Mercury will Transit the Sun on November 11th 2019.  We will set up an easel and do a solar projection of the event to share as a public outreach at the very busy BWI Airport Observation Park.

This park is normally packed all day and used by many bicyclists as a start and finish point, as there is a bike trail which is part of the Baltimore and Annapolis Trail, and also part of the Appalachian Trail that goes all of the way around the airport.  Mercury is roughly 1/200th the angular diameter of the Sun. 

I do not have solar filters for my telescopes, but have a lot of experience doing solar projections.  I constructed a new whiteboard easel for this event and will project the Sun's image and then use the projection to teach visitors about the Sun, and about the transit.
