The Futago meteor group is a group of meteorites known for its steady flow of many meteors each year, and this year it is not affected by moonlight, so it is a good condition for observation.
The peak activity this year is said to be around 10 o’clock on the 14th (Monday) Japanese time, so in Japan today the night of the 13th (Sunday) is an opportunity to observe.
On the other hand, on the Pacific side of western Japan and eastern Japan, it seems that there will be many places where the starry sky will spread out on a sunny day. However, in western Japan, clouds are expected to pick up on the Pacific side as midnight approaches.

Due to the large number of meteors that appear, the Futago meteor group is considered one of the “three major meteor groups” along with the Shibungi meteor group in January and the Perseus meteor group in August.
This year, on the 15th (Tuesday), the day after tomorrow, will be the new moon, so there will be no influence of the moonlight, and the conditions will be quite favorable for the observation of meteorites. If you observe it in a dark place in the sky, you are expected to see up to about 55 meteors per hour by the time the date changes to 14 (Monday). Also, a relatively large number of meteors can be expected tomorrow (Monday) night, and up to 20 meteors can appear per hour.
In Tokyo, the constellation Futago, which has a point of radiation, begins to rise in the sky around 6:00 p.m. and the meteors begin to flow. Shooting stars fly around the sky, so it is recommended to look up at the sky regardless of the point of radiation. Protect yourself from the cold and enjoy observing meteorites.
It can be said that it is a group of meteors with few impacts, where many meteors appear in a stable way every year.
In places with few obstacles, such as clouds and buildings, it seems that shooting stars can be seen just by looking at the night sky for about 10 minutes.
(2) Observation is possible almost overnight.
Shooting stars belonging to the meteor group flow from a point on the celestial sphere called the radiation point.
As the name suggests, the Futago constellation meteor group has a radiation point in the Futago constellation, which is in full bloom in winter, so the radiation point rises to the ground early in the evening. Therefore, it is possible to observe twin group meteors almost overnight during the active period.
(3) The number of meteors decreases at once after the maximum day.
The Futago group of meteors is characterized by a decrease in activity shortly after the peak.
The seasons have been slow this fall, but starting this week it is expected to turn cold like winter. Even in sunny areas, it can get very cold, so perfect protection from the cold is essential for meteor watching.
