Can the Lyra meteor shower be seen in the northern hemisphere in 2022?

Can the Lyra meteor shower be seen in the northern hemisphere in 2022? In April, the Lyra meteor shower appeared between April 14 and April 30. It belongs to medium-intensity meteor shower, and the maximum zenith flow per hour is about 18 under ideal conditions. Can the Lyra meteor shower be seen in the northern hemisphere in 2022?

Can the Lyra meteor shower be seen in the northern hemisphere in 2022? 1 Lyra meteor shower can be seen in the northern hemisphere.

The maximum time of Lyra meteor shower in 2022 will appear at 3: 00 on April 23rd, 2022, Beijing time. Ideally, the maximum zenith discharge per hour is about 15. The radiation point rose about 2 1 the day before yesterday, but with the radiation point rising, the first quarter moon rose around 0: 00 on the 23rd, which had a great impact on the visual and photographic observation in the second half of the night. The Lyra meteor shower in April is characterized by unstable activity period and the longest time. Although the number of meteor showers is small, fireballs occasionally appear.

Maximum occurrence time: 3: 00 on April 23, 2022.

Best viewing time: April 22, 60 minutes after sunset to before the moon rises.

Best viewing place: away from light pollution; Surrounded by open, no mountains and no buildings, you can observe.

Peak value of ZHR (zenith appearance rate per hour): about 15.

Lyra meteor shower also has the following characteristics:

First, the flow of Lyra meteor shower is not large;

Second, its maximum duration is short, only a few hours;

Third, its color is white, and there are many bright meteors.

Fourth, meteoroids are fast, about 49 km/s;

Fifth, the active period coincides with the season when sporadic meteors are less in the northern hemisphere, so it is relatively easy to distinguish meteors outside the group, which is suitable for primary astronomy enthusiasts to visually observe.

Can the Lyra meteor shower be seen in the northern hemisphere in 2022? The maximum time of Lyra meteor shower in 2022 will appear at 3: 00 Beijing time on April 23, 2022, and the maximum zenith flow per hour is about 15 under ideal conditions.

Lyra meteor shower active period

The Lyra meteor shower in April (00006 LYR) appears between April 14 and April 30. It is a moderate intensity meteor shower, its parent body is C/ 186 1 (Thatcher), and its period is 4 15. Its active period is from April 15 to April 29, and it reaches the maximum around April 22. In general, the maximum zenith flow per hour is about 18 in an ideal state.

How many meteors can you see?

During the Lyra meteor shower, if there is not much light pollution outside the city, about 10-20 Lyra meteors can be seen every hour. If you only plan to look around on your balcony, considering the bright lights of the city, the number of meteors you can see will be greatly reduced, and it is very likely that you can only see two or three meteors an hour.

Of course, the direction of meteor shower is notoriously unpredictable, and Lyra meteor shower is no exception. Greece 1922, Japan 1945 and the United States 1982, the Lyra meteor shower broke out, and the flow reached about 100 per hour. No one predicted that the meteor shower would break out tonight. But who knows? !

Lyra meteor shower is one of the oldest known meteor showers with a history of 2700 years, but it was not until181861g1(Thatcher) that the comet was discovered. The dust belt left by this comet led to the appearance of Lyra meteor.

On the beautiful west bank of the Milky Way, there is a well-known bright star Vega, which forms Lyra with some small stars around it. April 15 to 29 every year is the active period of meteor shower named after this constellation.

Compared with meteor showers such as Gemini and Perseus, the discharge of Lyra meteor shower is much smaller, and the maximum ZHR value (the number of meteors that can be seen per hour when the radiation point is directly above the head under ideal observation conditions) is above 18. Although the flow is not very large, there are occasionally bright fireballs.

Can the Lyra meteor shower be seen in the northern hemisphere in 2022? From the evening of April 22 to the morning of April 23, it is expected that there will be a big event at 3 am on April 23.

By then, as long as the sky is clear, China and even all parts of the northern hemisphere can witness the Lyra meteor shower.

In the mid-latitude region of the northern hemisphere, the radiation point will rise to the horizon shortly after dark and can be observed all night. The radiation point reaches the top of the head almost before dawn, which is very beneficial to observers in the northern hemisphere.

In sunny weather, friends who like meteor showers can observe the eastern sky from the evening of 22nd to the morning of 23rd.

The best observation time in the northern hemisphere is the night of April 22, when the zenith flow will reach the peak value of 15 to 20 per hour. Because meteors are very dazzling in the night sky, they can be seen by the naked eye (as long as the surrounding light is dim enough). Observers can use the application software with augmented reality navigation map function to navigate for themselves in the night sky. Then look around Vega, which seems to be the birthplace of Lyra meteor shower.
