According to the materials of the National Astronomical Observatory of Japan, the peak “maximum” of this year’s outbreak is after 4 am on the 13th. It is expected to be seen frequently over the three nights of 11th to 13th before and after that. It appears around 9 pm and increases as it approaches twilight (the sky before sunrise is faintly bright) after midnight. In Japan, the conditions are best near the dawn of the 13th, and in Tokyo at around 3:00 am, it seems that about 50 can be observed per hour in a dark place and about 5 in the city. How much you can actually observe depends on your skill level, eyesight, and of course, the weather conditions.
A meteor (shooting star) is a phenomenon in which when dust in outer space rushes into the Earth’s atmosphere and burns out, its components shine and draw streaks in the night sky. A lot of dust is left in the path of comets (Suisei = broom stars) in a band shape, and when the earth approaches there every year, it jumps into the atmosphere, causing a meteor shower with many meteors. The time when the earth passes through the Chilean belt and the meteor shower occurs is fixed every year. In the case of the Perseids meteor shower, the celestial body that left Chile is “Comet Swift-Tuttle”.
Of the meteor showers of 100 or more in size, those with frequent meteors are called “three major meteor showers”. Among them, the Perseids meteor shower is relatively stable and numerous every year. However, the maximum time and the favorable conditions of the moonlight overlap almost once every eight years, and the next best time is 2029.
Meteor showers can appear anywhere in the sky, but when they are traced back and extended, they gather at a single “radiant point.” This is because Chile is falling from outer space over there. The radiant point of the Perseids meteor shower is near the constellation Perseids. Over time, the higher the altitude of the radiant, the greater the number of meteors.
It is completely unpredictable when and where each meteor will appear in the sky. Observe with the naked eye in an open space as much as possible. It’s easier to lay a sheet and lie down, but you need to make sure it’s a safe place to use. To prevent infection with the new coronavirus infection (COVID-19), please refrain from going out and be careful to avoid close contact with others.
