What is an Annular Solar Eclipse?
An annular solar eclipse happens when the Moon covers the Sun's center,
leaving the Sun's visible outer edges to form a “ring of fire”
orannulus around the Moon.
Annular solar eclipses have a “ring of fire”.
In an annular eclipse of the Sun, the Moon casts its antumbra - the outer part of the Moon's umbra - on the Earth.
Like total solar
eclipses, annular solar eclipses can be seen as partial eclipses from
locations inside its penumbra, but outside it's antumbra.
Annular solar eclipses take place only when the Moon is a new
Moon.
The Moon is at or near a lunar node.The Earth, Moon and Sun are
perfectly aligned in a straight line.The Moon is at its apogee.
Not Every New Moon Night
Even though a new
Moon is necessary for an annular solar eclipse to take place, we don't
see an eclipse every night there is a new Moon.
This is because the plane of the Moon's orbital path around the Earth is inclined at an angle of 5° to the Earth's orbital plane around the Sun – the ecliptic. The points where the two orbital planes meet are called lunar nodes. Solar eclipses occur only when a new Moon takes place near a lunar node.
