Jeddah – harmony:
The president of the Jeddah Astronomical Society announced that most of Saudi Arabia would witness a partial eclipse of the moon before sunrise on Monday, July 15, Jumada Al-Awal 1440 corresponding to the January 21, 2019 (according to the Umm Al-Qura calendar), with the exception of the eastern region and the southern part of the kingdom which constitutes the first eclipse of this year.
In general, the lunar eclipse is essentially a "total eclipse" that covers all phases of the globe in North America, South America, the Eastern Pacific, the Western Atlantic, Western Europe and in West Africa. Partly Central and East Africa and Asia.
The lunar eclipse rate will vary in the Saudi regions, where the northern regions will have the highest rate of alienation in the abandoned part of the lunar disk and this ratio will decrease towards the central and southern part of the lunar disk. kingdom.
(95%), Dibba (84%), Al-Qurayyat (87%), Al-Qurayyat (87%), Riyadh (1% (67%), Sakka (62%), Doma Al-Jandal (64%) and Al-Jala (67%) (43%), Dahban (41%), Hail (41%), Rafha (35%), Cradle (48%), (20%), Tarba (20%), Afif (19%), Oneeza (19%), Al Qunfudah (19%), (11%), Al-Qaysumah (11%), Al-Namas (11%), Al-Da & Admi (11%) ,), Barak (11%), Tenomah (10%) and Bisha (11%) (6%), Khamis Mushayt (6%), Jizan (4%), Dharma (9%), Hawara Sudair (8%) , Abha (7%). 2%), the culprit (1%) and Dai al-Dawasir (1%).
For the rest of the Arab world, the eclipse will be partially visible in Kuwait, Iraq, Jordan, central and eastern Syria, and eastern and central Sudan. No partial eclipses will be observed in the United Arab Emirates, Oman, Bahrain, Somalia, Djibouti, Comoros and Yemen.
While the eclipse will be seen entirely in Morocco, Mauritania, Tunisia, Algeria, Libya, Egypt, Far West Sudan, Western Syria, Lebanon and Palestine.
The total eclipse of the moon will be marked by the fact that the moon is at the closest distance from the Earth, or the so-called "giant moon", where the size and the light of the moon will be larger than most other moons.
Another feature of this eclipse is that observers from central and eastern Libya, Egypt, Western Syria, Palestine and Lebanon will be able to see a view very rare, where the sun is watched during its sunrise and where the moon is completely dissolved at the same time above the horizon and where celestial geometry and can not occur.
When the eclipse occurs, the sun and the moon are completely separated by 180 degrees in the sky. It is therefore impossible to see them together in the sky, but this happens because of the atmosphere around the globe.
What will be observed is an image of the sun and an image of the moon appearing above the horizon by refraction, which allows observers on Earth to see the sun briefly before it gets up and up. the moon after its real gravity. On the observer's site, provided that the eastern horizon and the western horizon are exposed away from buildings or mountains in a flat place such as the earth and the sky is clear.
The partial eclipse will begin at the same time in all regions of Saudi Arabia and the Arab world at 6:33 am (3:33 GMT), as the moon begins to penetrate the earth and begin to gradually lose its illumination. from the top left for the observatory.
During the partial eclipse phase, the shadow of the Earth falling on the Moon is so arched that the ancients realized that the Earth was spherical.
The entire lunar disc will fall under the ground and the total eclipse will begin at 7:41 am in Saudi Arabia (4:41 GMT). The total eclipse phase is important because of the way it occurs and the effect of the formation of the Earth's atmosphere.
If there is no atmosphere around the Earth, the moon will be black during the total eclipse phase, but it will be red. The reason is that the indirect light can reach the Moon, but before that, it crosses the Earth's atmosphere, which is scattered and most of the spectrum. The blue and the red spectrum remaining, in addition to the atmosphere, allow to capture a quantity of sunlight and to bend towards the moon to make it shine.
It should be noted that during the first minutes of the beginning of the total eclipse, the appearance of a color (bluish green) on one of the edges of the moon and that she prefers to use a telescope or a small telescope to see it because sunlight crossing the stratosphere enters the ozone layer absorbing the red light and passing over the blue light reaches the moon, and will be repeated in the first twilight after the end of the day. total eclipse in the Maghreb countries.
At 8:12 am in Saudi Arabia (5:12 GMT), the total eclipse reaches its peak and the moon sinks deep into the earth. The moon can be dark brown, red, bright orange or yellow depending on the amount of dust and clouds in the atmosphere. Air on the ground, followed by the arrival of the moon at full moon at 8:16 (5:16 GMT).
The total eclipse will end at 8:43 am in Saudi Arabia (5h43 GMT) with the start of the moon's release from the Earth and the second phase of the partial eclipse that will end at 9:50 am (6:50 GMT) Moonlight returns and ends with the main event.
Unlike the solar eclipse, the lunar eclipse does not require special monitoring device. She is very safe and presents no danger if she is seen with the naked eye. For better vision, use a small telescope or telescope where the results will be useful.
It should be noted that this lunar eclipse occurs two weeks after a partial eclipse of the sun on January 6, 2019 and that it will be followed in the second half of this year of the second solar eclipse of the twenty-nine of the month of Shawwal 1440 corresponding to the second of July and will not be seen in the sky of the Arab world.
