During this period the moon reaches its last quarter phase on Thursday October 20th. At this time the moon will lie ninety degrees west of the sun and will rise near midnight local daylight time (LDT). This weekend the waning gibbous moon will rise during the early evening hours and will effectively ruin the late evening and early morning hours with intense moonlight. One could watch for meteors during the early evening hours between dusk and moonrise. Unfortunately at this time of night activity will be low. The estimated total hourly rates for evening observers this week is near two as seen from the northern hemisphere and one as seen from the southern hemisphere. For morning observers the estimated total hourly rates should be near eight as seen from mid-northern latitudes and six from mid-southern latitudes. The actual rates will also depend on factors such as personal light and motion perception, local weather conditions, alertness and experience in watching meteor activity. Rates are reduced during this period due to the intense moonlight.
The radiant (the area of the sky where meteors appear to shoot from) positions and rates listed below are exact for Saturday night/Sunday morning October 15/16. These positions do not change greatly day to day so the listed coordinates may be used during this entire period. Most star atlases (available at science stores and planetariums) will provide maps with grid lines of the celestial coordinates so that you may find out exactly where these positions are located in the sky. A planisphere or computer planetarium program is also useful in showing the sky at any time of night on any date of the year. Activity from each radiant is best seen when it is positioned highest in the sky, either due north or south along the meridian, depending on your latitude. It must be remembered that meteor activity is rarely seen at the radiant position. Rather they shoot outwards from the radiant so it is best to center your field of view so that the radiant lies at the edge and not the center. Viewing there will allow you to easily trace the path of each meteor back to the radiant (if it is a shower member) or in another direction if it is a sporadic. Meteor activity is not seen from radiants that are located below the horizon. The positions below are listed in a west to east manner in order of right ascension (celestial longitude). The positions listed first are located further west therefore are accessible earlier in the night while those listed further down the list rise later in the night.

A stream of meteors believed to be leftovers from Halley's Comet is expected to streak across the skies this week, but a full harvest moon will compete for attention and may obstruct some of the show.                                 登录/注册后可看大图 The meteors are called the Orionids because they appear to shoot from the second-brightest star in the Orion constellation, or from the hunter's elbow. On Oct. 20-22, observers in the Northern Hemisphere may see around 20 meteors per hour at maximum, while observers in the Southern Hemisphere may see around 40 meteors per hour. The radiant of the shower will be observed north of Betelgeuse, the brightest star in the constellation Orion, the Mighty Hunter. The annual show usually happens from Oct. 17 to Oct. 25, and this year it'll peak before dawn on Thursday. But that's also when a full moon will appear over North America, perhaps dimming the light of the meteors. So the best viewing times should be earlier in the week, when the moon isn't as bright. The best places from which to view the meteor shower are in locations with no light pollution.

出现在10月18~23日，极大一般发生在22日前后。猎户座流星雨是哈雷彗星带来的另一场流星雨，所以它与宝瓶座流星雨类似也有着速度很快，尾迹较长的特点。但是它的流星数目却不如宝瓶座流星雨多，一般为20，但是最近几年有增加的趋势。辐射点大约23时升起，后半夜观测条件不错。2011年月相已是残月，对观测也不会产生什么影响。

Orionids: October 21-22
The second meteor shower of the month peaks on the night of October 21-22, with the best activity between midnight and dawn’s early light. This major shooting star display is called the Orionids, for the meteors appear to radiate out of the sky just above Orion’s head and not far from his bright red super giant star Betelgeuse, which marks his right shoulder. These remnants of Halley’s Comet intercept the Earth’s orbit nearly head-on at 41.6 miles per second, so they quickly blaze across the sky.
Orion can easily be found. At 3:30 a.m. this giant of a constellation will be due south of your location and about halfway up above the horizon. A thin Waning Crescent Moon will be towards your east and will not affect observing conditions. Therefore, one could expect the typical hourly rate to peak at around 20 or so yellow and green meteors per hour. The Orionids are also noted for producing fireballs that create persistent dust trains high in the atmosphere.

What is it?  
The Orionids are a stream of meteors believed to be leftovers from Halley's Comet. The meteors are called the Orionids because they appear to shoot from the second-brightest star in the Orion constellation, or from the hunter's elbow.
On Oct. 20-22, observers in the Northern Hemisphere may see around 20 meteors per hour at maximum, while observers in the Southern Hemisphere may see around 40 meteors per hour.
Orionids  
Comet of Origin: 1P/Halley
Radiant: Just to the north of constellation Orion's bright star Betelgeuse
Active: Oct. 2-Nov. 7, 2011
Peak Activity: Oct. 21, 2011
Peak Activity Meteor Count: Approximately 25 meteors per hour
Meteor Velocity: 66 kilometers (41 miles) per second
Note: With the second-fastest entry velocity of the annual meteor showers, meteors from the Orionids produce yellow and green colors and have been known to produce an odd fireball from time to time.
Where should I look?  
The radiant of the shower will be observed north of Betelgeuse, the brightest star in the constellation Orion, the Mighty Hunter.  
Can I seen the shower if I live in a city?  
While the best place to watch is in a dark location you should be able some of the brighter meteors from the city. To find a good location you can check out our light pollution maps.  
Meteoroids are the debris sloughed off from comets. When they reach the Earth's atmosphere and burn up, they are referred to as meteors; otherwise known as shooting stars. Those that hold together and actually reach the Earth's surface are known as meteorites.
It was once calculated that the Comet Swift-Tuttle was on a collision course with Earth, suggesting that an impact was likely to occur in the year 2026. That theory was quickly debunked as recalculations of the nearly dual century data showed differently. The new theory is that in the year 3044, the Comet Swift-Tuttle will brush by within a million miles of the Earth, considering this future event to be a true 'cosmic near miss' by astronomers.

October 21, 22 - Orionids Meteor Shower. The Orionids is an average shower producing about 20 meteors per hour at their peak. This shower usually peaks on the 21st, but it is highly irregular. A good show could be experienced on any morning from October 20 - 24, and some meteors may be seen any time from October 17 - 25. The nearly last quarter moon may hide some of the faintest meteors this year. Best viewing will be to the east after midnight. Be sure to find a dark location far from city lights.

• Time is the averaged centre of the reported intervals in Universal Time (UTC);
• Solarlon is the astronomical position of the earth relative to the sun at the above time (equinox J2000.0);
• nINT is the number of reported intervals used;
• nORI is the number of Orionids observed in those intervals;
• ZHR is the Zenithal Hourly Rate, defined as (1 + sum nORI) / sum(Teff/C) where Teff is the effective observing time and C is the total correction coefficient for limiting magnitude, clouds and zenith correction 1/sin(hR);
• Particle density is the approximate number of particles (meteoroids) causing meteors brighter than magnitude +6.5 per billion cubic kilometer (i.e., a cube with 1000 km edge length). The ZHR depends on this density (which can be variable) and the velocity (which is roughly constant) of the meteoroid stream. For more information about the computation method, see the references at the bottom.

The rather wide waning crescent moon makes 2011 a so-so year for watching the Orionid meteor shower. But there’s a consolation prize. The moon will show you the red planet Mars on the peak nights of the Orionids!
Orionid meteors are debris from famous Comet Halley
Meteors first. The Orionid meteor shower will probably rain down the greatest number of meteors for 2011 before dawn on Friday, October 21, or Saturday, October 22. On moon-free nights in a dark country sky, the Orionids typically peak at around 10 to 15 meteors per hour. The moonlit glare may reduce the numbers somewhat this year. If you’re game, the time to look for these fast-streaking Orionid meteors is between midnight (1 a.m. daylight saving time) and dawn on Friday and Saturday mornings. The best viewing is usually in the wee hours before dawn. That time holds true no matter what time zone you’re in.
Rising time for the moon and Mars in your sky

Look eastward before dawn tomorrow for the planet Mars, the bright star Regulus and the constellation Leo the Lion

Now Mars near the moon. Mars looks like only a modestly bright ruddy star right now, and rises in the east during the wee hours after midnight. But Earth in its orbit is gaining on the red planet as we speak, so Mars will brighten in the months ahead. Mars will also rise earlier at night. By December 2011, you’ll see Mars climbing over the eastern horizon before midnight. In January 2012, it’ll be up by mid-evening, and even sooner on February 2012 evenings. By the time our planet Earth flies between this outer world and the sun in early March 2012, Mars will be out from dusk till dawn, shining some nine times brighter than it does at present.
Why is Mars sometimes bright and sometimes faint?
The chart at the top of this post shows the radiant point of the Orionid meteor shower. The shower’s radiant is in the northern part of the famous constellation Orion. If you do see some Orionid meteors tonight, and you trace their paths backward, you will find that they appear to radiate from this section of the sky.
You can find Orion fairly easily, even in the moonlit glare, because it’s the sky’s most distinctive constellation. Orion looks like a big rectangle, with its famous belt of three medium-bright stars marking the middle. These three stars of Orion’s Belt point downward to Sirius, the brightest star in the nighttime sky. Orion is up in the southeast around midnight now, and it’s high in the south before dawn. We’ll have much more to say about Orion in the months to come, because it’s definitely the showcase constellation of winter.
See Sirius, nighttime’s brightest star before dawn
Earth crosses the orbit of Halley’s Comet annually in October. Debris from this comet slams into the Earth’s upper atmosphere and vaporizes as its falls. The radiant shows you where orbits of the Earth and Comet Halley intersect. Before dawn on Friday and Saturday mornings will likely be the best time to look for these meteors, but the moonlit glare will probably somewhat obstruct this year’s Orionid meteor display. The moon and Mars, and the dazzling planet Jupiter — and Orion and Sirius — may be as much a highlight of the predawn sky as the Orionid meteors.

The object in the picture isn’t a meteor. It’s the most famous of all comets, Comet Halley, the parent of the Orionid meteor shower. Although moonlight will interfere, you might see some Orionid meteors tonight or especially before dawn tomorrow morning (October 22). The meteors look like streaks of light in the night sky. They’re sometimes called shooting stars.
Comet Halley – the Orionid’s parent object, pictured at the top of this post – last visited Earth in 1986. As the comet moves through space, it leaves debris in its wake that strikes Earth’s atmosphere most fully around October 20-22. Around this time every year, Earth is more or less intersecting the comet’s orbit.
The cometary debris left behind by Comet Halley — bits of ice, dust and rubble — create the Orionid meteor shower.
The annual Orionid meteor shower is expected to produce the greatest number of meteors before dawn on Friday morning, October 21, or on Saturday, October 22, 2011. As usual, the best time to watch this shower will be between the hours of midnight and dawn. Oftentimes, 10 to 15 meteors per hour can be seen on a dark, moonless night. However, the waning crescent moon will probably subdue the meteor count for the Orionids this year.

This isn’t the year’s richest meteor shower, or even the second-richest, but try watching this shower from midnight to dawn, when the most meteors will be flying. If you’re hankering to see some meteors, the moonlight makes 2011 a less than ideal year for the Orionids. But with the waning crescent moon showing you the planet Mars and the star Regulus in the glorious predawn sky, not all is lost. Moreover, the dazzling planet Jupiter will be blazing away in the west, plus the glorious constellation Orion will be beaming high in the southern sky. With all this thrown in the mix, the predawn hours are prime for watching the lore-laden skies and the Orionid meteors.

Orion meteor shower radiant in the constellation Orion

If the meteors originate in Comet Halley, why are they called the Orionids? The answer is that meteors in annual showers are named for the point in our sky from which they appear to radiate. The radiant point for the Orionids is in the direction of the constellation Orion the Hunter. Hence the name Orionids.
For me, even one meteor can be a thrill. But you might want to observe the 2011 Orionid meteor shower for an hour or more, and in that case the trick is to find a place to observe in the country. Bring along a blanket or lawn chair — after midnight or before dawn — and lie back comfortably while gazing upward. Watch debris from Halley’s Comet streak the predawn sky on October 22!

Halley Comet Meteor Show Due Next Week
Posted on 2011/10/18
If you watch between midnight and dawn on Friday, October 21, or Saturday, October 22, 2011, you should see some meteors in the Orionid meteor shower. Meteors are fancifully called shooting stars. They aren’t really stars. They’re space debris burning up in the Earth’s atmosphere. The Orionid meteors are debris left behind in the orbit of Comet Halley. The Orionids can best be described as a junior version of the famous Perseid meteor shower. The meteors are known as “Orionids” because the fireballs seem to fan out from a region to the north of Orion’s second brightest star, ruddy Betelgeuse.The Orionids typically produce around 20 to 25 meteors per hour under a clear, dark sky. Orionid meteors are normally dim and not well  seen from
urban locations. Orionid meteors will begin to increase noticeably around October 17, when they’ll start appearing at about five per hour. After peaking on the morning of October 22, activity will begin to slowly descend, dropping back to around five per hour around October 26. The last stragglers usually appear sometime in early to mid November.
