On December 26, Weathernews announced the national weather trends on January 4, 2016, when the "Quadrans Muralis" peaked. There are many sunny hours on the Pacific side of eastern Japan such as Kanto and Tokai, and it seems that the starry sky can be seen.

■ What is the weather on January 4th?
From the 4th to the early morning of the 4th to the 5th, when the Quadrantids meteor shower appears, the pressure distribution will be winter in northern and eastern Japan, so the starry sky can be seen toward the Pacific Ocean such as the Kanto and Tokai regions, and there is a chance to find a meteor. On the other hand, from Hokuriku to the north, clouds tend to spread toward the Sea of Japan, making meteor observation difficult. In western Japan, the starry sky is often blocked by clouds due to the influence of low pressure systems and fronts that pass over the sea in the south, and it is likely that meteors will be searched through the gaps in the clouds.

■ What is "Quadrans Muralis"?
The "Quadrans Muralis" is one of the three major meteor showers along with the "Perseids" in August and the "Geminids" in December. It peaks every year at the beginning of the new year. The constellation "Quadrans Muralis" no longer exists, but it was named after the constellation "Quadrans Muralis".

The radiant point is near the boundary between "Boötes", where the 1st magnitude star Arctouse is located, and "Draco", which is located so as to surround Ursa Minor including the North Star.

The peak appearance in 2016 is around 17:00 on January 4th. The Quadrantids meteor shower tends to flow at once during peak hours and not so much at other times. In 2016, when the maximum time is in the evening, the observation conditions are not very good. At most this year, about 15 will appear in an hour.

The moon rises after midnight. The age of the moon is 23, which is thinner than the half moon, but the moonlight is still likely to adversely affect observations.
