Close-Shave Asteroid Caught on Camera and what is this?
I dont know if this was posted yet. Check the animation and see one asteroid passing in the sky. But you can also see some kind of explosion near the middle of the image (?)


When asteroid 2010 RX30 zipped past Earth early Wednesday, observers at the Remanzacco Observatory in Italy were ready. At 12:45 a.m. Mountain time, amateur astronomers Ernesto Guido and Giovanni Sostero remotely controlled a 0.25-meter telescope in Mayhill, New Mexico, through the Global Remote Astronomy Telescope Network. They got four separate exposures of 30 seconds each and stitched them together to make this animation.

what is this POOF cloud besides it in the beginning?

possibly something made sure it will not hit us tissue

Re: Close-Shave Asteroid Caught on Camera and what is this?
judging by the size of the 'poof' in the images, it could not have been at the same distance as the object which is the focus of the images. Look at it again. Do you see the relative size? For something to be that big at that distance, it would have to be truly mammouth.

Now consider that the 'poof' happens, then dissipates in the order of two minutes or so (the images are 30 seconds apart at exposures of 30 seconds). Having seen the trail a rocket leaves, I can tell you that it lasts much longer than 2 minutes. I once watched one reflect light for over 3 hours.

So, barring any evidence to the contrary, I'm going to suggest that the anomoly shown in the photograph is probably a short-lived condensation of water vapor, possibly relatively low to the ground (as a higher-up cloud would stick around a bit longer, while lower ones exist in a much more fragile and chaotic environment).

Of course I remain open to other ideas.

I m not familiar with this, but thanks for your explanation. It looks like an 'exotic' explosion to me but as you noticed it lasts very short time.
