Variables¶
Aurorae are automatically generated by trueSKY providing that some conditions are met. You need to be within the Auroral Oval with the generated aurorae within the view distance.
Aurorae can be customised, from global position to strength and auroral colours.

Geomagnetic North Pole Latitude |
The latitude of the geomagnetic north pole, about which aurorae are generated. |
-90.0 to 90.0 |
Geomagnetic North Pole Longitude |
The longitude of the geomagnetic north pole, about which aurorae are generated. |
-180.0 to 180.0 |
Highest Latitude |
The highest latitude aurorae can occur, in degrees decimal centred about the geomagnetic north pole. |
0.0 to 90.0 |
Lowest Latitude |
The lowest latitude aurorae can occur, in degrees decimal centred about the geomagnetic north pole. |
0.0 to 90.0 |
Max Band |
