The unique astronomical phenomenon — the longest total Eclipse of the moon in the twenty-first century, coinciding in time with the great opposition of Mars with the Sun, will occur on July 27, and it can be observed practically in all territory of Russia.

Mars will approach the Earth on the minimum distance, becomes brighter than Jupiter and will give way to Shine as the Sun, the moon and Venus. In the sky he will stand out a bright orange color. Following the great opposition of Mars will happen only on 15 September 2035.

The duration of the total lunar Eclipse will be three hours and 56 minutes (from 21:24 GMT to 01:20 GMT), and the total phase will last one hour and 43 minutes (from 22:30 GMT to 00:13 GMT).

«The phenomenon is well seen almost on the whole territory of Russia. During the full phase of the Moon completely enters the Earth’s shadow and gain a purple-red hue,» — noted astronomers of the Moscow planetarium.

As expected, the Moon will pass through the center of earth’s shadow. This will be the first Central lunar Eclipse since 15 June 2011. It occurs near apogee, when the moon disk is minimal, so the Eclipse will be the longest in the twenty-first century. In the extremely rare occurrence of Mars on the day of the Eclipse passes the point of the great opposition with the Sun. Both lights during the blackout will be located close to each other in the South-Eastern horizon.

Only in the XXI century will happen 225 lunar eclipses, 85 of which are full, and of these the full of only six with a duration of more than three and a half hours.

Where to watch in Russia

A total lunar Eclipse on 27 July — one of the most interesting and favourable for observations in the European part of Russia for several years. Despite the short summer night, the phenomenon will be visible from beginning to end, and only in the North-Western regions, the Moon will rise above the horizon in the initial phases of the Eclipse. The full phase will be visible in Western Siberia, and its beginning to lake Baikal.

In Russia it is best to observe this Eclipse in the North Caucasus, the Caspian depression and the southern Urals. There is the greatest phase of the Eclipse will occur near local midnight and will be visible at a height of more than 20 degrees above the horizon. In the Central regions of Russia the Moon will be visible at a lower altitude, say the astronomers of the Moscow planetarium.

Initial private phase of the Eclipse can be observed in the morning of 28 July, even in the far East of Russia. The Eclipse will not be visible only in the Northern part of Siberia.

Visibility in Moscow

In Moscow the full Moon rise over the southeastern horizon after 21:00 GMT, already starting to take in the penumbra of the Earth. An hour later at 22:00 Moscow time, there after it will appear bright red Mars. At the moment of maximum Eclipse, at 23:30 GMT, the Moon will be 14 degrees above the horizon and Mars will be visible in six to seven degrees below the moon at the southern horizon. Both lights will be located in the constellation of Capricorn, to be red in colour and probably similar in brightness, presenting a rare sight.

The celestial spectacle will be visible to the naked eye, but binoculars and a telescope you can distinguish the elements of the surface of both celestial bodies. The most important condition — clear, cloudless weather.

How will the Eclipse

20:15 Moscow time the Moon touches the earth’s penumbra, at this time will begin penumbral Eclipse. It is difficult to see with the naked eye, especially at small phase, but as you get closer to the edge of earth’s shadow darkening will become more noticeable. At 21:24 GMT the Moon is completely immersed in the earth’s penumbra touches the earth’s shadow — the beginning of the partial Eclipse; at that time already good will be seen darkening the Eastern lunar limb. The moon will begin immersion into the Earth’s shadow.

At 22:30 GMT the Moon is completely immersed in earth’s shadow, at this time will start complete Eclipse. Depending on atmospheric conditions and some other factors darkening of the lunar disk during a total Eclipse may be different from other full lunar eclipses. It can be very dark when the Moon is practically invisible in the night sky, and can be bright when the Moon is clearly visible even at full phase.

23:22 MSK is the maximum phase of a total Eclipse — the third disk of the moon will be below the center of the earth’s shadow; at this point, the Browning (redness) of our companions as possible. The moon will be in earth’s shadow more hours (103 minutes). At 00:13 GMT Moon begins to emerge from the shadows — the end of the full Eclipse and the beginning of its partial phases. Gradually becoming brighter, setminsize lunar disk will make phase similar to the phases of the moon throughout the month, but only to change they will be much faster.

At 01:19 GMT the Moon completely out of earth’s shadow — the end of the private phase and the beginning of the penumbral Eclipse. At 02:29 GMT the Moon completely exits the earth’s penumbra. The end of the Eclipse. Night star will Shine again in full force.

Where else can you see

The Eclipse on July 27 will be fully visible in East Africa and Central and South Asia, and Antarctica. In South America, West Africa and Europe, the Eclipse will begin at sunrise of the moon, East Asia and Australia — on the contrary, when entering. In North America the Eclipse will not be visible at all.

Upon the occurrence of a total Eclipse the Moon takes on a reddish or brownish tinge. The color of the Eclipse depends on the condition of the upper layers of earth’s atmosphere. Total lunar Eclipse 6 July 1982 had a reddish tint, 20-21 January 2000 — brown hue.

These are the colors the Moon takes on during an Eclipse because earth’s atmosphere scatters more red light, so can not observe the blue or green lunar Eclipse.
