The tip of South Africa, Tasmania and most of New Zealand will -- weather permitting -- enjoy a partial eclipse of the Sun on Friday although the handful of hardy scientists in Antarctica will get the best view, according to astronomers.
Partial eclipses occur when a fraction of the Moon obscures the Sun, and to those in its shadow a "bite" seems to have been taken out of the solar face.
The longest duration of Friday's eclipse will be at 0621 GMT, at a point east of the Antarctic peninsula.
It will be the last of four partial solar eclipses this year. The previous ones occurred on January 4, June 1 and July 1.
The last Sun-Moon-Earth alignment in 2011 occurs on December 10, with a total lunar eclipse visible from Europe, East Africa, Asia, Australia, the Pacific and North America, according to veteran NASA expert Fred Espenak.
