Mercury's solar excursion
November 2006: Mercury provides observers with a rare treat this November.
A rare astronomical treat awaits observers November 8. Starting at approximately 2:12 P.M. EST (11:12 A.M. PST), Mercury's black disk begins a 5-hour trek across the Sun's face. The planet's leisurely pace allows plenty of time to appreciate solar system dynamics. And the transit provides a great opportunity to share your expertise and telescope with others.
