2011 Pastorids, observation time of the Maherds

There is a possibility. (As mentioned on the first floor, the forecast of meteor showers is not very accurate so far) June 28 The June Shepherd meteor shower is extremely large.

A radiant between the constellations Pastoris, Hercules and Draconids, which is active from late June to early July each year, is known as the June Hercules meteor shower, or JBO for short.

In normal years, the flow of the June Shepherd meteor shower is not large, and the ZHR is below 20. In 1998, there was an outbreak of more than 100 ZHR and it lasted for about half a day. In 2004, the ZHR reached about 50 at its peak.

Is the mother comet of the June Shepherd meteor shower a 7p Pons? Comet Winnick, orbital period year, last returned to perihelion in September 2008. According to observations, the two eruptions in 1998 and 2004 were associated with dust clumps left behind by a 19th-century return of the parent comet.

There is a possibility of an outbreak of the Shepherd meteor shower in June this year, and it is expected that the maximum will occur at 5 o'clock Beijing time on June 28, and the optimistic estimate is that the ZHR may be around 100. For our observers, the observation conditions on the night of the 27th and 28th were good. In the region around 40°N, for example, the radiant is very close to the zenith shortly after dark, and observations throughout the night are not affected by the moonlight.

The only regret is that the June Shepherd meteor shower is very close to the summer solstice, and we only have about 5 hours of time for regular visual and photographic observations. You may not have seen it yet, but the sky is already bright.

If you are interested, you can choose an open place in the wilderness, wait patiently, and maybe good luck will befall you!

The above is an excerpt from the magazine "Astronomy Lovers", you can also check it out on the Star Friends Space Station**.

Meteor showers are not like celestial phenomena such as solar eclipses, which can only be seen in a small part of the area at a time. It can be seen halfway around the world. But so far, meteor showers cannot be accurately predicted.

Don't talk about the time. It's not even sure if it's going to come. I can only give an approximate date.

Like this Pastorid meteor shower, it's only known around June 27. However, there is one rule that remains the same: the best time to observe meteor showers is usually between the second half of the night and before dawn.

This is because of the rotation of the earth. In the second half of the night, we were facing the direction of the earth. So you will hit more meteoroids.

It's like running on a rainy day, and you'll get more raindrops on your chest than on your back. And in the first half of the night we were on the opposite side of the direction of the Earth's orbit. If a meteorite catches up from behind, there are obviously fewer chances of crashing.

However, if you haven't seen it, I advise you not to get your hopes up. What I actually see is not like fireworks like some **. Because it is said that there are dozens of them per hour, but most of them are not visible to the naked eye.

It would be nice to see a few "fire meteors" that really have a bit of flavor throughout the night. The vast majority of observers, who are not hardcore astronomy enthusiasts, read it overnight and have two words in their heads: fooled":

According to the landlord said [I want to go and see it after the high school entrance examination this year], I think the landlord will not ask about June 27, 2013, but about the Pastorid meteor shower on June 27, 2012, and the time has long passed. The Perseid meteor shower on August 12 has also passed.

The best places to observe meteor showers in Shanghai are: Chongming Dongtan, Nanhuizui, Fengxian Beach and other places far away from the city.

This year, let's look forward to the Draconid meteor shower on October 8, the return of the parent comet 21p, and there may be an outbreak (uncertain). In the event of an eruption, the recommended time for the average person in Shanghai and its surrounding areas is 18:30-22 o'clock on October 8 (after 22 o'clock, until the radiant points set around 02 o'clock, the number of meteors will gradually decrease).

On October 21 this year, the Orionid meteor shower is extremely large, zhr = 25 hours (not every minute) You don't need to watch it in downtown Shanghai.

On November 17 this year, the Leonid meteor shower was extremely large, and although the observation was completely undisturbed by the moonlight, the flow was very small, zhr=15 hours, and there was no need to see it in downtown Shanghai.

The Geminid meteor shower on the night of December 13-14 this year is extremely large (the observation is not disturbed by moonlight) zhr = 120 hours, which is worth ** Just be well prepared, especially from the cold.

Observation conditions] Generally speaking, considering the serious light damage in large cities, if you want to see meteor showers, the Geminid meteor shower on December 13 and the Perseid meteor shower on August 12 are the most recommended (the meteor showers we are familiar with are both periodic meteor showers, which occur every year). Even for these 2 major meteor showers, the farther away from the urban area is the better, and novices are likely to not see or only see a few in the urban area. Of course, other small cities should avoid city lights appropriately depending on the serious situation of light damage.

In any case, you have to go to a place where you can see a lot of stars, and for novices, you have to go to a place where you can see dense stars.

You can ask, I'll check the specific ** time for you.

The active period of the Muppids is from June 22 to July 2, so it is best to observe during this time, as the Mastorids are related to the comet "7P", the parent comet of the Mapuds. Comet 7p was first discovered in 1819 and orbits the Sun in 6.38 years. Rainy days with clear skies and high air quality are perfect for observation.

Due to the relatively large proportion of bright meteors in the meteor shower group, people can easily fly to the meteors, especially in the first half of the night, because the radiant is high and there is no moonlight interference, it is the best time to observe. You can choose to monitor in the suburbs with a wide field of vision. In the late spring and early summer, you can first find the Big Dipper, and then extend the three stars of the Big Dipper along the arc, and you can see a very bright star, which is the main star of the Pastoral constellation, Arcturus (Multurus Star), which is the brightest apex of the "Spring Triangle" in the starry sky on a spring night.

The constellation Pastorius is made up of several stars of medium brightness forming a pentagonal shape, like a large kite, and the brightest star in this constellation is a large arcturus (depending on the magnitude, like a light hanging under a kite). Alternatively, you can find Arcturus in the north and then look for it.

Of course, the June Pastids were very erratic, and between 1928 and 1997, there were almost no meteor showers for nearly 70 years. Therefore, whether it can be observed or not depends on luck.

The text that the friend upstairs is looking for should be correct, but I think it's also more misleading, right?

First, is this the only time that can be observed? It was daytime. Fortunately, the answer is no, and meteor showers are a time period. At peak is the time of the most traffic, and you can see the activity of meteor showers for a period of time before and after.

Second, is maximum time the best time to observe? The answer is most likely not. The number of meteors observed and the brightness of the sky (is the sun setting, is the moon rising?).

Radiant height, cloud occlusion and other factors. Generally speaking, peak time is by no means the best time to observe.

I don't want to say much about this Sheptid meteor shower, because the flow is so small that it's a dismissive level for me. Although there is ** hype that the traffic of its outbreak can be 100, but there is no expectation this year, then it is polite, the traffic is counted as about 10. In the night sky of the city, Qin Liang has more than 100 stars, and the harvest is about 1 in the first half of the night.

I don't know if this number appeals to landlords, but my advice is to take a break early. If you want to see it, wait for the Nanbao Vase on July 28, or the Yingxian on August 12. It would be irresponsible to hype up this meteor shower.

2013 Jun 27 17:12 is the most important moment of the Pastorid meteor shower.

Since the early morning of June 28, 2011, the Shepheids meteor shower has come to the earth, and the sky in Chengdu, which has just been baptized by rain, has clear sky and high air quality, which is very suitable for observation.

According to experts, around 5 a.m. on the 28th is the peak of the Maherds, and hundreds of meteors are expected to pass through the sky every hour.

At about 4 o'clock in the morning, the mist over Chengdu dissipated, and the sky was full of stars. At an observation point located in the southern suburbs of the city, the reporter found seven meteors passing by within 10 minutes through naked eye visual inspection.

According to expert estimates, the average velocity of this meteor shower is 14 kilometers per second, which is much slower than the average meteor shower meteor 50 kilometers per second and 70 kilometers per second, which is conducive to observation. It is understood that there are also many astronomy enthusiasts in Chengdu who drive to the outskirts of the city to observe. June 27, 2012 at 11 o'clock June Shepherd meteor shower maximum ZR80

There's plenty to see for astronomical observers in June. The reporter learned from the Guangdong Astronomical Society that the public could see the Jupiter conjunction the moon, the Lyrid meteor shower and the Mufurid meteor shower in the month.

After the sun sets on June 1 this year, the crescent moon and Jupiter are seen to be closer to each other, and they are the brightest objects in the evening sky. At around 3 a.m. on June 11, the Moon obscured Saturn, but the two can only be seen converging at close distances in our country. The best observation time in China is from 0:00 to 2:00 a.m. on the same day.

From June 11 to 21, the Lyrid meteor shower can be observed. Among them, at 6 o'clock on June 16, the Lyrid meteor shower is extremely large, and about 5 meteors can be seen per hour. The public can observe for two consecutive days from June 15 to 16, of which the moonlight observation in the first half of the night has less impact, and the observation of the moonlight in the second half of the night has a greater impact.

From June 22 to July 2, the Maherds can be observed. Among them, the Maherds are extremely large at 20 o'clock on June 27, and about 20 meteors can be witnessed per hour. This year's Pastoral meteor shower is not affected by moonlight and can be observed 60 minutes after sunset.
