Can you see the Phoenix meteor shower in Shangrao (home)? What is the exact time? Can be seen with the naked eye

Please accept it if you are satisfied, thank you!

What's the name of the meteor group? Activity time? Good times? Maximum flow (ZHR)?

Phoenix meteor shower in July? July 9-17? July 65438, 2004

Phoenix meteor shower? 165438+1October 29th-65438+February 9th 65438+February 6th? 6 Sometimes 100?

Perseid meteor shower? From July 23rd to August 22nd, August12-13,90-130 (2016 is 150).

There are two meteor swarms with radiation spots in Phoenix. One is the Phoenix meteor shower in July, and the other is the Phoenix meteor shower in11-65438+February.

? IMO International Meteor Organization did not give the forecast of Phoenix meteor shower in July 20 16. The reason is obvious, because the maximum discharge of the Phoenix meteor shower in July is too small, less than 1, and the radiation point is south, so it cannot be observed in most parts of the northern hemisphere. So it is meaningless to ask whether the maximum occurs in the evening or in the morning.

Watch the Phoenix meteor shower again. According to the forecast of IMO International Meteor Organization, the Phoenix meteor shower in 20 16 occurred at 0: 00 on February 2, 65438 (that is, Beijing time was 65438+8: 00 UTC on February 2, and Beijing time was equal to 8 hours UTC). Meteor shower prediction is not necessarily accurate because of its great uncertainty. The radiant point of this meteor shower is located in the southern hemisphere. The horizon of China is very low and the flow is uncertain. Usually, the annual flow is basically zero, so observation is not recommended.

? Let's talk about the Perseid meteor shower in August. During 20 1 1-20 15 years, the activity was at a normal level, and the ZHR was about 100. Jupiter will cause a significant increase in the scale of meteor showers as high as ZHR= 150- 180 in 20 16 years. The traffic of 20 17 will also increase, and then the activity of 20 18 should be lower than usual. Perseid meteor shower is one of the three major meteor showers in the northern hemisphere (the other two are quadrant meteor shower around 65438+ 10/4 and Gemini meteor shower around 65438+February 14). There is a small outbreak this year, which can be observed in the northern hemisphere. Shangrao is definitely no problem. IMO International Meteor Organization's forecast is that there will be a great event from 9: 00 pm on August 12 to the early morning of 13, Beijing time. Because the moon phase of the day was the first winding, there was moonlight influence in the middle of the night, so 13 could be observed in the early morning. If it cannot be observed in the early hours of 13 due to weather, it can also be observed in the early hours of1,12, 14.

Meteor showers are seen with the naked eye. Visual observation of meteor shower plays an extremely important role in the field of meteor shower. Meteors can also be monitored by radio.

The International Meteor Organization predicts the Phoenix meteor shower in 20 16.

The following is the Chinese translation of the Phoenix meteor shower predicted by the International Meteor Organization 20 16:

Phoenix meteor shower (code: 254 PHO)

Activity time:165438+1October 28th–65438+February 9th; Maximum time: 65438+8: 00 on February 2nd (maximum meridian λ θ = 250.0 degrees);

ZHR (number of zenith meteors per hour) = variable, usually constant;

Radiation position: right ascension = 18 degrees, right latitude = -53 degrees;

Speed (V∞) = per second 18km (slow); Brightness index (R): 2.8 (dark).

Age: 3 years old

The Phoenicids meteor shower (PHO) is one of the small meteor swarms that occur regularly every year. The occurrence date is generally between165438+1October 28th and 65438+February 9th. The biggest cycle this year is 8: 00 on February 2, 65438. The flow rate is not fixed, sometimes it does not appear at all, but occasionally it will reach ZHR ~ 65438. The average brightness of meteors is not high, but because the new moon (165438+1October 29th) is not long, there is almost no moonlight influence, and the observation conditions are good. The average speed of this group of meteors is very slow, only about 18 km per second, so it is easy to identify.

Phoenix meteor shower broke out at 1956, which lasted for several hours. However, due to the bad weather in winter and the low brightness of meteors, there are not many observation reports of phoenix meteor showers. In recent years, the phoenix meteor shower has been almost completely silent. Some studies have pointed out that this group of meteor showers may be periodic, but more observation data are needed to confirm it.

Mikiya Sato, a Japanese meteor expert, predicted that the meteor shower might have significant activity at 20 14 12 1, but it seems that there is no observation record. French meteor expert Jérémie Vaubaillon predicted that the next major event would occur at 08: 00 on February 2, 20 19, with a small number of meteors.

Phoenix is a southern constellation, which is beneficial to observers in the southern hemisphere. For most parts of the northern hemisphere, the altitude of Phoenix is very low, which is also one of the reasons that affect the observation results.

Chinese translation of 20 16 phoenix meteor shower forecast by international meteor organization.

Perseid meteor shower (code: 254 PHO)

Activity time: July17–August 24th; Maximum time: August12,21:00-August 13, 1: 30 (maximum meridian λ θ =140.0-140./kloc

ZHR (zenith meteors per hour) =150;

Radiation position: right ascension = 48 degrees, declination = +58 degrees;

Speed (V∞) = 59 kilometers per second; Brightness index (R): 2.2 (bright).

Age: 6 months

In 1990s, because the parent comet/KOOC-0/09P/SWIFT-Tuttle passed the perihelion at/KOOC-0/992, the Perseid meteor shower was intense, accompanied by the highest maximum. The orbital period of comets is about 130 years. The most recent activity of the meteor shower, which was further enhanced on the premise of ordinary extreme value, was in 2007, and the corresponding maximum longitude was 139 .68 degrees, followed by 140 .55 degrees in 2008. According to the prediction model results of Finnish meteor expert Esco Laitinen and Russian meteor expert Mikhail maslov, the Earth orbit in 20 16 years is closer to the meteor dense dust cluster due to Jupiter perturbation. Therefore, the background ZHR may reach the level of 150- 160. 12 At 06: 34 on August, the earth will encounter an eruption after 1 and may produce a small meteor, and its ZHR may increase to about 10. At 07: 23, the earth will encounter a large particle eruption after four revolutions, which may produce a bright meteor. According to the prediction of Jeremie Bajlon, a French meteor expert, the earth will encounter the densest ejecta after two revolutions between 08: 00 and 65: 438+02 (λ ⊙ = 65: 438+039.49-65: 438+039.66). The recent IMO observation report (see WB PP 32–36) found that the traditional average time or generalized maximum time is between λ ⊙ ~ 139.8- 140.3, that is, 2065438+85438+02+65438.

After that, although the activity level is uncertain, once it happens, the increase of meteor rate will last for several hours during the possible peak period. Of course, neither the node crossing time nor the prediction given in the above box can guarantee what will happen at that time. August 10 is the first quarter moon, and the moon is located south of the ecliptic. The influence of moonlight is only in the first half of the night, and the moon sets after midnight. It is more powerful to observe the Perseid meteor shower in the middle and high latitudes of the northern hemisphere. The radiant point of the meteor shower rises from 22-23 local time and stays at high altitude all night. Assuming that one of these situations occurs, it is particularly beneficial to observe in Europe during the peak period of August 12, and it is best to observe in North America when the traditional maximum interval is close to August 13 node. Various forms of observation are possible, but most parts of the southern hemisphere are not suitable for viewing.
