Here's something that will keep you occupied for awhile.  It's like a cat watching a fish in an aquarium.  Fascinating weather stuff!

Blitzortung.org map

The company explains its ability this way:

"Blitzortung.org is a lightning detection network for the location of electromagnetic discharges in the atmosphere (lightning discharges) based on the time of arrival (TOA) and time of group arrival (TOGA) method. It consists of several lightning receivers and one central processing server. The stations transmit their data in short time intervals over the Internet to our server. Every data sentence contains the precise time of arrival of the received lightning discharge impulse ("sferic") and the exact geographic position of the receiver.

Got that?  Enjoy!
