When was the first meteor shower in 2023?

As one of the three major meteor showers in the northern hemisphere, quadrant meteor shower is the first important astronomical phenomenon in 2023.

This is the bright fireball in the quadrant meteor shower shot by Tianjin astronomy enthusiast Liu Yuan in Jizhou District, Tianjin on June 4, 2022.

Constellation is an ancient name of constellation, which was founded by French astronomer Lalander in 1795. 1928, when the international astronomical union confirmed 88 modern constellations, it cancelled them and merged them into Draco, Shepherd and Pentecost.

But the name quadrant has been preserved in another way, that is, meteor shower. The radiant point of quadrant meteor shower is located in the adjacent areas of Dragon, Shepherd and Five Immortals, in the direction of bucket handle of the Big Dipper.

Yang Jing, a member of the Chinese Astronomical Society and director of the Tianjin Astronomical Society, said that the quadrant meteor shower has moderate speed and high brightness, and there will be very bright fireballs. The fireball will emit brighter light, and the meteor trail is longer and more lasting than ordinary meteors, which is very ornamental.

How the meteor shower is formed;

The formation of meteor shower is due to the debris split by comets forming a meteor group, which is attracted by the gravity of the earth, enters the earth's atmosphere, and rubs and burns with the atmosphere, forming a strange meteor shower landscape.
