IAU SYMPOSIUM 401: ADVANCING REFERENCE SYSTEMS, EPHEMERIS, AND STANDARDS
Dear Colleagues,
 
  It is our pleasure to announce that the International Astronomical Union
(IAU) Symposium
  "Advancing Reference Systems, Ephemeris, and Standards: from the Earth and
the Moon
  to Solar System Bodies" (IAUS 401) will be held from August 4 to 9, 2025,
at the National
  University of La Plata (UNLP), La Plata (Argentina).
   
  Reference systems and their standardization are of paramount importance to
many fields
  of astronomy. Some examples are the reduction of ground-based
observations, space
  astrometry, astrophysics missions, and space missions to solar system
planetary bodies
  and beyond. The concept of a reference system and its realization requires
the
  convergence of reference frames, ephemeris, and time scales to be
developed respecting
  associated standards, thus fulfilling one of the IAU strategic goals as
the provider of
  astronomical standards and their use.
  The IAUS 401 will provide a forum to discuss the latest results and
prospects in these
  fields and thus facilitate the coordination of common standards across
agencies and
  organizations.

The IAUS 401 is structured in six key topics:

/1.- Earth rotation models and Earth Orientation Parameters (EOP)/
  /2.- Celestial and terrestrial reference systems/frames/
  /3.- Reference systems/frames for the Moon and other solar system bodies/
  /4.- Time scales and time metrology/
  /5.- Ephemerides of solar system objects/
  /6.- Astronomical standards/

The IAUS 401 registration, abstract submission, and IAU travel grant
applications are
  already open. The symposium will be in a hybrid format to welcome
in-person and online
  participation.
  For additional information and contact details, please refer to IAUS 401

We are looking forward to seeing you in La Plata!
  Sincerely,

Alberto Escapa and Laura I. Fernández,
  On behalf of the SOC and the LOC
