Anonymous users2024-02-06Because the number of meteors is not only related to the flow, but also related to the height of the radiant, after the radiant rises at 22 o'clock, the flow may gradually decrease, but the elevation angle of the radiant gradually increases, as for the change in the number of meteors, it is difficult to say. The accuracy of the forecast for meteor showers is not very high, and it is entirely possible to be at peak for a few hours, so I am afraid that the exact time cannot be given for this question.

Major meteor shower DAO in 2008
On March 3, the Quadrantids were in the radiant (60,200).
It can be seen all night, and it is enough to observe the sky when there is no moon.
May 22nd. Lyrid meteor shower (20, 90).
Aquariids on the 6th of the month (50).
May 12 Perseid meteor shower (80).
The radiant will be visible overnight and can be observed at the zenith when there is no moon.
On the 13th of the month, the radiant of the Geminid meteor shower (120) will be visible all night, and there will be some meteor showers to watch from the zenith when there is no moon.
The Taurid meteor shower in early October (many fire meteors).

Anonymous users2024-01-311. Location and time of meteor showers in 2021.
1. According to the forecast of the International Meteor Organization (IMO), there will be more than 30 meteor showers this year.
2. The most worthwhile meteor shower:
Quadrant meteor shower on January 3.
May 6 Aquariid meteor shower.
When the Perseid meteor shower is at its peak (August 13), the moonlight has no effect on the radiant that rises in the second half of the night.
When the Geminid meteor shower is at its maximum (December 14), the moon phase is between the first quarter and the full moon, and only a few hours after the moon until dawn are better for observation.
3. Meteor shower time throughout the year.
January 3, 2021 23:00 Quadrantid meteor shower maximum (ZHR 120).
April 22, 2021 20:00 Lyrid meteor shower maximum (ZHR 18).
May 5, 2021 09:00 Aquariids Meteor shower maximum (ZHR 40).
July 28, 2021 at 11 a.m. Southern δ Aquariids (ZHR 16).
August 13, 2021 at 3 a.m. Perseid meteor shower maximum (ZHR 100).
October 10, 2021 20:00 Southern meteor shower maximum period (ZHR 5).
October 21, 2021 at 7:00 p.m. Orionid meteor shower maximum (ZHR 20).
November 12, 2021 at 7:00 p.m. Northern Taurid meteor shower maximum (ZHR 5).
November 18, 2021 02:00 Meteor shower maximum (ZHR 15).
December 14, 2021 at 3:00 p.m. Meteor shower maximum (ZHR 120).
December 22, 2021 at 11:00 p.m. Ursid meteor shower maximum (ZHR 10).
The radiant position shifts slightly when observed away from the maximum date, as shown in the International Meteor Organization's star chart. The maximum time of each meteor shower is Beijing time. Due to the uncertainty of meteor shower forecasting, if the maximum time listed is accurate to the day, the actual forecast accuracy is not higher than 1 day; If it is accurate to the hour, the actual accuracy is not higher than 2 hours; If it is accurate to 10 minutes, the actual accuracy is not higher than 15 minutes.
2.v is the velocity at which the meteor shower members crash into the Earth's atmosphere, measured in kilometers per second, without taking into account the Earth's gravitational pull. r is the quantitative index of the meteor shower, defined as the multiplier increase in the number of meteors for each dimming magnitude.
Smaller r indicates a larger proportion of bright meteors, and vice versa. The r of the same meteor shower may vary at different times, and the values in this table are for reference only. Ideally, if ZHR is the ultimate magnitude equal, the in-field occlusion rate is 0, and the radiant is always at the zenith, the number of meteors visible per hour is visually observed.
Due to the limitation of observation conditions, in most cases, the number of meteors visible in actual observations is less than ZHR.

Anonymous users2024-01-29Meteor showers are usually more likely to occur between 2:15 a.m. and 4:45 a.m.
A meteor shower is an astronomical phenomenon in which many meteors are emitted from a so-called radiant in the sky in the night sky. These meteors are fragments of the universe known as meteoroids that are projected into the Earth's atmosphere at extremely high speeds as they orbit in parallel orbits.
Features of meteor showers:
Most meteoroids are smaller than gravel, so almost all meteoroids are destroyed in the atmosphere and do not hit the Earth's surface; Debris that is capable of hitting the Earth's surface is called a meteorite.
Meteor showers that are particularly large or unusual in number are known as "meteor outbursts" or "meteor storms" and can produce more than 1,000 meteors per hour. Before sunrise on October 21-22, 2018, the Orionid meteor shower will reach its maximum.

Anonymous users2024-01-28Meteor showers are there all the time, it's just that you can't see your location or distance.
The Leonid meteor shower is held from November 14th to 21st every year, especially around November 17th, and some meteors burst out from the direction of the constellation Leo, which is about a little north-east and a horizontal altitude of about 40 degrees in the sky, which is the Leonid meteor shower. Therefore, the exact date is difficult to determine, as meteor showers can be seen during this time, but the clarity of the sight is different. It is mainly affected by factors such as the rotation of the earth, solar activity, and local climatic conditions.
