Amazing. The amount of light it produced when entering the atmosphere was impressive, I said damn.

Any updates on this?

Did you see it?

On a day that had a lot of people talking about meteorites and asteroids, a fireball of some sort was seen steaking across the Bay Area skies.

The fireball was seen just after 8 p.m.

There are reports into the newsroom from people as far north as Fairfield and as far south as Gilroy. It was also seen in Sacramento.

It was bluish in color and appeared to be heading straight to the ground, according to one viewer in Santa Clara.

It comes on the same night a 150-foot-wide asteroid was due to come within 17,200 miles of Earth. It was not immediately clear if the fireball had any connection to the asteroid.

It also happened about 24 hours after a huge meteorite fell from the skies over Russia's Chelyabinsk region, resulting in a powerful blast that injured nearly 1,000 people and shattered windows across the area.

Chelyabinsk health chief Marina Moskvicheva told the Russian news agency Interfax that 985 people in her city asked for medical help and 43 were hospitalized.

Many of the injuries were reportedly from broken windows as a result of a sonic boom that followed the initial impact of the meteorite.

Honestly I wouldn't even rule out a widespread hoax.

[chuckddd]

Everyone in the bay area doesn't drive around with dash cams?

 

[HelloMeow]

I'm so confused. 4:30 it passes overhead, but it's not until 6:52 for detonation? Surely at around 4:40 or whenever it careens by overhead, it's just seconds from the ground? wtf

It struck Earth's atmosphere at 40,000 mph and broke apart about 12 to 15 miles above Earth's surface.

Isn't the daily telegraph some shitty tabloid?

I think the detonation actually happened mid-air and not when it hit the ground. I guess it's waaaay much higher above the ground then you'd think from the videos.

the speed of sound = 343.053 meters / second

So the video was taken from a bit over 30 miles away from the blast(in a straight line, I'm too long removed from school to do the math from ground level to the point below the explosion).

Light travels faster than sound does. It is like the time delay between the flash of lightning and the crack of thunder. Just as you can measure how far away a lightning strike was by how delayed the thunder is, the time delay here serves as a measure of the distance of the meteor from the ground.

What you can take away from this is that the meteor was very far away and moving very, very fast. The mind wants to compare it to a plane passing overhead, but the distance and speed are on a completely different scale. Remember, this rock was moving so fast that the air friction caused it to burn up and explode.

Also, based on earlier reports, the shockwave was that of a sonic boom, not an explosion. That blast was the sound caused by the meteor passing by, not some ground impact or explosion. Meteors apparently move ridiculously fast.

Reports of a fireball in the sky in the Bay Area?!

That sounds like a good estimate

 

[The Living Tribunal]

Apparently, had the meteor not broken up, by whatever means, it would have been another Tunguska event:

The estimated size of the object, prior to entering Earth's atmosphere, has been revised upward from 49 feet (15 meters) to 55 feet (17 meters), and its estimated mass has increased from 7,000 to 10,000 tons. Also, the estimate for energy released during the event has increased by 30 kilotons to nearly 500 kilotons of energy released. These new estimates were generated using new data that had been collected by five additional infrasound stations located around the world - the first recording of the event being in Alaska, over 6,500 kilometers away from Chelyabinsk. The infrasound data indicates that the event, from atmospheric entry to the meteor's airborne disintegration took 32.5 seconds. The calculations using the infrasound data were performed by Peter Brown at the University of Western Ontario, Canada.

The heck, it didn't look like a 500kt detonation to me. Chelyabinsk should consider themselves lucky.

Ironic, but also plausible.
If (semi) intelligent life formed on this planet again, they would teach the young that god was angry with us, so he threw a giant rock at us. From that moment stoning will be all the rage.

It's amazing how wrong the initial estimate of the meteor was. The Russians first said it was probably about 10 tons. Now NASA say it was 10,000 tons. Dat upgrade.

A 1 in 100 year event. It's great that we got some video of it, but I feel a bit sad knowing we probably won't see another one like it in our lifetime. Would love to have seen it with my own eyes.

NASA said "The estimated size of the object, prior to entering Earth's atmosphere"...

I believe Russia's estimation was at time of impact...

Have they found abandoned spacecraft with facilities for giant humanoids at the crater?

No they didn't mention anything about impact, the initial estimate of the mass was about 10 tonnes. There is no way any of the fragments that reached earth would have weighed that much.

the speed of sound = 343.053 meters / second

So the video was taken from a bit over 30 miles away from the blast(in a straight line, I'm too long removed from school to do the math from ground level to the point below the explosion).

You can use the old method we probably all used as kids to guess how far away lightning strikes were by counting the time between the flash and the thunder: 340 meters/second is 0.2 miles/second, so sound travels about one mile every five seconds.

So for a sound to travel 30 miles it takes around 150 seconds, or approximately 2.5 minutes.

 

[jobber]

A little outdated, but appropriate (not quoting for impact):

well...

it was the star wars project that was created in the 80s. Its a giant satellite with a laser orbiting Earth designed to shoot down any missiles Russia shot at us.

I just heard a big boom in San Jose, California.

Just got woken up by it... I don't see any trails in the sky though. Anyone else hear it near here?

Also, apparently Cuba just had one too.

Can someone tell me what got RT banned originally ? I've been visiting their english website for quite some time as I like that they report on stuff Western media sometimes don't. Them reporting that Russian Air Defense intercepted the meteorite would be the first time they've let me down.

Also, why are they banned but not Fox News ? I mean, what.

And the speed of sound is lower in a thinner atmosphere than at sea level approx 660mph compared to 720mph.
What would have happened if the meteor had entered the atmosphere at a more direct angle, say 90degrees instead of what looks like a 48degree trajectory?

Because it's not even a proper news outlet. The only reason it exists is to push pro-Putin/Kremlin and anti-US/West propaganda.

Stop listening to them.

Care to back this up ? I've never had this feeling. Then again, I don't really pay attention to what they say about Russian politics. But if your definition of anti-US propaganda is them reporting on sensitive issues that western media avoid, I ain't got any problems with that.

If the names of American guests on RT are unfamiliar to many Americans, there’s a reason, said Jonathan Sanders, a former CBS Moscow correspondent.

“Their guests are people on the fringes of respectability and cranks,” said Sanders. Source

Is pravda, comrade.

As the names of the main Communist newspaper and the main Soviet newspaper, Pravda and Izvestia, meant "the truth" and "the news" respectively, a popular Russian saying was "v Pravde net izvestiy, v Izvestiyakh net pravdy" (In the Truth there is no news, and in the News there is no truth). WIKI

Thanks for the read. Interesting. I wasn't aware of that side of them; but like I said, the reason may be because I avoided anything related to Russia, really. Your article even said that RT does good journalism when not talking about politics or spinning russia in a positive light.

So I ask Gaf: what is a great, truly objective, independant, fair and balanced medium outlet ? I'm sure there are a shit ton of them on the Internet, but the only two I know of are BBC and Al Jazeera.

Objectivity is a pursuit, not a reality. Every single news outlet will have its flaws and bias. Its best to balance out your information with multiple sources.

If I could choose to die in one way I would like it to be something like this. I mean, it's like the ultimate experience.

I'd rather we fly to the stars first pal. And can we not turn this into a political crap thread? Please? I was enjoying the thread until that.
