Partial lunar eclipse: where and when the longest phenomenon in almost 600 years can be seen

The longest partial lunar eclipse in almost 600 years will occur at dawn on Friday, November 19, and can be seen in almost all of Latin America and North America.

At the peak of the phenomenon, the Moon will have more than 97% of its surface covered by the shadow of the Earth and it will take on a reddish appearance.

Its duration, estimated at 3 hours and 28 minutes, will be The largest one that there has been in a partial lunar eclipse in the last 580 years.

Where will it be visible?

Eclipses like this occur when the Moon passes partially through the Earth’s shadow (penumbra) and only part of the satellite passes through the darkest shadow (umbra).

Depending on the magnitude of the eclipse, a dark red, rusty, or simply charcoal gray color may appear on the shaded part of the lunar surface.

In a lunar eclipse the Earth casts its shadow on the Moon.

The phenomenon of this Friday will be visible throughout the American continent, Northern Europe, East Asia, the Asia-Pacific region, and Australia.

Partial lunar eclipses occur more frequently than total eclipses, but this year’s will be unusually long.

The previous one took place in 2018 and lasted only one hour and 43 minutes, that is, about two hours less than was forecast for this Friday.

An early morning show

In the case of Latin America, the countries of the region will have the best opportunity to appreciate the phenomenon almost in its entirety.

But to do so, it is necessary to set an alarm clock, because the central part of the phenomenon will occur in the early hours of Friday (not the night).

The culminating point, when 97% of the Moon will be covered, will occur at 03:02 in CDMX, 04:02 in Bogotá and Lima, 05:02 in Caracas and 06:02 in Buenos Aires and Santiago de Chile.

As the moon sets on the horizon, and the first rays of the morning begin, the phenomenon could be blurred for the countries with the most advanced hours.

During a lunar eclipse, the Moon can turn reddish.

Weather conditions always play a role. If there are clouds, it is unlikely that you can see how the Moon turns reddish.

No special equipment is needed to look at it, since the phenomenon can be seen with the naked eye. But binoculars or a simple telescope offer a more detailed view.

The year 2021 will close with another total solar eclipse on December 4.

Although it is the most anticipated spectacle of its kind, since the Moon totally blocks the light of the Sun and generates darkness, it will be an eclipse visible in its entirety only in some remote areas, among others, Antarctica, the South Atlantic and the southern tip of Africa.
