In 2017 the circumplanetary region of the directly imaged planet beta Pic b transited in front of the star. This created a rare opportunity to detect the ring system of an extrasolar giant planet with semi-major axis 10 au. The search for evidence of ring was conducted over many months using a host of space-based facilities and ground-based telescopes located on four continents, including Antarctica. This 3-day workshop in Nice, France, endeavors to share the status of various data sets, devise common analysis techniques, and produce self-consistent models and interpretation for publication in the peer-reviewed literature.
