Perseid Meteor Shower Peaks August 12th, 2009
by Kevin Brown : last updated: August 13, 2009Welcome back!
Every year in early August, we can observe the Perseid meteor shower (“the Perseids”). And it’s a fascinating sky event.
Here’s a beginners’ guide to what it is and how best to enjoy it. (Perhaps, impress your friends with these astronomy questions and answers!)
What are the Perseids and what is a meteor?
Every year in August, the Earth passes through rock and dust fragments left behind by the comet Swift-Tuttle, last time it came near the Sun. As these small particles collide with the Earth’s atmosphere, they burn-up, often creating a startling streak of light across the sky.
You can easily observe this and it can be a wonderous spectacle.
Why is it called the Perseid meteor shower?
The term “Perseid”, refers to the star constellation of Perseus.

The meteors actually have nothing to do with the stars we see from Earth, as being part of Perseus. It just appears as though the meteors originate from Perseus.
In fact, the rock fragments are close to the Earth – that’s why they burn in our atmosphere.
They are very close, just a few hundred miles – not many, many light years distant like the stars.
But, if you trace-back the bright trails of meteors we see, they appear to originate from the stars of Perseus.
When can you see them?
The Perseid meteor shower actually starts in late July and runs to late August. However, the best time to view is around the peak.
It’s not precise, but the 2009 peak is expected on August 12th at around 15.00 hours UT. There is some uncertainty, so it’s very worthwhile to observe either side of this.
In particular for European observers, the hours of darkness either side the peak hours, may well prove more fruitful! So try the previous Tuesday night, as well as the night of Wednesday 12th.
And there is also a potentially prominent Moon to contend with. It will not set below the horizon until the early hours of the morning.
What equipment do you need to observe the meteor shower?
The good news is none! Just use your eyes.
It will help your observation if you give your eyes some time (say 15 minutes), to become adapted to the darkness.
Binoculars my also help, but on the other hand, they may restrict your view to a small part of the sky.
The meteors originate in the region of Perseus, but they may appear in view just about anywhere in the sky. Although, if you were to track-back their trails, you would get to Perseus.
Can they be measured, at all?
Yes. Keen astronomers count how many appear in a fixed period of time, in a certain area of the sky. This is expressed as a Zenithal Hourly Rate (ZHR).
We may expect around 100 streaks of meteor light across the sky per hour, at or near the shower peak.
Do watch out for them on Wednesday 12th August and during hours of darkness, before and after.
Hi, im in northern ireland… will i b able to see them and if so, what time?
estoy en COLOMBIA aqui aun no ha anochesido pero quiesiera saber si aqui puedo ver la lluvia de meteoros y cual es el mejor momento para verlos????

Hi
I think we saw a few on friday 14th at 10 pm from heavitree, to the west, fairly low and agaist cloud.they werent going fast buy seemed to quickly burn up.no tails seen.
Hi will we be able to see it in South Africa?
[...] best views of the peak of the meteor shower last night were in remote rural spots in the south-east of [...]
will we see anything tonight in south east london
Are there going to be any comets/meteors tonight ?? If so what time??
Roger, There might be, but we are well after the activity peak now and activity will be tailing (!) off. Take a look when it’s dark and clear at your location. Best.
Hello all,
I hope you don’t mind me posting this query here, but I was wondering whether anyone else saw the odd thing (I hesitate to call it a UFO!) which my wife and I both saw while watching the Perseids last night?
Let me start by saying that we were both utterly sober and not under any kind of chemical influence (unless you count a cup of tea!). We compared notes after the event and had both seen exactly the same thing, so whatever the explanation, this object/effect was definitely visible in the night sky.
We were watching from South East Cheshire, England, and saw it around 22:20 BST (21:20 UTC). It appeared in Ursa Major and crossed the sky in a straight line almost directly overhead, travelling from West to East. It consisted of three dull orange lights, about the size and brightness of stars, in a slim triangle formation. The three lights made constant small random movements in relation to each other, while still maintaining their approximate formation. It’s apparent speed was two to three times that of an airliner at a few thousand feet (aircraft leaving Manchester airport regularly go over our house, which is why I use this comparison). There was no sound whatsoever.
The small random movements of the lights were one particularly strange aspect. The stars themselves were quite clear and steady, so I can’t put this down to atmospheric turbulence.
I have always been somewhat dubious about UFO sightings until yesterday, and I don’t blame you if you treat my report with scepticism, but I must repeat that my wife and I both saw exactly the same thing. Whether it was a solid object or an optical effect, it would have been visible to others.
So, I’m dying to know whether anyone else in the North West or West Midlands of England (or possibly further afield, depending on the object’s height) saw anything similar! Does anyone have any thoughts as to what it might have been?
All the best,
Paul Morris.
Congleton, Cheshire.
myself and my partner saw an orange object also last night(13/09/09) again in correspondence to your description it was indeed traveling at around 3 times the speed of an average airliner, it also travelled in a straight line across the sky directly overhead(we however are based in surrey) however the shape you desciped is differant to ours, we saw a shape not unsimilar to a large bird but this was aroud 1.30am and shining orange in the nights sky. i am very aware that satalites were visable as i saw at least 3 orbiting the sky as we wacthed for the phenominal shooting stars and none of these were orange they were all white lights that looked like very distant airliners. i would love to hear if you get any other responces from your qeustion.
They may have been LEO satellites which orbit in groups and rotate. I would search the internet on LEOs to get more info.
Hi paul, i am flo (aged 10) and I did an astronomy course a few months ago. please dont ignore this just because i am a child. anyway, if it looked like a slightly large star and it took about 2 minutes to cross the sky, and you said it went west to east, that could be the I.S.S. (Internatiol Space Station) but if it did not seem like a large star and went quicker or slower, it could be anything.

hi paul, i’m from malaysia.. interesting story to read here, because i also experienced the same on 3rd october 2009 at 9pm (local time) in johor bahru (JB) capital city of johor (southern state near singapore) saw 5 bright orange objects slowly maneuvering the city’s sky.. i saw it with both my parents that night. at first 3 objects flying straight in line then changed it into a triangle. then there 2 objects came closely far behind. i didn’t bring any equipment to capture the scene because we’re in car going to shopping mall that night. some people say that these ufo sighting happened due to series of earthquake in indonesia (or any other mother’s nature destruction), i’m not sure about that but it may relevant because my friend also saw it on september 2009 before the earthquake and myself saw it after. too bad there are no evidence from me and no other people so far had an experience that night same with me.
as i’ve seen in youtube (type: orange ufo in searchbox) after the sighting, it look the same like i saw in the video and interestingly same all over the whole.
We were also out watching for meteror showers on the night of Aug 14/09 at 11:15pm in Nova Scotia. We saw the same thing that you have described. It was three lights in a triangle form moving very quickly, low, and absolutely no sound. Does anyone have an explanation of what this might be?
sitting in Weybridge surrey, we saw about 30 to 40 of these, drifting across the nights sky.
The only difference was we did not notice any small iregular movements.
we saw about 30 in tow differant clusters. they were moving so slow and were a orange colour. we seen ashes falling about 100 feet away from us. we are in guelph ont.
I’m also in Guelph, ON! Neighbours on Alice St. pointed the lights out to me, there were about 15 of us in total that saw it.
We saw up to 7 at one time, all roughly to the north, perhaps 30 degrees above the horizon. All were moving roughly east, quite slowly. There seemed to be some minor movements to and fro. One or two of them just seemed to wink out.
Definitely not meteors, far brighter and larger than any satellite I’ve ever been aware of. None of us had ever seen anything like it.
Sorry that we have all hijacked the Perseid story’s comment section, but this is one of the stranger things that I’ve ever known, and I’m eager to see other folks who witnessed something similar.
I was on a summer camp at RAF Henlow in England at this time. We all got our camp beds and watched all night. It was amazing. I made a wish for every shooting star i saw, that very night my wish came true !! Also, my friend was amazed as he saw orange lights appear which he said looked like a shooting star had blown into a satellite. I didnt see any but he saw quite a few unidetified orange lights accorss the sky
[...] we can sing at the top of our lungs, “Here Comes the Sun,” [by the Beatles.] He sends shooting stars to cross over our camp fire. He sends the most precious little missie moo, an almost two year old [...]
hi everyone, does anyone know if i will see any perseids tonight? (17th august 2009)
Hi everyone,
Many thanks for your various replies regarding the UFOs. Its interesting to see how many people saw something similar.
I’ve had various suggestions for possible causes. One possibility seems to be Chinese Lanterns, released following a festival. These will float overhead following the wind, giving off an orange light. I have to admit that what I saw didn’t look quite right for this, and my wife has seen Chinese Lanterns before, and remembers them differently.
Neil and Wally in Guelph – could what you describe have been Chinese Lanterns?
Another possible explanation is that they are bits of military kit used to simulate missiles for training excercises.
I don’t think the ones we saw could have been any kind of satellite, due to their high apparent speed. To have crossed the sky that quickly and been high enough to be out of the atmosphere, they would have had to have been travelling well above escape velocity. Also, the East-West path over our latitude would not be the type of Great Circle that any orbiting object would follow.
Flo – your sighting sounds like it was moving much slower than ours, and could have been a satellite. I believe the International Space Station should have been visible, so that might be what you saw.

On August 14 , I was in Dallas Texas hanging out with my brother and my husband…just talking outside in the balcony, when suddenly…this enormous flare of light almost like fire came out of nowhere in the sky, shaped as a comet…like a bright ball of fire or light or who knows followed by a tail the same color crossing from west to east and becoming smaller as it travelled, finally ending with 2 or 3 burnt ashes left behind and dimming themselves. This lasted for about 8 seconds…my brother was freaked out because of my stare!!! Eyes wide open, mouth half open…I was really amazed…I kicked him so he turned around and see what I was looking at. Size? waaaay bigger than an airplane….had the shape of a comet, and the size…hmmm..can’t really tell….if you hold a quarter with your thumb and index finger lift your arm straight and hold the coin level with your eyes in front of you…that’s about the size of the thing I saw…not that close of course, but that size far away in the sky…hhmmm..I hope I explained that correctly…anyways, it was incredible…never seen omething like that before…only in movies like Deep Impact…that kind of appearance but without stone seen…just light or fire….very bright!!
Wow Monica,
Great description. Think you saw a fireball! (I haven’t yet)
Check the American Meteor Society link just above.
Thanks,
Kevin
PS. Sorry, the AMS link was not “just above” (I’m shocked, but very pleased by the popularity of this blog post!) Here’s the AMS fireball reporting page. Thanks again.
this is going to sound stupid but is it true were going to die in 2012 with a comet hitting the earth?
7:35 pm MST Today.
I just saw a large meteor streak. Brighter than a helicopter. Streaking from West to North East over East Mesa near Phoenix. It broke up in many pieces. It was brighter than the police helicopter lights. It broke up in many pieces like firework it spread out. It lasted about 3 seconds total. It was close.
