The Romans said “Origo” to refer to the origin, so they used “orior” as a verb born. From there came “Ortus” for the birth of the sun, better known as dawn. “Ortho” in Spanish is defined as the exit of a star by the horizon. And this Sunday, With the lunar eclipsethe moon will have a beautiful ortho.
A total moon eclipse. Every year there are at least two lunar eclipses, but they are not always total. This Sunday, September 7, will be one of the longest in the decade, with a totality of 82 minutes visible from most Asia. It can also be seen already started From most of Spainwith the moon very low on the horizon. But it will not be visible from America.
A lunar eclipse occurs when the earth is aligned between the sun and the moon in full moon phase, and its shadow is projected on the lunar disc. The earth’s shadow has two zones: the gloom, which darkens the moon subtly, and the umbra, which blocks sunlight. In the case of a partial eclipse, the umbra looks like a bite, and in the case of a total eclipse, the full moon darkens.
A blood moon. During the totality phase, The moon can become redwhat is known as blood moon. Although the umbra blocks the sunlight, the Earth’s atmosphere refracts solar light filtered towards the satellite. In this case, the blue wavelengths are dispersed by a physical phenomenon known as Rayleight dispersion, hence the red tones predominate.
The blood moon this Sunday will reach its most intense point at 20:11. If you are in Spain, the moon will be totally eclipsed, reddish color. Even so, with a clear horizon, you can see the best part of the show, especially from the Balearic Islands and the Mediterranean coast of the Peninsula. On the other hand, visibility will be low to the west, particularly in the Canary Islands and Western Galicia, where only the partial phase of the end of the eclipse can be seen.
The full schedule of the eclipse. In the peninsular hour (UTC+2), the Moon will enter a gloom (slight darkening) on Sunday at 17:28. The partial phase of the eclipse (the bite) will begin to be seen at 18:27, but only in the countries where the moon is already out. The totality phase (the moon is completely inside the Umbra) will begin at 19:31 and will end at 20:53. Then the partial phase will be repeated until 21:56 and the Penumbral until 22:55.
What will be seen from Spain. The visible phases will depend on whether the moon is whether or not where you are. In Madrid, the Moon will leave at 20:35, so they can be seen about 18 minutes. In general, the moon will leave the horizon totally eclipsed and dyed red from most of the country, with the exception of western Galicia and Canary Islands, where only a partial eclipse will be seen.

Where you have to look. Unlike a solar eclipse, seeing a lunar eclipse is totally safe with the naked eye and with prismatic. Since in Spain it coincides with the exit of the moon, it will be best to look for a place with the horizon is clear (a beach of the coast, a viewpoint, a roof …) and wait for the satellite to rise, already eclipsed and red, for the sky.
