Dear colleagues,

The 2024 solar eclipse is around the corner, and with it, the Triennial Earth-Sun Summit (TESS) meeting will be held on April 7-12, 2024, in Dallas, TX, in the path of totality.

We are glad to invite you to submit your abstract to our session: Early Evolution and Characteristics of Heliospheric Large-Scale Structures (LSS). This session addresses the studies dealing with the evolution of LSS, such as CMEs and SIRs, using models, techniques, and observational analysis (remote sensing and in situ measurements). Presentations may focus on the LSS local and global appearances, properties, magnetic fields, particles, and composition of isolated or merged LSS at their multi-point observations in the inner heliosphere.

Don’t miss the opportunity to present your work and to view the total solar eclipse.  Abstract submission is open until Wednesday, 11 October 2023, 23:59 EDT at https://agu.confex.com/agu/TESS24/prelim.cgi/Session/197539. The session description is below for your reference.

We look forward to seeing you in TESS and in the Session!

Session: Early Evolution and Characteristics of Heliospheric Large-Scale Structures

Large-Scale Structures (LSSs) are the main drivers of multiple terrestrial space weather effects. To better understand their impending appearance, it is vital to track their variabilities once they are launched in the interplanetary medium. Recent space missions such as Parker Solar Probe, BepiColombo, and Solar Orbiter carry both remote and in situ observational instruments, and they allow us to observe these structures from ~0.1 au up to 1 au. This session aims to address studies that uncover LSS early evolution using models and observational analysis and connect their forthcoming evolving appearance to the earlier one.
