| Session Description | The session provides a forum to discuss the response of the coupled Sun-Earth system to (1) extreme solar events, (2) extreme seismic events, (3) space environment effects on technology and climate, (4) phenomena at solar maxima, and (5) events at deep solar minima. Studies of extreme solar events themselves (coronal mass ejections, solar energetic particles, and solar neutrons ejection) are also the subjects of the session. Such events provide excellent opportunities to study the physical processes involved in the coupled Sun-Earth system. Recently improved data (from the bow shock to the inner magnetosphere regions) are made available from coordinated observations of multiple spacecraft. Extreme seismic events such as earth quakes and volcanoes provide the opportunity to understand upward coupling of the atmosphere, and explore the possibility of using the ionosphere as a precursor of earth quake. Space environment affects satellite systems, communication and navigation, power grids and Earth’s climate. The causes of upper atmospheric and ionospheric saturation at strong solar maxima are not fully understood. Deep extended solar minima provide opportunities to investigate the intrinsic behavior of the thermosphere-ionosphere-plasmasphere system, and its coupling to the regions below with minimum forcing from above. Papers addressing all these aspects of the coupled Sun-Earth system through observations, theory and modeling on global and regional scales are solicited. |
