LightningMaps.org: Real-time Lightning Map

[Jonathan.Williams]

Hi folks,

here is something new: http://www.lightningmaps.org/realtime

Interesting but quite cryptical...
What do colors mean?
What does circle radius mean?
What do expanding circles mean?
Does it exist a wiki?

The colors for strikes indicate age, with white being the newest strikes and shading to dark red/brown for the oldest.

The colors of the lines to stations indicate distance.

The expanding circles when zoomed out are for clarity. When zoomed in, the slowly-expanding circles represent estimated thunder sound fronts.

Also, when zoomed in, the fixed circles around each strike indicate estimated locating error.
