Lunar Eclipse 2018

3Shares

The second total lunar eclipse to happen in 2018 on 27th July. This time, the total eclipse of the Moon will be visible from Western Africa, and Central Asia, seen rising over South America, Eastern Africa, and Europe, and setting over Eastern Asia, and Australia. 

During this eclipse, the full Moon will go through the Earth’s shadow (or umbra) lasting around 6 hours and 14 minutes from start to finish. This is a very deep eclipse that lasts longer than the previous eclipse earlier in the year because the Moon passes through the central line of the Umbra.This expands the length of both the total phase and the eclipse overall. The illustration below shows how the Moon pass through the Earth’s shadow almost completely centrally. This could mean the eclipse will seem darker amid totality.

The Moon will slowly turn its natural silvery white shading to a reddish colour then back to its original colour all over a period of around five hours.The shade of red can change from eclipse to obscure contingent upon a couple of components incorporating conditions in the Earth’s upper air and the position of the Moon along its orbit.


If there have been any significant volcanic eruptions for example, this can cause the eclipsed Moon to show up a substantially darker red than of different eclipses. The additional measure of volcanic slag and tidy in the Earth’s air can piece a greater amount of the Sun’s light from refracting around the Earth amid the overshadowing causing deep, dark red effects.

Lunar Eclipse

The total lunar eclipse on 28 September, 2015, (shot at the highest point of this page), was considered especially dim and this was not simply down to volcanic ejections or air contamination. The 2015 eclipse was amid a perigee Moon when the Moon is nearest to the Earth (authoring the expression ‘Supermoon Eclipse’ at the time). This implied the Moon was more profound in to the Earth’s umbral shadow.

The obscuration on 27th July is the inverse and will happen amid an apogee Moon, however the eclipse will be a more profound one. That being stated, it’s difficult to predict with conviction how red the Eclipse on July 27, 2018 will be. It’s best to wait and see and enjoy any surprises that this eclipse may reveal.
