Super moon

A supermoon occurs when the full moon coincides with the closest approach to Earth in its orbit. Supermoons make the moon appear slightly brighter , larger, and closer to earth than normal.

Observation

Observing the supermoon is relatively simple since you don’t need filters to be able to observe it, in fact, you don’t need binoculars or telescopes either , because if the weather is clear and there are no clouds, you can easily observe it. It is important, yes, to find a place that is away from all light pollution so that it can be observed better.

Causes of the supermoon

It occurs when this natural satellite of the Earth is at a very close distance to the planet and also, the satellite is transiting the lunar phase called “Full Moon” . As the moon has an egg-shaped path, there is a section of that path that runs through this celestial body around the Earth, very close to the earth’s surface .

This approach more refulgent color Full Moon form this amazing event in which the Moon, besides having a 30% more brightness is almost 350 thousand kilometers from Earth. The conjunction of these two conditions is what makes the phenomenon a rare episode.

Effects edit

The supermoon does not have any kind of side effect contrary to what some astrologers say. It will also have no effect on the world or on nature . The supermoon can even be observed without the need for telescopes or binoculars.

Phases of the supermoon

• The moon enters the semi-darkness of the Earth : You must wait until the semi-darkness reaches 70 percent of the moon’s disk. For the first 40 minutes after the “start” of the eclipse, the full moon will shine normally.
• The shadow of the twilight begins to appear : the shadow is evident on the moon’s disk as the minutes pass and just before the moon enters the dark shadow of the Earth, the twilight will appear as a spot on the portion left of the moon.
• The moon enters the umbra of the Earth : A small shell appears at the left extremity of the moon. The partial phases of the eclipse begin; the pace quickens and the change is dramatic.
• 75 percent coverage : The colors in the umbra vary from one eclipse to another, red and gray are generally predominant , but sometimes brown, blue and other hues are found.
• Total eclipse begins : When the last part of the moon enters the umbra , the total eclipse begins. The brightness of this ring depends on global weather conditions and the amount of dust in the air.
• 6. Middle of totality : the moon shines dimmer and moves south of the center of the Earth’s umbra . Its upper part is darker, its lower part is brighter, with shades of reds, oranges and perhaps even a soft bluish-white color.
• Total extremes of the eclipse: the appearance of the moon begins from the threshold shadow .
• 75 percent coverage : there is no coloration within the umbra and the moon should appear black and featureless.
• The moon rises from the umbra: the dark central shadow erases the right hand limb of the moon.
• Penumbra shadow is fading and the eclipse ends.
• The moon comes out of the gloom and the eclipse “officially” ends .

Associated phenomena

There are some phenomena that are associated or related to the supermoon and among them we can mention:

lunar eclipse

A lunar eclipse is when the moon darkens when it passes through the shadow of the Earth. This event occurs when the moon , the sun, and the earth meet in a straight line and when the earth is right between the sun and the moon during this time. In such a scenario, the moon is in its full phase as it moves through Earth’s shadow.

blood Moon

A total lunar eclipse occurs when the Moon travels through the umbra of the Earth and blocks the light sun so it does not illuminate the surface of the moon. However, some of the sunlight still reaches the lunar surface indirectly, through Earth’s atmosphere , bathing the Moon in a reddish, yellow or orange glow . As the sun rays pass through the atmosphere, some colors in the spectrum of light filtered by a phenomenon called Rayleigh scattering. This is responsible for generating colorful sunrises and sunsets. The lengths of red wavelengths are less affected by this effect, so that the light that reaches the surface of the moon causing have a reddish hue , which makes the Moon completely eclipsed take a red color.

blue Moon

Blue moon is the name given to the second full moon that takes place in the same month, a situation that occurs from time to time. This situation occurs because the full moon occurs every 29.5 days , which is the time that a lunar month lasts. For this reason, if the full moon occurs during the first days of the month, there may be enough time in that same month for the moon to be full again.

When will the next supermoon be

If you did not manage to observe the last supermoon event that happened in the year 2017, you should not worry. In 2018 , two more events of this type are predicted and although one of them has already passed, the next supermoon will take place on Saturday , August 11, 2018 during the new moon and will happen at an approximate distance of 358,082 kilometers from the center. from the earth.

In addition, for the year 2019 , three different dates are predicted on which this phenomenon will be appreciated, on Monday, January 21 , on Tuesday , February 19 and finally on Saturday, September 28, 2019.
