The sky of the Arab world attends, at midnight on Monday, December 21 and before sunrise on Tuesday, December 22, the arrival of the Debiyat meteors at their peak in conjunction with the winter solstice, and is considered the last rain. meteors of this year 2020.
Engineer Majed Abu Zahira, head of the Jeddah Astronomical Society, said the “Dabiyat” small meteors are active every year from December 17 to 25 as they cross the globe through dusty debris scattered along from the orbit of the comet (Total), where these dusty remnants hit the top of the atmosphere, so the planet’s atmosphere burns at an altitude of about 70 to 100 kilometers and appears to us as a brilliant trail of light .
Abu Zahira added, via the association’s official “Facebook” page, that in general, bears produce around 10 meteors per hour, provided the surveillance is done from a completely dark place away from city lights. and not from the house, and this year it will not affect his watch, because he will be in the first square phase and he will settle down just after midnight.
He continued: To try and see some, the northern horizon is watched towards the Ursa Minor cluster of stars, where meteors appear to radiate outward from in front of this star constellation, but meteors can appear from anywhere in the dome of the sky.
It should be noted that Al-Dabiyat meteors were newly detected only about 100 years ago, compared to the rest of the annual meteor showers, when it was noticed that some meteors are active at this time of l year and that they are not random. in their direction through the dome of the sky, but seem to rush from a point near the star of the North Pole In the grip of the constellation Dipper Minor.
