SUMMARY:CSDA Seminar: Richard Horne
TZID:Europe/London
UID:20220125-8a1785d87d765031017d9c082c5c23b2@warwick.ac.uk
CREATED:20220125T053110Z
DESCRIPTION:Richard Horne\, FRS\, is the Head of Space Weather and Atmosp
 here at the British Antarctic Survey\, and an Honorary Professor at the 
 University of Sheffield. A full biography can be found here. Severe Spac
 e Weather and Satellites Large explosions on the Sun can expel billions 
 of tons of charged particles and magnetic field out into space in what i
 s known as a coronal mass ejection. When this plasma encounter’s the Ear
 th’s magnetic field it can tear open the outer layers and cause a geomag
 netic storm which can last for days. The Sun can also emit intense radia
 tion from solar flares and drive radiation storms where high energy part
 icles penetrate the Earth’s magnetic field\, particularly in the Polar R
 egions. In this talk we describe how space weather can affect the power 
 grid causing disruption to power supplies\, pose a radiation risk to avi
 ation\, damage satellites\, interrupt communications and GPS signals and
  increase the risk of collisions between satellites and space debris in 
 low Earth orbit. We discuss some of the uncertainty over the economic im
 pact and what mitigation measures can be taken. Finally\, we discuss som
 e of the challenges around forecasting space weather now and into the fu
 ture and describe a new forecasting system that we have developed for th
 e European Space Agency that is now being used to help protect satellite
 s on orbit from charged particle radiation. Room H0.51\, or join virtual
