Which Aurora Data?

[timetraveller]

Hi Simon,

I love your World map, and especially the auroral overlay.

Can you expand briefly on where the overlay draws its data from? The auroral overlay seems to be a little bit expanded over the familiar NOAA's latest visual map. Possibly you are depicting the influence to radio propagation and not the visual aspect.

Thanks for a great program!
