Monday, November 11, 2019: Transit of Mercury
Mercury will pass directly between Earth and the Sun on November 11. Because Mercury is so small relative to the observed disk of the Sun, the transit is not visible with just a filter over the naked eyeappropriately filtered telescopes or binoculars are necessary for viewing. The transit will be visible from most of North America from 7:35 A.M. EST to 1:04 P.M. EST (4:35 A.M. PST to 10:04 A.M. PST; it will be in progress at sunrise in mid- to western North America).
