Can you see a meteor shower in Anshan, Liaoning Province on April 22, 2009? Please help me solve it tomorrow. Thank you.

On April 22nd, the Lyra meteor shower was extremely huge.

The important astronomical phenomena in this month are concentrated in the later period, among which the Lyra meteor shower has attracted much attention. Some meteor showers have a long flow, such as Gemini meteor shower. Most meteor showers only have a short peak flow, and then they will soon calm down. Lyra meteor shower belongs to this type. According to the previous observation data, the ZHR value of Lyra meteor shower (maximum zenith flow per hour) is between 14 and 23, which is not considered as a big meteor shower. However, in 1982, the meteor shower ZHR in the United States reached 90 degrees. There is a saying that this is due to the error caused by the fact that the Lyra meteor shower is too short for observers to capture. If we collect and analyze the observation data in the early 20 years, we will find that the flow of Lyra meteor shower is slowly rising, that is to say, it is gradually "increasing". Maybe one day, it will become a big and stable meteor shower.

The activity period of Lyra meteor shower begins in mid-April. At first, its radiation point was in Ursa major, and later it moved to Lyra. Until the 25th, its activities basically ended. The biggest forecast of Lyra meteor shower given by the International Meteor Organization this year will appear on 22nd 19 Beijing time. The best place to observe the Lyra meteor shower is in the high latitudes of the northern hemisphere, because there, the radiation point does not fall all year round. However, its observation conditions are not bad in the middle and low latitudes and near the equator. At the peak of the meteor shower, the radiant point will rise from the east after sunset. This year's Lyra meteor shower has the best observation conditions in the Far East and North America because it rises earlier as it gets closer to the eastern radiation point. For most parts of China, the radiation point will rise to a more suitable observation horizon around 23: 00 at night, which is also a good opportunity for the observation of Lyra meteor shower. The moon phase of the day belongs to the waning moon, which has little influence on meteor observation. As long as the radiation point is above the horizon, it is possible for us to observe the meteors of the meteor shower. Therefore, for meteor observation enthusiasts, the author still suggests starting monitoring at 20 o'clock on the evening of the 22nd, which is close to the forecast time. The speed of Lyra meteor shower is about 49 km/s and its color is white. Knowing this will help you distinguish whether a meteor is in a group or not.

On April 24th, the π meteor shower in Mawei was particularly large.

I remember last year we introduced the π meteor shower in Mawei and observed it. Due to the low horizon of the radiation point and the serious influence of moonlight that day, we didn't observe a meteor in this group.

The earliest observed ponytail π meteor shower started at 1972, and then the mother comet 26P/Grigg-Skjellerup returned to the perihelion at 1977 and 1982, and the meteor shower broke out once, with a ZHR of about 40. But since then, the meteor shower has been silent, and the annual ZHR is only about 10. Last March, the mother comet returned, but the meteor shower observation all over the world was unsuccessful, for the same reason as ours. However, all this will not affect your attempt to observe again this year.

In 2009, the peak of π meteor shower will appear at 0: 00 Beijing time on 24th. Because the radiation point is in the south, the observation conditions in the north of China are poor, and the south is ok, so the southern hemisphere will be its best observation point. The radiation point of the meteor shower is above the horizon about half a night local time. The moon phase has been a waning moon during this period of this year, which will not affect the observation. This group of meteors belongs to slow meteors, so you can pay special attention to them when observing.

As you can see, no accident, if the weather is fine. The maximum value is 10 in the afternoon, so the observation will start at 8 o'clock if you mind.
