Working Group on Solar Eclipses

The tasks of the International Astronomical Union’s Working Group on Solar Eclipses include:

a) Working with the general public, providing materials and links to explain why eclipses are interesting to watch, how to observe them safely, and what science is being studied; and
b) Working with professional astronomers from around the world, to help coordinate their expeditions to total solar eclipses, including helping them work with customs in various countries about the temporary importation of scientific equipment.
