CEDAR email: 2025 AOGS Session ST-12: Space Weather Links from Sun to Earth Including May and October 2024 Events

[Manu Varghese]

Dear Colleagues,

Wecordially invite abstracts to the session ST-12 entitled “Space Weather Links from Sun to Earth IncludingMay and October 2024 Events” at 22nd AOGS 2025 meeting in MarinaBay Sands, Singapore during 27 July-01 August 2025. Abstract submissiondeadline is on 18 February 2025.

Session description:

Thissession covers the unexpected large temporal changes in the Sun-Earth systemincluding the 10-11 May and 9-10 October 2024 events. Space weather originatesfrom the Sun as solar eruptions (solar flares, coronal mass ejections (CMEs)and high speed streams (HSS) from coronal holes). Solar flares affect theionosphere within nine minutes. CMEs, while flowing through the interplanetary(IP) space become interplanetary CMEs (ICMEs), produce shocks, solar energeticparticle (SEP) events, radio bursts, etc. HSS originating from coronal holesinteract with the slow wind ahead, forming corotating interaction regions(CIRs). The interaction of ICMEs and CIRs with the Earth’s magnetospherethrough magnetic reconnection leads to wave-particle interactions, intenseradiation belts, large currents in the magnetosphere (ring current andfield-aligned current) and ionosphere, geomagnetic storms/activities, intenseauroras, ionosphere-thermosphere storms, large geomagnetically induced currents(GICs), etc. Space weather sometimes result in adverse societal impact andeconomic losses 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, can cause damages costing up to (estimated) 1-2trillion US Dollars. This session invites contributions on all aspects of spaceweather studies using ground and space-based observations, theory and modellingincluding the recent severe space weather events that resulted in geomagneticstorms of historical proportions.
