Total lunar eclipse to be visible from Asia, Africa, Australasia, and Eastern Europe.

A total Lunar Eclipse will occur on Sunday 7 September 2025, starting at 4.27 pm GMT. It will be visible across the entirety of Australia, Indonesia, Asia apart from areas of the Russian Far East, the Indian Ocean, and the eastern half of Africa. In Eastern Europe, much of Central and West Africa, New Zealand, Melanesia, and Micronesia, part of the eclipse will be visible, although in these areas the Moon will either rise part way through the eclipse, or set before it is complete in these areas.

The Moon produces no light of its own, but 'shines' with reflected light from the Sun. Thus at Full Moon the Moon is on the opposite side of the Earth to the Sun, and its illuminated side is turned towards us, but at New Moon the Moon is between the Earth and the Sun, so that its illuminated side is turned away from us.

Lunar eclipses occur when the Moon passes through the Earth's shadow. This can only happen at Full Moon (unlike Solar Eclipses, which happen only when the Moon passes between the Earth and the Sum, and therefore only occur at New Moon), but does not happen every Lunar Month as the Sun, Moon and Earth are not in a perfect, unwavering line, but rather both the Earth and the Moon wobble slightly as they orbit their parent bodies, rising above and sinking bellow the plane of the ecliptic (the plane upon which they would all be in line every month).
