The Triennial Earth-Sun Summit (TESS), held 7-12 April 2024 in Dallas, TX at the Hilton Anatole, is a joint meeting of the Space Physics and Aeronomy Section of the American Geophysical Union and the Solar Physics Division (SPD) of the American Astronomical Society.

TESS welcomes participation by the entire Heliophysics community, including all four traditional sub-disciplines devoted to studies of the Sun, Heliosphere, Magnetosphere, and Ionosphere-Thermosphere-Mesosphere. TESS not only promotes greater interaction and unity within Heliophysics, but also connections to astrophysics and planetary physics.

Programming will kick off with a reception Sunday followed by the solar eclipse on 8 April; Dallas is in the path of totality. The eclipse day is followed by four days of scientific programming. The online program is now available.
