Capstone Keynote Lecture to Feature Space Weather Expert
Capstone Keynote Lecture
When: Wednesday, May 9th at 7:30 pm
Where: Mamma Maria’s Italian Restaurant, East Grand Forks, MN
Dr. David H. Boteler
Research Scientist with the Canadian Space Weather Forecast Centre operated by Natural Resources Canada
Title: Space Weather Effects on Technology
About the Topic:
There is a growing realisation that there is a new natural hazard affecting technological systems: “Space Weather”. Eruptions on the Sun produce clouds of plasma that stream through interplanetary space. If they interact with the Earth’s magnetic field they can produce a wide range of effects that can affect modern technology. High energy electrons and protons go though the skin of a spacecraft and cause damage to the circuitry inside. Particle precipitation into the ionosphere causes changes that disrupt high-frequency radio communications and interfere with the radio signals used for GPS positioning. Electric currents in the ionosphere create magnetic disturbances that drive geomagnetically induced currents in power systems and pipelines that can produce power blackouts or cause pipeline corrosion. This talk will describe the space weather phenomena and how it affects different technologies, as well as examining some historic events and explain why there is growing concern about how space weather can affect modern society.
About the Speaker:
