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.
This year, the peak activity is said to be around 10 o’clock on the 14th (Monday), so in Japan the night of the 13th (Sunday) is an opportunity to observe.

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.
Since the 15th (Tuesday) is the new moon this year, it will not be affected by moonlight and will be a very favorable condition for observing meteorites. If you observe it in a dark place in the sky, you are expected to see up to 55 meteors per hour by the time the date changes to the 14th (Monday). Furthermore, a relatively large number of meteors can be expected on the night of Saturday the 12th and Monday the 14th, 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 meteorites 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, like clouds and buildings, it seems that you can easily see shooting stars just by looking at the night sky for about 10 minutes.
(2) Observation is possible almost overnight.
Shooting stars that belong to the group of meteorites 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. For this reason, it is possible to observe meteors in the twin group 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.
There is a high possibility that it will snow or rain on the side of the Sea of Japan, and it is very likely that observing meteors will be difficult. On the other hand, on the Pacific side of western and eastern Japan, it may be okay if the pressure distribution is winter-like.
The seasons have been slow this fall, but from mid-December it is expected to turn cold like winter all at once. Even in sunny areas, it can get very cold, so perfect protection against the cold is essential for meteor watching.
