In regards to the Russian event take into perspective that it was daytime and the Sun has a Magnitude of -26.74 yet in more then a few videos it was clear that the luminosity of this meteor was much brighter then that since you can clearly see a washout of the natural shadows and they are replaced by moving shadows from the passing Fireball. Also the aperture on some of the videos was set to the ambient light automatically however when the Fireball passed over it was a complete washout because the Iris was open to much for the large amount of light that was entering.

Thanks for the numbers DerAlte, very interesting. The media and Nasa talking out there ass does not shock me in the slightest hence the reason I presented my hypothesis here that we are possibly seeing events associated with the asteroid regardless of what NASA is telling the general public, I feel they don't want to mention it to avoid the panic it might cause.





Knowledge is useless to useless people...

"I see a lot of patterns in our behavior as a nation that parallel a lot of other historical processes. The fall of Rome, the fall of Germany — the fall of the ruling country, the people who think they can do whatever they want without anybody else's consent. I've seen this story before."~Maynard James Keenan

@Sedit

My number for mag. of the moon was transposed - should have read -12.7 mag.

Quote:
According to NASA experts, the meteor was brighter than the sun when it fell into the atmosphere, and remained visible for about 30 seconds.
*Edit added 21 Feb.

Comparative estimates for Tungaska are given in wiki;
Quote:
Although the meteoroid or comet appears to have burst in the air rather than hitting the surface, this event still is referred to as an impact. Estimates of the energy of the blast range from 3 to as high as 30 megatons of TNT (13–130 PJ),[8][9] with 10–15 megatons of TNT (42–63 PJ) the most likely[9]
i.e. about 20 times as high. But the damage done was enormous:

Quote:
The Tunguska explosion knocked down an estimated 80 million trees over an area covering 2,150 square kilometres (830 sq mi). It is estimated that the shock wave from the blast would have measured 5.0 on the Richter scale. An explosion of this magnitude is capable of destroying a large metropolitan area.[11] This possibility has helped to spark discussion of asteroid deflection strategies....


At around 07:17 local time, Evenks natives and Russian settlers in the hills northwest of Lake Baikal observed a column of bluish light, nearly as bright as the Sun, moving across the sky. About 10 minutes later, there was a flash and a sound similar to artillery fire. Eyewitnesses closer to the explosion reported the sound source moving east to north. The sounds were accompanied by a shock wave that knocked people off their feet and broke windows hundreds of kilometres away. The majority of witnesses reported only the sounds and the tremors, not the sighting of the explosion. Eyewitness accounts differ as to the sequence of events and their overall duration.


yet this object drops into a lake 'in a village' and people survive there?

No doubt a more rational picture will emerge, give some time to elapse.

Are you saying KEF-2013 was Earth's satellite? Or Earth's quasi-satellite? Because either way, it's highly improbable and also impossible to prove, and Occam's razor suggests that it's a random collision because it came from a totally different direction, and the possibility of it KEF-2013 being a part of 2012 DA14's flock that somehow got pounded by something (what?) is even less probable because there'd have to be two improbable events.


Hah! Endimion17, I had intentionally been avoiding explicitly invoking <a href="http://en.wikipedia.org/wiki/Occam's_razor" target="_blank">Ockham's razor</a> <img src="../scipics/_wiki.png" /> (<em>lex parsimoniæ</em>;) against Sedit's argument. Way to blow it! :P Now the argument's just no fun for me.

I remember reading something about a theoretical (back then) method to blast (or nuke, depending on size) meteorites out of collision course with eath. It seems odd the Russians didn't see this one coming, Chelyabinsk was home to Russia's first nuclear weapons program.
