MOON PHASES INDICATOR
Introduction
Moon phases indication allows the reproduction of the moon cycle (new moon, first quarter,
full moon, final quarter) by means of a disc or a window. The moon phases indicator offers
a representation of the sky in which the form of the moon is shown at its different stages
throughout the lunar month.
Reading
A disc, with two moons placed in a starry sky, turns in a window.
At the start of each moon phase, one of the two moons appears in the left-hand section of the
window; it initially appears as a slim crescent, emerging from behind the rounded edge, then
gradually grows over the course of the days.
In the middle of the lunar month, the moon appears in the middle of the window in its full form.
It then starts to gradually disappear behind the second rounded cover on the right.
