The distance rings are 50% of the real range, this display is 1200km.
This display will only display strikes that are correlated between at least two lightning trackers.

That means the difference between this display and the Bergen only display will usually be different,
but the strikes visible on this display will usually give you a more accurate position of where the
lightning activity is.

This display updates only every five minutes and I chose to display all strike types the same,
since this is only a kind of calibration display and not the main one.
