New Cometary Insights from the Close Approach of 46P/Wirtanen: A Symposium in Celebration of Mike A'Hearn

August 6-8, 2019

Edward St. John Learning & Teaching Center
University of Maryland, College Park, MD

This meeting is a celebration of Mike's work in cometary science, and his spirit will be reflected in the tone of the gathering. While the presentations will be primarily about comet science, there will be some non-scientists joining us and more are welcome. Our intention is to disseminate results from the Wirtanen Campaign but also to have fun in the process.


Oral sessions will be held Tue (Aug 6) morning and afternoon, Wed (Aug 7) morning, Thu (Aug 8) morning and afternoon. An excursion is scheduled for Wednesday afternoon.


Tony Farnham, Lori Feaga, Jessica Sunshine, Elizabeth Warner

... Days and Counting

2018-08-02 A few notices and reminders:

  1. We are still requesting pictures of Mike that we can show and distribute. If you have some that you are willing to share, you can upload them to our Google Drive [link:]
  2. If you are planning on going on the sailboat cruise in Annapolis as part of the Wednesday excursion, we wanted to let you know that you need to bring/wear soft-soled shoes when on the boat (e.g. no dress shoes). This is a dress code requirement from the ship's crew.
  3. We have enclosed a map showing the general layout of the area to help you get around the various meeting-related sites. There is also an interactive map on the meeting website that shows more details, including footpaths and trails.
  4. Parking validation codes have been sent out to those who signed up for them during registration. Note that these do not allow in/out capability (unless you can guarantee that you'll get the same parking spot when you get back). If you paid for parking and haven't received your code, then contact the registration desk to confirm that you signed up for it ( Parking is on the top (4th) floor of the Regent's Drive parking structure (see map). If you go down to the third floor, there is a bridge in the Southwest corner that exits in the direction of the St John's building.
