The highest level of activity is expected to occur in the evening, and the best chance of seeing it will be from late at night until the next morning, when the radiant rises high in the sky. We can’t expect them to appear very often, but under good conditions, we can expect to see about 5 to 10 of them every hour.
What type of meteor shower? The number of meteors that can be expected
October 21 around 23:00 Eastern time (Tokyo)
・ Peak this year: October 21st (Monday) around 15:00

Orion is famous as a winter constellation with many bright stars that are easy to find. Thanks to this, the Orionid meteor shower is famous, but its activity is lower than the three main meteor showers.
This year’s main event is expected to occur around 3:00pm on the 21st (Monday), but in Japan, meteors will appear from around 10:00pm when the radiant point rises
in the sky until dawn on the 22nd (Tuesday).
This year, the bright, full moon will illuminate the night sky most of the night, creating poor conditions for meteor viewing. According to AstroArts, the number of falling meteors is expected to be around 5 to 10 per hour even in good conditions.
Meteors appear not only around the constellation Orion, but they can appear anywhere in the night sky, so try to look as widely as possible in the sky.
* Radiant point: a point on the celestial sphere from which shooting stars (meteoroids) appear to fly out.
This year, the Earth will be in the same position at midnight on the 14th (Sunday) around 11pm. Although the potential is not high, please keep an eye out for unexpected activity.
1. fast speed
The meteors of the Orionid meteor shower are characterized by their high speed, and bright meteors known as fireballs and meteors that leave traces known as meteor trails can appear.
2. The maximum level of activity is gradual
For several days before and after the peak day, the number of meteors that appear does not change much, so it can be said that the meteor shower has a gradual level of activity.
Although the center of the high pressure system will move to the east, it will be clear and we will be able to see the meteor shower mostly in Hokuriku, Tokai, and Kinki. Although there will be thin clouds high in the sky in northern Japan, you will likely see meteors.
As a front approach and a low pressure system from the west, it will be difficult to see in Kyushu due to cloudy weather and rain. There will be some cloudy weather in Chugoku and Shikoku.
Clouds can spread along the coasts of the Kanto and Tohoku regions, but the further inland you are, the better your chances of seeing it.
