Lightning by Blitzortung network stations

Lightning Map Courtesy of hobbyist lightning detection network.
Data supplied by Blitzortung network members using their home-built Blitzortung hardware.

The Blitzortung networks members build (from kit parts) the detector which monitors H-field (and now can do E-field) emissions from lightning strikes, and has a set of servers in Europe to correlate the Time-Of-Arrival at detectors v.s. GPS-time and uses that to locate strikes. There is a great (and somewhat hypnotic) realtime map for North America where you can see real-time strike info, and which stations participated in the location of that strike. There is a companion site that offers the same data and uses a zoomable Leaflet Map for display.

For those interested in more information about Blitzortung, there is a Blitzortung forum in the US at and a public forum .. to access the internal forum, there, you'll need to have a Blitzortung member id.
