays", it is visible higher above the horizon;
- the Aurora is of a distinctly green hue, lilac-pink tones are clearly visible, sometimes yellowness. Forms change quickly, it can split into several ribbons.
- something immense blazes in the sky from horizon to horizon. A magnificent sight!
