The night of the fire moon: how the sky will be during the total eclipse

From today's 23:36 the Moon will go into a total eclipse – and noticeably orange – according to experts could become a better show than any firework display.

You can see it all over the country and in South America. On every hill, every camp lost in Argentina, in every desolate field there will be no better program than lying on the grass to see the sky. For one night, the protagonists will not be the belt of Orion, nor Osiris, nor the Three Marias. As in a magic show, those who look up will see the full moon disappear for a long time.

As expected, for hours you will see how the moon hides and changes color. It will not be a simple eclipse, where a shadow disk hides the moon, but suddenly you will see in the night a kind of orange spiral.

Scientists explain that this is because during these phenomena, the atmosphere refracts sunlight in the shadow cone that hides the Moon, and given the quality of this light ("corresponding to the wavelengths of red and orange", point of the Planetarium of Buenos Aires), what you see is a strange circumference like fire.

A review of what can be observed, step by step:

-At 23.36 the Moon will enter the darkness, the "outer shadow" that the Earth generates in relation to the sun. Although it is the beginning of the process, in this case still almost nothing is seen.

-As you entered on Monday, at 00.34 the Moon will enter the umbra. This is: the thick cone of shadow that forms on the surface of the earth. It is something like the fragment of outer space from which the sun can not be seen because the earth is in the middle.

"When the clock shows 1.41 on Monday, the moon will be in absolute shadow, covered with earth. It will be the beginning of the so-called Wholeness, the most impressive stage of the phenomenon according to Planetary experts. This step will last 1 hour and 2 minutes and your critical time will be 2.12. "During Wholeness the Moon will be dimly illuminated with a soft orange-red color," the observatory's web advances.

The Totality will end at 2:43 in the morning, when the Moon begins to emerge slowly from the umbra. The rest of the eclipse will be like watching the movie upside down: over the next 67 minutes, direct white and intense sunlight will once again bathe the lunar disk. The Moon will come out completely from the umbra to 3.50, marking the end of the most interesting part of the phenomenon.

What will happen next? Those who went to bed early will try to watch it on YouTube or Instagram or even on television. They will rotate images in the networks of men and women who will try to capture it for them. One thing is fundamental: on some occasions, such as tonight, it will be so important to have a telescope at hand. Or a magnifying glass, at least. When the cosmos gets dark, it is always good to look closely.

In Buenos Aires, a separate show

Those who are in town will have their own show. Is that the Galileo Planetarium Galilei organized a plan to make a vigil and enjoy the phenomenon.

In addition to special telescopes organized for the occasion, there will be a musical number of jazz and outdoor lectures. From 10.30 pm the public will be able to enter the place, in Sarmiento and Figueroa Alcorta, free of charge.

Before the astronomical show, there will be a musical. A pair of blues and composite jazz Juan Cuiñas (guitarist and singer) and Nahuel Castrillon (harmonic) will play until the eclipse.
