Lightning appears on the map by the two symbols in the lower left corner of the image. The map shows a shaded area where only lightning within the Norwegian, Swedish and Finnish economic zone is plotted. These symbols indicate if lightning strikes the ground or whether it stays inside the clouds. Lightning within the last 11 minutes before the radar observation time appear with a black symbol. Lightning registered by radar observation point, indicated by a blue symbol and added over the black. The red number represents the total number of lightning throughout the period.
