Perseid Meteor Shower Peaks Tonight
oxide7 writes "August's Perseid meteor shower has historically been providing the best opportunity for enthusiasts to catch meteor shows, but this year the Internet will let casual observers enjoy the show live online. The Perseids have been observed for at least 2,000 years and are associated with the comet Swift-Tuttle, which orbits the sun once every 133 years. Each year in August, the Earth passes through a cloud of the comet's debris. These bits of ice and dust — most more than 1,000 years old — burn up in the Earth's atmosphere."
a regular shower (rain, a little hail) and some thunder.
And the forecast is for mostly cloudy, so I don't think I will be seeing any meteors
The moon is going to be out and high in the sky tonight, drowning out most of the meteors. The best showers are when there's no moon out. This one is probably going to be pretty boring because of it, don't expect much.
After millennia of technological and social development, humanity has finally reached the point where it can broadcast one of the most magnificent spectacles of nature to all, in real itme, to all people! Just in time for a full moon!
While the best viewing would normally have been tonight or a few days around it, the Perseids hang around for a while, and you may be able to see occasional meteors for a while. I saw one just by chance last night, in spite of the moon, streetlights, the marine-layer haze in the Bay Area. You'll need more patience in a week, but the moon won't be as much of a problem.
What's more frustrating has been not knowing if the auroras from the recent solar flares would be visible down here (which is very rare), and it's been cloudy enough near the horizon at night that I probably couldn't tell anyway. (There was some green glow in the distance the other night, but then it turned in to yellow glow, and red, and green again, so it probably wasn't auroras :-)

Question to the knowledgeable: Is there any chance at all of seeing anything from here in New Zealand?
You many not be able to watch it because of the full moon but you could always listen to it here-

Even with the moon full, I was sitting in a hot tub outside tonight, staring up at the stars, and saw a ton of them, bright and easily visible.
I was parked in an empty field in North Dallas at about 4 AM and a large one came in from the north. As it traversed to the South just to the East of my location it broke up into several fragments that began to rotate about one another, it came to a stop and the fragments continued to 'orbit' one another for brief period before the light faded.
I have seen plenty of meteorites break up but I have never heard of this type of thing before. Has anyone an explanation for this phenomena?
This sig is not paradoxical or ironic.
In my 50-something years on the planet I have never observed more meteors during Perseid than at any other time. In total, I have seen about 3 meteors and I am outside a lot!
Well, i peaked your mom tonight too. And the Internet let casual observers enjoy the show live online.
Yawn...
Is somebody claiming that some of the cometary material is less than 1Ka (kilo-annum) old? I doubt that any of that material is younger than 3Ga, and probably older than 5Ga. Perhaps they mean that the material was mostly dislodged from the comet over 1000 years ago. Fine, but that's not the age of the material, which is generally taken to mean the age at which the material came to be in its present state (vs. location).
I'm wondering something: How come this happens always at the same time of the year? That cloud of debris can't just sit still (relative to the sun), doesn't it rotate around, or fall into, the sun, as years pass by? That should make the phenomenon happen at a different time each year... From my understanding, ignoring gravity due to Earth and other planets, something sitting motionless at this distance of the sun would fall into the sun in a matter of months? Unless there's a huge trail going straight away from the sun getting slowly eaten like a spaghetti, that somehow isn't disturbed by other planets, that gets crossed by the Earth once a year. *confused*
Observers are reporting a brief but intense peak between 10:00 and 15:00 UTC. Notable fireballs were seen. Here in the midwest, many locations were overcast. My radar scatter receiver recorded at least one large event every minute or so during that time, supporting other observations. There's always the Draconids in October and the Leonids in November. I think the 1,000 year old comment was either mis-quoted or misunderstood. Essentially the leftovers from the formation of the solar system, cometary material should match the estimated age of meteorites (oldest about 4.5 billion years old). But of course, how do you define "how old" something like this is? Some researchers have been able to estimate the individual orbits (or streams) that we're passing through. That may have been the source of the 1,000 year quote - e.g. this particular stream was from a Swift-Tuttle pass 1,000 years ago. Regardless, it remains the most predictable so far. Maybe a better show next year :)
