Eclipse of November 19, 2021 live: how to watch it online

a lunar eclipse, estimated by experts as the longest of the century, will occur between the night of Thursday 18 and the early hours of Friday November 19th, a phenomenon that can be seen online from a platform specially prepared to appreciate it in the best way.

According to the calculations of the specialists, this show will last for 3 hours, 28 minutes and 23 seconds, the shadow of our planet will cover 97.4 percent of the lunar surface.

It’s about a partial lunar eclipse which in astronomy is known as “frost eclipse”. As in this type of event, it can only be enjoyed in one part of the world. In fact, this time it will be visible in America, a large part of Europe and Oceania.

How to see the lunar eclipse live

a eclipse from Luna occurs when the Sol, the Earth and the satellite are visually aligned in the sky. It is then that a shadow cone is produced that darkens it while it is in its full phase.

According to NASA, there will be 228 lunar eclipses in the century. Photo: Shutterstock.

At that time, the Luna it crosses the shadow of our planet, which is divided into two parts: the central one is called the umbra, and the external one is known as the penumbra.

This time, there will be a partial eclipse exceptionally deep. There will be a thin strip of the moon exposed to the direct Sun at the peak of the phenomenon, so the rest of the Luna will take on the characteristic reddish tones of a lunar eclipse total.

The partial eclipses occur with a greater frequency than the totals, so they offer “more opportunities to witness small changes in our solar system that sometimes occur right in front of our eyes”, they assure from the NASA.

The entire event is visible from North America and the Pacific Ocean, Alaska, eastern Australia, New Zealand, and Japan. Of course, observers from Western Asia and Oceania will miss the first stages of the eclipse because they will occur before the departure of the Luna.

Similarly, South America and Western Europe experience the moonset before the eclipse ends. It will not be observable from Africa, the Middle East, or West Asia.

On Argentina, the start will be at 4:19, the peak, at 6:03; and will end at 9:04.

In Mexico City it will start at 1:19; the peak will be at 3:03; and will end at 6:04.

In Peru and Colombia the start will be at 2:19; the maximum will be seen at 4:03; and the end will be at 7:04.

In Spain it will start at 8:19; it will peak at 10:03; and will end at 13:04.

In Miami it will start at 3:19; it will have its maximum at 5:03; and will end at 8:04.

What is needed to see the eclipse

According to NASA, in the 21st century there will be 228 eclipses of Luna, of which only 57 (25%) will be partial. There will also be 86 penumbrals -not perceptible because the satellite only crosses the penumbra, the faintest area of ​​the earth’s shadow-, and 85 total ones, also known as “blood moons”, because in them the pearl-colored disk turns from a reddish hue due to the refraction effect.

In order to enjoy this incredible spectacle, you will not need to use special equipment such as binoculars, filters or telescopes since it can be seen with the naked eye.

If the weather is good and it is clear -a necessary condition-, the ideal is to try to see it from a place as high as possible and without light pollution.

The NASA will broadcast live on your channel YouTube this event that promises an average duration of three hours.
