For Mandie Adams, the total solar eclipse on Dec. 4 will be the 12th one she’s seen. It will also be the 12th for her teddy bear, Dinky Doo.
Seeing it won’t be easy. The eclipse will be visible only on a sliver of Earth in Antarctica, the South Orkney Islands and the surrounding ocean. Ms. Adams, a rental-property owner who lives in Southend-on-Sea, England, flew from London to Madrid to Buenos Aires to the town of Ushuaia on the southern tip of Argentina. From there, she will board a 15-day eclipse cruise, which sails through the notoriously turbulent Drake’s Passage, to see just under 2 minutes of total eclipse darkness—if there aren’t clouds.
