We will be holding a symposium at the University of Maryland in College Park on August 6-8, 2019 in celebration of the contributions that Mike A'Hearn made to cometary science.

In Mike's honor, this symposium will focus on results from observations of comet 46P/Wirtanen (and other recent bright comets) to allow the compilation of individual studies into a comprehensive understanding of the comet.

We encourage cometary scientists of all types as well as anyone who knew and worked with Mike in any capacity to come and participate in this event and to reflect on his legacy.
