How many important astronomical phenomena do you know in September 219?

There will be many wonders in the astronomical phenomena in September 219. There will be many active meteor showers in September, and there will also be astronomical phenomena that rush to the sun. In September, there will be astronomical theaters staged in turn. So, let's reveal the important astronomical phenomena in September 219 by constellation knowledge. Let's take a look!

Important astronomical phenomena in September p>219 forecast the night sky in September, with bright stars. In the east, the starry sky has risen slowly in autumn. After dark, the Pegasus quadrangle, the symbol of the autumn starry sky, appears in the eastern sky. Pegasus quadrilateral is composed of Virgo I, Virgo II, Cedar I and Cedar II of Andromeda. Although these four stars are all second-class bright stars, which are not as bright as the summer triangle, it is still easy to find them in the night sky because most of them are third-and fourth-class dark stars.

Four stars form the four vertices of a quadrilateral, and the vertex in the northeast is Andromeda's Cedar II. In the northeast of Cedar II, there is the farthest celestial body that can be seen with naked eyes on the earth-Andromeda galaxy M31, which is much larger than our Milky Way galaxy. Since M31 is located in the eastern sky after sunset and can be seen for most of the night, September is also one of the best times to shoot M31.

On September 1th, Neptune rushed to the sun, and after sunset, it rose from the eastern sky and was visible all night. However, because Neptune is far away from the sun and its brightness is low, it is only a small blue-green bright spot in small and medium-sized telescopes, and its ornamental value is relatively average.

in the west, the afterglow of the starry sky in spring still remains on the horizon. After dark, the iconic bright star of the spring sky-arcturus of the Patriarch can still be seen above the western horizon. Jupiter is located in the southwest sky, and the observation conditions are acceptable. September is also the last time to observe Jupiter in the city this year. After September, Jupiter will be located above the southwest horizon after sunset, and the horizon is very low, which is easily blocked by urban buildings.

In the south, after dark, Scorpio and Sagittarius appear near the meridian, and in summer, the Milky Way also crosses the zenith and reaches the highest position. Saturn is located in the southern sky, visible in the first half of the night, and the observation conditions are good.

In the north, the Big Dipper is about to sink into the horizon, and the horizon is very low, so it is difficult to observe in Dongguan, where there are many high-rise buildings, and it cannot be used to indicate the position of the North Pole star. Cassiopeia has risen and is located in the northeast sky after sunset, which can replace the Big Dipper as an indicator constellation for finding the North Star.

zenith, after dark, you can see the summer triangle appearing near the zenith. For ordinary people, this is a good time to observe the summer starry sky, because you don't need to stay up late to see the summer starry sky in the sky near the meridian with the best observation conditions. But for astrophotography fans, this means that many shooting targets in the starry sky in summer only have a half-night shooting window, and the shooting conditions are getting worse and worse.

Meteor shower in September, 219

On September 1st, Auriga meteor shower was extremely strong. This is a meteor shower with a short active period. Every year from August 28th to September 5th, we may observe meteors in its group. Around September 1, this meteor shower will usher in a great. According to historical records, this meteor shower lasts for a short time and occasionally erupts.

in p>1935, 1986, and 1994, the meteor shower had ZHR bursts of 3 to 4. In recent years, the monitoring of the Auriga meteor shower has just begun, so many previous eruptions may have been missed. For example, only three observers had previously recorded the outbreaks in 1986 and 1994.

The first predicted explosion was in 27, when many bright meteors appeared, and the ZHR reached about 13 within 2 minutes. The radio monitoring data at that time showed that a sub-maximum, mainly a dark meteor, appeared about an hour after this maximum, but it was not observed visually, which was probably related to the influence of the full moon at that time.

The Auriga meteor shower is not expected to break out in p>219. It is expected to occur at 22: on September 1st, Beijing time, and ZHR has only single digits. Because the flow is too small, it is not recommended for the general public to observe it. However, those days were moonless nights. I believe many fans will go out to watch the stars in those days, and the great time is just the time for everyone to watch the stars. You can also pay attention to this meteor shower while watching the stars.

The Perseid meteor shower in September 1th is extremely large. Although it is also a Perseid meteor shower, the discharge of the Perseid ε meteor shower in September is far less than that of the Perseid meteor shower active in mid-August. Its active period can last from September 5 to 21. This meteor shower is more suitable for observation in the northern hemisphere because of the high declination of the radiation point.

In normal years, the ZHR of the Perseid ε meteor shower in September is only about 5. On September 9, 28, it had an explosion dominated by bright meteors. In 213, the same small-scale outbreak appeared again, but the duration was very short. According to the analysis of the current situation, there will be no large-scale activities in this meteor shower until at least 24. Of course, even if it broke out before, its ZHR was only about 3.

According to the relevant forecast, the Perseid ε meteor shower in September this year is still relatively calm, and it is likely to appear at 7: on September 1th, Beijing time, and the sunrise on that day is a more suitable observation period. However, due to the small flow, it is not recommended for the general public to observe.
