The 35th General Assembly of the International Union of Radio Science, held in Sapporo Japan, included a few general lectures given to the whole assembly by invited speakers – the objective being to acquaint an international gathering of specialist radio scientists with the “state of the art” in related radio fields. Craig Rodger was invited to deliver one of these lectures, which was on the topic of “Space weather disturbances in electrical power networks – preparing for an extreme event”, and hence strongly based on our New Zealand focused Solar Tsunamis work! These photos show Craig in the conference “Main Hall”, delivering the General Lecture.
