Center; blue overlay dots are WWLLN Lightning; Red circles are WWLLN receivers; Red line is the terminator) University of Washington in Seattle operating a network of lightning location sensors at VLF (3-30 kHz). Most ground-based observations in the VLF band are dominated by impulsive signals from lightning discharges called “sferics”. Significant radiated electromagnetic power exists from a few hertz to several hundred megahertz, with the bulk of the energy radiated at VLF. With our network of sferic sensors we are producing regular maps of lightning activity over the entire Earth. Our map showing the entire world uses coloured spots to indicate lightning st*okes (red stars inside an open circle are active WWLLN lightning sensor locations).  The WWLLN Management Team, lead by Prof Robert Holzworth of the University of Washington produced these data and images with the cooperation of the universities and institutes which host the stations as listed below. We currently have over 70 sensors around the globe to detect sferic activity in the VLF band, listed below in the order of their Cold and Arid Regions Environmental and Engineering Research Insitute, Chinese Academy of Sciences Herman*s Magnetic Observatory and University of KwaZulu-Natal (South Africa) Center for Geophysical Research (CIGEFI), University of Costa Rica (Costa Rica) Yu.G.
