The full moon is observed for zero month in the sky of the Arab world, towards the eastern horizon at sunset, on the first Thursday of October 2020, and at this time of the year it is called the “harvest moon”.
The term “harvest moon” has been used for several years, which is a popular name given to the full moon in the months of September and October, which are the months close to the autumn equinox. Moonrise time is also close to sunset time for several nights in a row at the time of the full moon phase in the northern half. To the globe.
And the “harvest moon” falls upon completion, and is at a 180 degree angle from the sun at 16:11 Cairo time (21:04 GMT), and has cut half a circle around the earth, and remains visible in the dome of the sky until sunset dawn Friday Sunday.
In general, according to the Astronomical Society of Jeddah, moons close to the time of the autumn equinox are distinctive, because the zodiacal circle (the apparent path of the sun, moon and planets) forms a narrow angle with the horizon at sunset.
It is known that every full moon rises with the time of sunset, and on average the moon rises the next day, about 50 minutes late, and this happens every day, but in September and October, the narrow corner of the astrological circle of the zodiac with the horizon causes the moon to rise earlier than average in Northern latitudes.
In the northern mid-latitudes, instead of rising 50 minutes late in the days after the full moon, the waning hump moon will rise only about 35 minutes late for several consecutive days, while in regions in more distant latitudes near the Arctic moon rises About 15 minutes late for several days.
This was considered important in antiquity for farmers harvesting their crops before the era of light-bulb tractors, as there was not a long period of darkness between sunset and moonrise for several days after the full moon. , meaning farmers were working in the fields and harvesting crops under Moonlight hence the name Harvest Moon.
This is the ideal time of the month to see the radiating craters on the moon’s surface, through binoculars or a small telescope, unlike the rest of the terrain which appears flat due to the entire moon falling in the sunlight.
