An edited image from the OSPaN telescope shows the relative size of Mercury compared to the sun.
An edited image from the USAF Optical Solar Patrol Network (OSPaN) telescope at NSF's National Solar Observatory, in Sunspot, N.M., depicts Mercury's (the black dot between the cross hairs) approximate relative size as it transits the sun on Nov. 8, 2006. Mercury will have an apparent size of about 1/200th the apparent diameter of the Sun. The image was made Nov. 1, 2006, and the position of "Mercury" on the solar disk does not correspond to the transit path. Transit images will be available at http://nsosp.nso.edu/data/latest_solar_images.html.
