Session Proposal: SOHO: Thirty Years of Solar and Heliospheric Science (AGU25)

SH024
SOHO: Thirty Years of Solar and Heliospheric Science

Session ID#: 251323

Session Description:
The Solar and Heliospheric Observatory (SOHO) was launched on 2nd December 1995 and in the subsequent thirty years the data collected have transformed the study of the Sun and the heliosphere. SOHO’s comprehensive suite of in-situ and remote sensing instruments have been observing heliophysical domains from the solar interior through to the solar wind at 1AU for almost three solar activity cycles. This session solicits contributions that highlight SOHO’s broad and continuing impact across multiple scientific disciplines, such as (but not limited to) helioseismology, dynamics and heating of the solar atmosphere, solar wind acceleration and propagation, solar energetic particles, coronal mass ejections, space weather, total solar irradiance, solar cycle studies, and cometary physics. Contributions that use SOHO data in conjunction with data from missions such as Solar Orbiter, Parker Solar Probe and other observatories are also solicited.
