SpaceWeather finally posted the results of the Mercury Transit Photo Contest from a few weeks back, so I thought I would link to a few of my favorites.
From Thad V'Soske, Colorado National Monument, Colorado, USA Nov. 8. 32-frame transit photo animation represents the motion of Mercury from 12:12pm to 1:29pm (local time) on November 8, 2006.
From the Japanese Hinode Spacecraft, which used its Solar Optical Telescope to capture a 0.2-arcsecond resolution movie of Mercury transiting the sun. See also the X-ray Transit of Mercury.
A young astronomer named Ryan Dunn manned the Solar viewer and expertly explaining the details and dynamics of the transit to the public at the Albuquerque Astronomical Society event.
