TOTAL ECLIPSE OF THE SUN



Solar eclipse can occur only at the time of the new moon, that is, when the extension of the imaginary line that runs through the center of the Sun and the Moon touches or touches the surface of the Earth. This occurs when the Sun and the Moon have almost the same geocentric longitude. Further, the Moon should be near the ascending or descending node.



The map below shows the Earth zones affected by the event. The two blacks discs, flanked by the initials "P.C." and "U.C.", all indicate the two points on Earth concerned, respectively, the first and last of the twilight of the cone created by the contact of the Moon body. The moments are expressed in Universal Time.

The instant T.U. is the time kept on the Greenwich meridian instant of maximum eclipse.
   The size (or magnitude) represents the percentage of the lunar disk coverage of the umbra
   (Total eclipse or partial shade) or penumbral cone to the other. For automatic calculation and display of
   any eclipse visible from their city is sufficient to take and install the free ECLIPSE V6.90 programs
