At 5.29 am it will start to turn red. But already at 5.54 the sunset will be below the horizon in the South-West and the instant of maximum obscuration at 6.11 will not be possible to observe.
Thetotal eclipse of the Moon on Monday 16 May. It will be necessary to get up very early. The phase of penumbra begins at 3.32, the partial eclipse at 4.27, thetotal blackout of our satellite occurs at 5.29 am when the Moon begins to assume the red coloring typical of total eclipses. But it will not last long: at 5.54 in fact the Moon will set below the horizon to the South-West and the instant of maximum obscuration, at 6.11, cannot be observed. Since the Moon will be very low, just above the horizon, to see the eclipse at its best you will therefore have to be in an elevated place or in an area free of constructions. The phenomenon can be followed from 3.32 am live with the Virtual Telescope Projectwith images from Rome and the Americas, in a moment of supermoonthat is, when in its orbit the Moon is closer to the Earth than the average, and therefore its apparent diameter is larger.
The nodes of the Moon
The eclipse of the Moon occurs when the Earth is located between the Sun and our satellite, in a phase of full moon. The three celestial bodies must be aligned. Since the plane of the orbit of the Moon forms an angle of just over 5 degrees with that of the Earth, in order to have a total eclipse, the Moon must pass at the point of intersection of its orbital plane with that of the Earth (called plane of the ecliptic). The points of intersection, called knotsthere are two: one ascending (when the Moon passes above the ecliptic) and one descending (when it passes below the ecliptic). Eclipses therefore only occur when the Moon is in one of the two nodes.
L’eclipse of the Sun occurs only when the satellite is in a new Moon phase, that is when the Moon is interposed between the Earth and the Sun. In this case the rays of our star completely illuminate only the opposite side of the Moon with respect to the one we observe from the Earth, which therefore does not dark as it is commonly said, but the hemisphere that we cannot see because the Moon (due to the fact that the period of rotation on its axis is equal to that of the revolution around the Earth) always has the same hemisphere facing us. In the’eclipse of the Moonthis enters the cone the shadow of the Earth and takes on a reddish color (often referred to as Red Moon or, with a little exaggeration, of Blood moon) which depends on the diffusion and refraction of sunlight in the earth’s atmosphere that hits the lunar disk.
