Here's the occultation path. The shadow cast by MU69 passes through South Africa, crosses the ocean, and then continues through Argentina and Chile. I'm part of the South Africa team: 25 of us are headed to Cape Town. From there we'll drive north, and set up a bunch of portable telescopes on a N-S line crossing the occultation path (that is, roughly spanning the width of the central yellow lines, around where the 'S' in South Africa is).
