Moon eclipse 2021: how to observe it, first photos – Linternaute.com

MOON ECLIPSE – This Friday morning, November 19, 2021, part of the terrestrial globe can observe a partial lunar eclipse in the sky, the longest since the 15th century. Here are the first photos.

[Mis à jour le 19 novembre 2021 à 10h50] The lunar eclipse of this Friday, November 19 may be only partial, it is the longest eclipse ever seen since February 18, 1440. With a total duration of 6 hours and 2 minutes, the phenomenon can be observed since this Friday morning at 7:02 am Paris time and its peak was expected at 10:02 am Paris time, with 99.1% of the lunar disk being in the shadow of the earth. Here are the firsts photos of the partially visible lunar eclipse, followed by the most beautiful eclipse photos from around the world:

Unfortunately, it is not visible from mainland France, because the sun is already up … Astronomy enthusiasts can follow the event at this address Youtube of the Time and Date website. The European Space Agency (ESA) is also broadcasting the event live on its web TV. The astronomical phenomenon, on the other hand, can be observed from North America, much of South America, Northeast Asia, Polynesia and eastern Australia, according to NASA.

This Friday, November 19, 2021, the Moon entered the penumbra of the Earth at 6:02 a.m. UTC universal time (7:02 a.m. for Paris time) and the partial lunar eclipse began to be visible. The peak takes place at 9h02 UTC (10:02 am for Paris time). This is when the Moon turns red, a phenomenon “relatively” easy to understand: As the Moon enters the Earth’s shadow during the lunar eclipse, it takes for a certain period of time. of time a red tint. At this moment, the rays of the sun which have the longest wavelength (the red one), always reach the Moon. They are the ones who give it that coppery hue. The phenomenon is similar to that of sunsets, during which the sky also takes on a reddish hue. TO 12:03 UTC (1:03 p.m. Paris time), the Moon will emerge from the semi-darkness.

The partial lunar eclipse is a phenomenon that occurs when the Earth moves between the Moon and the Sun without these three stars being completely aligned.

It is important to emphasize that the astronomical phenomenon of the lunar eclipse is only possible when the moon is full. A lunar eclipse can only take place when the moon is at theopposite of the Sun with respect to the Earth and that it is therefore in the phase of full moon.

The next total lunar eclipse visible in France will not occur until May 16, 2022. As for the stars, this summer you absolutely must not miss the Perseids and their shower of shooting stars during the now famous Night of stars.

This phenomenon only occurs during total eclipses. As the Moon moves forward into the Earth’s shadow, the Moon takes on a red tint, which is known as the Blood Moon phenomenon. “The rays of longer wavelength (the red) continue to reach the Moon and give it a coppery hue. It is this same phenomenon which gives its color to the sunsets”, explains France 3 Region. The moon’s red color varies depending on atmospheric conditions, ranging from orange to bright red.

If the sky is clear, there is no problem to observe a lunar eclipse with the naked eye, without any danger (unlike thesolar eclipse) and without special equipment. We advise you to position yourself in the direction of the clear horizon. As with the Super Moon, in case you find yourself in an area where clouds obscure its visibility, you can arm yourself with your telescope, of yours binoculars or a pair of astronomical glasses to better observe the lunar eclipse.

For those who wish to immortalize the phenomenon, you can equip yourself with a standard 50mm lens as well as with longer focal length lenses (between 200mm and 2700mm on a full frame sensor). The important thing is to be able to have a tripod to avoid motion blur. The use of a telephoto lens is obviously ideal so that the moon fits completely into the frame, but for photographers with a small focal length, you can make an eclipse trail (successive overprints of the different phases of the eclipse on the same photograph). Given the low light during the lunar eclipse, set your device with a medium to high sensitivity depending on the phase of the eclipse, as well as a large aperture.
