Meteorite cluster activity peaks tonight Best time to view is from midnight to sunrise
On the 17th, the activity of the meteorite group in the constellation Shishi was maximized. The best time to see in Japan is from early morning until dawn on the 18th, when the seat is lifted. Why don’t you take action against the cold and look up at the night sky?
The activity of the group of meteors of the constellation Shishi is maximized from dawn until dawn on the 18th.
On the 17th, the activity of the meteorite group will be maximized. The maximum time is at 20:00 on the 17th, but at this time the point of radiation is below the horizon, and the best time to see it in Japan is from dawn to dawn on the 18th when the constellation rises. The activity seems slow, but it is not affected by the light of the moon, and in a place with good sky conditions, 5 to 10 can be seen per hour.
What is the climate in each area?
From the night of the 17th to the morning of the 18th, Hokkaido will be affected by the valley of pressure. The area around Honshu is expected to be covered in high pressure centered in eastern Japan.
Hokkaido will have many cloudy, snowy, or rainy places. However, there seems to be a place where the starry sky can be observed in a part of the Pacific Ocean side. There are many sunny places in Tohoku and Hokuriku, which are good conditions for starry sky observation. Clouds tend to spread in Kanto due to the influence of humid air, but there is a possibility that they can be observed through the gaps between the clouds. Tokai, Kinki, Chugoku and Shikoku will have many cloudy and rainy places. There are many sunny places in Kyushu and Okinawa, which have good conditions.
The observation of the starry sky is a measure against the cold
The area around Honshu is covered in warm air, and cold weather from the night of the 17th to the morning of the 18th is likely to be weak for this time of year. That said, the temperature at sunrise on the 18th is expected to be below 0 ° C on the Pacific side of Hokkaido in many places. In Tohoku there are many places where the temperature is below 5 ° C, mainly in the north, and in Hokuriku it is around 10 ° C. In the Kanto region, the temperature drops to about 5 ° C in the north and about 10 ° C in the south. Observing the starry sky requires robust measures against the cold.
On the other hand, in Kyushu, the temperature below 10 ° C will be limited to some areas of the interior. Okinawa is expected to have many places above 20 ℃.
