Do not miss ... "the blue dwarf" now decorating the skies of Egypt and the Arab world

The second full moon in the autumn season and the second full moon, which is called the blue moon, is now adorning the Egyptian sky, and the moon will arrive at the moment of the full moon today, Saturday October 31, 2020 at 05:49 pm (02:49 pm GMT) and it is at an angle of 180 degrees from the sun. A half orbit has been cut around the Earth during this month, which is the second full moon in the autumn season and the second full moon in one month in the Gregorian solar calendar, the so-called blue moon, which is an ideal opportunity for astronomical photography.

The Astronomical Society in Jeddah revealed in a report that this moon will also represent the second farthest and smallest moon of Badr – the dwarf moon – during October of this year, as it will be at a distance of 406,166 kilometers, which means that it is 49,131 kilometers away from the nearest and largest moon of this year – the giant moon – In last April, therefore, the size of the virtual apparatus will be about 14% smaller and less illumination by about 30% compared to the giant moon.

The blue dwarf moon oversaw the eastern horizon as the sun sets and reaches the highest point in the sky dome at midnight and sets at the sunrise the following day.

The description of the dwarf moon is given to the moon in the midst or the full moon when the distance between the center of the moon and the center of the earth is farther than 405,000 km. It is a term referring to the scientific name “apogee moon” and it means the moon’s location at the farthest point from the earth.

It is known that most months in the solar calendar contain only one moon, but during the month of October there are two, on October 1 and 31, and according to the general name, the second full moon is called the blue moon, which is just a name. The moon will not turn blue, but rather its usual gray color. Who watches every month.

In general, this blue dwarf will not have an effect on the Earth, except for the two phenomena of tides, which are normal, and it is known that the biggest difference between tides occurs at the full moon or its conjunction at the beginning of the month, and during these phases of the moon, the gravitational forces of the moon and the sun combine to draw ocean water in same direction? Since this full moon is at the farthest point from the Earth, the contrast is about 5 cm smaller than normal tides.

There will be no significant effect on the internal energy balance of our planet, because there are tides every day, so an unusual geological activity is not expected and there is no scientific evidence to support any such link.

This time of the lunar month is considered suitable for observing radioactive craters on the surface of the moon through binoculars or a small telescope, unlike the rest of the terrain that appears flat due to the fall of the entire moon in the sunlight, these radiating craters are deposits of bright reflective materials that extend from the center of the craters outwards for hundreds of kilometers It is believed that these craters are of recent formation and the “Tycho” crater is considered the most radiant crater.

During the coming nights, the moon will rise late by about an hour every day, and within a few days it will be seen only in the sky of dawn and early morning, and at that time it will reach the final square phase a week after it has fallen into the full moon phase.
