Solar Eclipse of the Sun November 13, 2012

On November 13, 2012 will be a total solar eclipse that will be observable from South America, South Pacific, Northern Australia and New Zealand. This astronomical phenomenon will start at 19:50 GMT and will end at 23:00 GMT. Also from South America as seen from 22:20 GMT.

The following picture shows the places from which you can observe. 

The black dot marks the sites where the eclipse will be total, the lunar disk completely clog the Sun, while the shadow indicates the places where it will be partial.

How to safely observe a solar eclipse

The safest way to watch an eclipse is by projection old technique. Take a piece of cardboard and make a small hole in the center. Pointing at the Sun cardboard that light passes through the small hole and has to project on a flat white surface.

Be especially careful with the glasses for solar observations that are sold in stores, because not all are certified to ensure that they are treated with appropriate filters to prevent eye damage.

To avoid the risk of irreversible damage to the eye:
Do not look at the sun directly with the naked eye
Do not look at the sun with telescopes or other optical devices that do not have adequate filters
