The lunar eclipse of July 27, 2018 was the second and last lunar eclipse of 2018 , after the lunar eclipse of January 31, 2018, and the longest lunar eclipse of the 21st century.
During the six-hour passage through the Earth's shadow, the moon moved almost centrally through the Earth's umbra, and the blood moon therefore became particularly dark. The total lasted just under an hour and 43 minutes.
This lunar eclipse is the 38th lunar eclipse of the 129th Saros cycle .
visibility
The entire course of the total lunar eclipse could be observed in East Africa , in South and Central Asia as well as in the Indian Ocean and Antarctica . It was observed in South America , West Africa and Europe during the rising of the moon and in East Asia and Australia during the moonset .

Europe
In Europe, the penetration was in the penumbra not observed (time P1 = start Penumbralität) because the moon only after the penetration into the umbra opened (time = U1 beginning of partiality) in the southeast. At most European observation sites, it was only visible during totality (after time U2) because only then was it sufficiently high above the horizon. The maximum of the eclipse took place at 10:22 p.m. ( CEST = UTC + 2 hours). The entire process of leaving the Earth's shadow could be observed from 11:13 p.m. (CEST). At the moonset the moon was already visible again as a full moon .

Simultaneous Mars opposition
At the same time as the lunar eclipse, when the moon is in opposition to the sun, Mars, six degrees below the moon, was in opposition to the sun. Thus it was in line with the earth-moon system and had a particularly small distance to the earth, as it will only appear again after about 20 years.
Mars therefore currently has a large apparent magnitude of almost -3 magnitudes. Although it did not appear as bright as the unshaded full moon before and after the eclipse, it was clearly brighter than the blood moon during totality. Even in binoculars or in the telephoto lens it was not only recognizable as a glowing red point, but also as a small disc. Its apparent diameter (about 24 arc seconds ) was about 70 times smaller than the moon (about 29.5 arc minutes ).
Such a constellation with simultaneous opposition to the moon and Mars only occurs every 25,000 years.
