Lightning across Europe

Lightning map of Europe http://www.blitzortung.org/Webpages/index.php?lang=en

Sometimes it is useful to know where there are lightning strikes taking place across Europe: for example, there are some theories linking sporadic-E propagation to a secondary effect of lightning, although I forgot where I read this. Also, it is useful to know how noisy the VLF and LF bands are likely to be as a result of sferics from such strikes.

Well, http://www.blitzortung.org/Webpages/index.php?lang=en gives a map showing this data.
