Low, Middle and High Latitude

When you read forecasts about possible chances to see the aurora we speak often about the high, middle and low latitudes. But what do they mean?
There is no exact definition where that boundary lies but the high latitude is situated around the 60° magnetic latitude and higher; the middle latitude between the 50° and 60° magnetic latitude and everything below the 50° magnetic latitude is concidered to be in the category of low latitude.
The image below will make this more clear for your region.

For example, the website is made in Belgium and Belgium is at the 51° geographic latitude and is concidered to be in the lower middle latitude. If I would travel to Paris (France) I would be in the low latitude area.

You can also compare it with the Kp-index, for the middle latitudes a Kp-index of 7 through 8 is required. In the lower latitudes a Kp of 9 is required.
