This site sponsors the daunting task of actually plotting  in real time where  the Schumann Cavity lightning events occur.  There

are few Q burst per other lightning events.  Most of the cavity events plotted will not qualify as Q burst but are much stronger than normal

                  lightning.  Many thanks to all who have helped in development by using their stations to operate and test things never tried before.

Below is a test of the system done on 21 Feb 17.  Sven Nortin's station in Handen Sweden using his Magnetic antennas and a station in San Antonio Texas, USA using a Power Grid  antenna for 7.8 Hz reception of Schumann signals.  5000 miles between stations.  Stations were in the single station mode using beam generators across wide areas of he African, and Indian oceans. Virtual stations used for triangulation of strikes.  See Sven's page for other information on his station in the left index list.

Using the strike counting system described on these pages. Schumann 7.8 Hz Cavity

5000 Miles away in San Antonio Tx. this plot was captured at the same time using the Power Grid as an ant. Capture frequency was 7.8 Hz using the strike counting mode of the digital receiver. A Power Grid antenna has a E field 360  degree beam, with 250,000 miles of wire in the air!

Counted strike intensity over selected area.



The project below was done to prove ,/document and use the power grid as a source of Schumann signals.

Lightning Radar has been using this mode for some time. The other project on these pages.
