History of Space Weather
September 1, 1859 - Carrington observed a solar
flare and two days later Magnetic disturbances
in London. One swallow does not make a
summer. November 30, 1892 - Royal Society
Presidential Address It seems as if we may also
be forced to conclude that the supposed
connexion between magnetic storms and
sunspots is unreal, and that the seeming
agreement between periods has been a mere
coincidence. Lord Kelvin (old British
spelling) November, 1905 - Monthly Notices of
the Royal Astronomical Society The origin of
our magnetic disturbances lies in the Sun Prof.
Maunder Outstanding Question What from the Sun
Causes Magnetic Storms?

Space Weather Storms What do they Do?

• Interaction of Solar Wind/CMEs with Earths
  Magnetosphere
• Generates Electrical Currents, energizes
  particles (radiation), moves plasma
• heats ionosphere/atmosphere
• Compresses magnetosphere
• Loads magnetic energy into system
