Session ID#: 14733

Session Description:
Space weather events have the potential to adversely affect technological and infrastructure systems that millions depend on. Extreme events are often held to the "standard" of the 1859 Carrington-Hodgson event (arguably the most extreme space weather event in recorded history), and the likelihood that an event comparable in magnitude could reoccur. This session will discuss the current capability and research activities for predicting and understanding the effects of such events and the ability to adequately inform industry and policymakers of the risks posed. Questions addressed in this session include:

(1) What are the parameters that define an extreme event?

(2) What measurements are available that provide insight into extreme conditions?

(3) What systems are exposed and what conditions affect their performance?

(4) What is the capability to model extreme event conditions with respect to technological and infrastructure system?

(5) In what areas should new research and measurement capability be directed?
