CEDAR email: 2024 AOGS Session ST-09: Space Weather in the Sun-Earth System

[Manu Varghese]

DearColleagues,

We cordially invite abstracts to thesession ST-09 entitled “Space Weather in the Sun-Earth System” at 21stAOGS 2024 meeting in Pyeongchang, Gangwon-do, South Korea during 23-28June 2024. Abstract submission deadline is on 2 January 2024.
Session description:
The space climate in the Sun-Earthsystem can be considered as the expected average behavior of the solar windand IMF, geomagnetic field, ionosphere, thermosphere and geomagneticallyinduced current (GIC). Space weather is the unexpected short-term changes inthe above phenomena. Space weather originates from the Sun as solar eruptions(coronal mass ejections – CMEs, and flares) and coronal holes. CMEs whileflowing through the interplanetary space become interplanetary CMEs (or ICMEs),producing large changes in the interplanetary space such as shocks and solarenergetic particle (SEP) events. The fast solar wind originating from coronalholes interact with the slow wind ahead, forming corotating interaction regions(CIRs).  The interaction of the ICMEs andCIRs with the Earth’s magnetosphere through magnetic reconnection leads towave-particle interactions, intense radiation belts, large currents in themagnetosphere and ionosphere, geomagnetic storms/activities, intense auroras,ionosphere-thermosphere storms, large geomagnetically induced currents (GICs),etc. Sometimes space weather becomes severe resulting in extensive societal andeconomic disturbances in the high-tech society by damaging satellite systems,electric power grids, rail-way traffic systems, oil and gas metal pipelines,etc. For example, if a space weather event similar to the 1859 Carrington eventoccurs at the present time, it can cause damages costing up to (estimated) 1-2trillion US Dollars. This session invites contributionson all aspects of space weather studies using ground- and space-basedobservations, theory and modelling.
