Should happen Quadrilaterals The first major meteor showers in 2021, the peak of its fall in the skies of the Arab world from midnight on Sunday January 3, after its radiating point rose after midnight and during the hours before sunrise Sun Monday, January 4 in the phenomenon of visualization with the naked eye without the need to use special monitoring devices.
Quadrilaterals produce around 120 meteors per hour, but this maximum rate is calculated assuming the sky is completely dark and its radiating point is at the top of the sky so in practice any actual sighting may not meet ideal conditions, and therefore The meteor count will likely be less than this, especially since the moon will be in the final square phase, coinciding with the tetrapod peak, which will cause faint meteors to mask most meteors.
In general, it is possible to see up to 45 meteors per hour after midnight or less from a dark location away from city lights, and they are expected to be in their best condition shortly before dawn. , when their radiation is at its maximum. highest altitude in the sky.
The point of radiation or launch of tetrapod meteors is near the constellation Ursa Major and the bright star ichthyosis spears at the northern end of the constellation Howl on the northern horizon, but the observer does You don’t need to determine the radiation point of meteors as they appear from anywhere in the sky.

Annual meteor showers are created as they pass Earth During its orbit around the sun through dense gatherings of dust and gravel scattered along the orbits of comets and asteroids, they collide with the top of Earth’s atmosphere and burn at an altitude of between 70 and 100 km and appear to us as a strip of light and this leads to meteor showers which are repeated on an annual basis.
Meteors associated with particular showers radiate from a common point in the sky, so that the showers can be easily distinguished from others because their paths appear to radiate or emit from a common point in the sky, and this is because the pebble particles in a given cluster move in roughly the same direction as they pass through Earth’s orbit., because there are very similar orbits to the object of origin from which it originates and hits the Earth in roughly the same direction and at the same speed.
The source of the quaternary meteors is mysterious. In 2003, it was determined that its main source is asteroid 2003 EH1, and if it was, then tetrahedra like Geminid meteors, coming from a rocky body – not an icy comet, it is believed that 2003 EH1 is the same comet C / 1490 Y1, which has been observed for 500 years, so the exact story behind the Rubaiyat source remains somewhat cloudy.
