Heliophysics: Science of Space Weather [Sessions 6 & 7]

 

Wednesday, 9 January; 8:30 AM –1:15 PM

AMS 2013

As part of the 10th Conference on Space Weather at the AMS 93rd Annual Meeting, there will be a special half-day session on Heliophysics: Science of Space Weather

Heliophysics is the science of space weather—i.e., solar storms and their impact on Earth. It is based on a simple idea that challenges orthodox thinking. For most of the history of science, we have thought of the Sun and Earth as distinct bodies. In fact, they are one.  Measurements by NASA satellites prove that Earth is magnetically joined to the Sun.  You can actually trace lines of magnetism uninterrupted from Earths poles across the gulf of 93 million miles to the solar surface.  Guided by these connections, events on the Sun can have surprisingly direct effects on our planet—such as the great Quebec Blackout of March 1989, an event which looms larger in our thinking as the 21st century unfolds. Heliophysics treats the Sun and Earth as a united system, and thus provides a scientific foundation for forecasting of space weather events.

Researchers call the domain of heliophysics “the heliosphere,” and it is in fact much bigger than the Sun-Earth system. This new field stretches wherever the solar wind magnetic fields interconnect and encompasses whatever the Sun’s radiation touches. Every planet, asteroid, comet, moon and spacecraft in the Solar System lies inside the vast realm of the heliosphere.

This special session seeks to introduce attendees to the new field of heliophysics, and broaden understanding of the connection between the Sun and Earth’s climate and space weather. It is the hope that this discipline will start to be taught at universities worldwide and thus contribute to addressing the immediate need to develop the next generation of heliophysicists.

The session culminates with a lunch-time Town Hall Meeting. A limited number of box lunches, sponsored by the University Corporation for Atmospheric Research (UCAR), will be provided on a first come, first serve basis.
