The 2016 transit of Mercury across the Sun will be visible throughout North America, Mexico, Central America, South America, and parts of Europe, Asia, and Africa. Viewers with telescopes and solar filters will be able to observe the dark disk of the planet Mercury moving across the face of the Sun. NASA's Solar Dynamics Observatory (SDO) will be providing a near-live feed of the SDO images of the transit at http://mercurytransit.gsfc.nasa.gov. Their images will be delayed a few minutes by the data delivery method, but the SDO website will display the data as self-updating movies. The movies will include a visible channel and most of the EUV wavelengths. You pick the box and wavelength and watch the transit unfold.
There are still a lot of mysteries associated with this planet - For more on Mercury, see my blogs from 2015: http://www.solarancestors.com/blog/mercury-the-suns-outpost
