Scientific paper

The discovery of frequent lightning discharges on Venus by the Groza instrument on board the Venera 11 and 12 spacecraft is reported. The experiment measured impulses of the electromagnetic radiation produced by lightning discharges using a radio receiver/spectroanalyzer in the range 8 to 90 kHz and a discharge rate counter. During spacecraft descent to the planet's surface, approximately 1000 impulses were recorded at discharge rates usually between 20 and 30/sec, but occasionally reaching up to 50/sec; impulses were also recorded at a lower frequency on the surface. Results indicate the local nature of the thunderstorms giving rise to the lightning. The glow of the Venus nightside observed from the earth is attributed to the high lightning activity.
