It doesn't look like typical meteorite pics so I'm asking for advice. One guy in the last thread (on /b/, I wrongly assumed some experts still /b/rowsed) posted a meteorite pic that looked strikingly similar to the shape as well as surface texture.

I don't have any magnets but some stuff clung on to my tweezers when I tried to sift through to show you guys big piece of what's fallen off.

This is the rock, the next pic will be some of the stuff that's fallen off onto what it was set on. I've taken this pic on standard printer paper for a size reference, it's 15lbs.

I even have a blurry video showing the stuff sticking to my tweezers if anyone can tell me how to make a webm.

Please refrain from commenting on here/hear typo in the OP. I apologize and am not realizing how out of it I currently feel.

Here's the "stuff", I'm currently showing how it surprisingly stuck to my tweezers, and if you note between this pic and the next the different in how much dark dust stuff is sticking to these little colored rocks I'm sure you can see that whatever this stuff is it's clearly magnetic.

Lunar Meteorites are worth $1000/gram. I was perplexed because the only pics I could see of meteorites were smooth, had a crust, all this other stuff that looked nothing like what I had. Then one kind anon posted this pic of a Lunar Meteorite in the thread I made on /b/. I checked out the website he linked it to and some of the pics look identical to what I have, right down to the same colored rocks inside when you cut it open that fell off the outside of mine in the first few pics.
>>
>>6564510
Funny story man, when I hold it my hands are gradually chilled to the bones. I don't really have a way to describe it. The rock itself isn't cold to the touch, it's a little cooler than room temperature but when I hold it for more than a few seconds the inside of my hands start getting really, really chilled. Creepy.

Here's the inside of a lunar meteorite so you can see the comparison of the colored rocks to what I posted just after the OP.
>>
>>6564410

How does your grandma know the rock wasn't there? I mean if she leaves shit like that laying around for a month, how can be sure the rock didn't come from somewhere else? Maybe someone moved it doing some yard work and she didn't notice.

Here's why I don't think it's a meteorite. If it hit her house, it would have went through the roof/wall. It wouldn't have just bounced off. If it hit the concrete patio, it would have cracked it and/or cracked the rock itself.

If you really want to stick with the story that it hit her house, I would ask if anyone is doing some blasting in the area. Does she live in the mountains?

I know a legit meteorite dealer. I've helped him handle some specimens. The 1000/gram stuff isn't common. I've seen small pieces of Mars meteorite go for less than that. I've seen a $4000 slice that used to be in a local museum and what you have isn't that either. You can trust someone to look at it. They're not going to beat you over the head and take it, especially if it's a professor.

It didn't hit her house, she thought something hit her house when in fact it just hit her porch. I had the same thoughts as you when I was told about it, it sounded ridiculous, I actually thought it had busted up the concrete, and if a meteorite did in fact hit, I was looking at busted concrete and the meteorite was something small sitting in the rubble.

However after looking at some of the other moon rocks and seeing that the little pieces coming off of it are magnetized I'm leaning towards thinking it might be legit.

Here are some other lunar meteorite pics that I've been using to compare the two.

Last one for comparison.

Like I said all I know is what I was told, after being told the concrete around the rock had turned white like it'd been heated, the first thing that came to mind was some kids in a pickup driving around in the back with a large rock, holding a torch and heating it up and then going 100mph and throwing it out and it ended up on her porch.

That was more plausible to me than it being a meteorite, but the more I think about it the more ridiculous that sounds.

Here's one more comparison for people saying it would have a huge impact and leave a crater. This is nearly the same weight as the one I have and in sand/pebbles this is the size of the crater it left. It's not what you see on TV. I would say if that hit concrete it might legitimately not crack it. (The concrete patio is 6" or 12" thick)

/sci/, how quickly can extremely small rocks lose their magnetic qualities?
>>
>>6564586
No. If something is radioactive, the EM waves will cause interference with electronic devices. Putting a camera close to a radioactive source will cause interference with the camera, and this shows up as snow on the viewscreen. You should see like little bursts of color on the camera screen. It should be fairly noticeable if you bring the camera close to a radioactive object in the dark, because the entire camera screen will be dark except for random pixels changing color for half a second. Some shitty cameras will do this regardless though, so try it somewhere else beforehand

A phone might work as well, but you'd probably have to use a corded phone and have the cord go right over the object. Otherwise you can't really tell if you're getting interference from radiation or just because your cell signal is poor.

You watch too much tv bro, meteorites won't even make a small crater unless they're something like 100lbs or more. I read a lot because it didn't make sense to me either at first, but apparently something this size will just land on the ground with a thud, or in this case the concrete.

Kitchen magnets don't work, but if you look here >>6565825 you can see that the colored pebbles inside have magnetic properties, and the shavings that have fallen off of it are sticking to them. However it looks much more like a stony meteorite than a metal one. I still haven't gotten around to cutting a piece off to send somewhere.

All the metal meteorite pictures I've looked at look WAY different than this, mainly because of the obvious fusion crust. However, Lunar and Martian Stony Meteorites look much more similar to this one and some can have little to no fusion crust. Don't ask me why, I'm not a scientist.

Lacking a fusion crust doesn't mean it is not a meteorite, sure most have them but some don;t and meteorites value is primarily determined by it's uniqueness so that is at least hopeful for op

>Grandma here's loud noise

I already knew what that rock was the second you posted this thread but I was banned so I had to wait till now to reply.

See these
>>6564622

Those are chondrules. And the redder pieces of rock are olivine and pyroxene.

And of course
>>6564471
Iron metal which explains the magnetization properties.

What you have here I am sure OP is a very common meteorite which falls roughly udner the H chrondrites, however,this is a rather rare type of H chrondite, so rare it doesn't really have a classification to itself.

However that being said I don;t think it is extremely valuable. but it should be more valuable than normal H Chronicles. When you cut it open you will see a beautiful cross section of the olivine and pyroxene which should appear as red and yellow circles within the rock and some glitter of iron.

All you've gotta do is fill a big container with water up to the very top and drop the meteorite in. Then you measure the volume of water that was pushed out of the container. This is the volume of the meteorite.
Then you just find the mass of the meteorite.
Then you divide the mass by the volume. Bingo. Density.

Also, how would you suggest cutting it? Just completely in half? Because I'm kind of strange, and feel it's a shame to cut it at all. I know it has to be done but I feel like it's a loss to disturb the preservation of it's natural form.

There is a small "knob" on the bottom that I could hack off, I was looking for a spot that wouldn't disturb any of the maximum dimensions of the meteorite. So I looked for something that wasn't something that any measurement would be taken to determine the meteorites maximum size. That includes extreme point of the X, Y, *and* Z axis. There is a small knob in a larger bowl type area on it that measures about 2.5x2.5 inches but I'm considering that it's possible this does have some kind of crust, and that spot may have been on the back end where the entire knob is made of crust. So it could be completely pointless to cut that off and I'll just have to cut again somewhere else.

Pic related, to be precise.

>>6568525
Neat, except I'm not dropping it in water. There's a lot of dust and stuff on it that's pretty fucking cool, so I don't want to wash it off.

Also, picking it up and flipping it over cause a piece that sounded large to fall and hit the cardboard, and I think I lost it.

Op, it's either shit either some useless rock.

It will surprise you but even rocks from the moon are not something special, there are tons of them on Earth.
>>
>>6568525
To give you a rough estimation the first pic is it sitting on a 9"x11" piece of printer paper and it's "height" is about 5 inches.
>>
Cut it in half. You're so lucky to be the guy that cuts it in half, and not the guy that gives it to someone else to handle... I'm very jelly. Open up the sucker!
>>
>>6568535
Actually man, no moon rock has ever been found on North or South America. It would be the first, also it would be the third largest ever found. But our friend who sounds like he knows what he's talking about is saying it's one of the most common ones.

You've convinced me. Now... what do I use? I have a lot of tools at my disposal. Circular saw, sawzaw (is that even how you spell that?), dremel (I don't know how to spell tools, I just use them) tool with a very small circular blade... chainsaw. Chainsaw? God that would be badass. Maybe on my next one.

You could do it with either a sawzall or a circular saw, I'd go with sawzall myself

Dude, I'm fighting the urge to swallow a small piece of it just to say that I did.

Lots of sociology subjects in past degrees and I'm currently working towards becoming a teacher. American teacher standards aren't that great and the curriculum is pretty silly right now. I miss the days of primary students being hands on with stuff like displacement. Remember to be a good dad and do this sort of stuff in the yard with them!
>>
>>6568552
I'm so excited to see these pictures.
>>
>>6568552
It would probably be a win win for us, if you got sick it signals that something on the meteorite is making you sick which would be cool
>>
>>6568557
I have to wait for my dad (not underageb&, economy stuff) and he's bitching about not wanting to cut it right in half. Some website he found said they only want you to send them 4 grams or so, and that's pretty small.
>>
>>6568580
Put a good magnet near it. Does it stick?
>>
>>6568589
I can't find my 2"x2"x3' industrial magnet, and kitchen magnets don't stick, no. However, if you read the thread you would see that material that fell off is magnetic, as demonstrated in the .webm that I posted showing them attaching themselves to my tweezers.

Seriously though I just want to cut it in half and see if I can get a space ruby to fall out of the middle.
>>

b-b-break a bit off so we can see the inside
>>
>>6568619
About three and a half hours when my dad gets back from his dr. appt. He said he's got a handsaw with a very thin blade, still only going to cut off a very small piece though. It's probably going to be like 1/2 or 1/4 inch viewing hole. I feel like I'm going to be disappointed. I really do want to cut it in half and view the beauty of what is inside, if I could I would cut it flat ways from one side to the other so I would be left with a top and bottom half and could have the most viewing surface as possible.

Ok, here's something I'd like to know. Why doesn't it have a fusion crust? I mean, they're supposed to heat up right? Unless an alien came down and dropped it 100 ft or so over my grandmother's house... hmm...

There are chondrules literally falling off the outside, that seems really strange to me. Especially since they're almost like spongy rocks and felt like bread crumbs in my fingers the first time I picked one up.

The meteorite was sitting on a paper plate, I literally thought someone was stupid enough to sit it on a used paper plate and I was picking up stale bread crumbs. That seems like it would burn off or something, so why didn't it?
>>
>>6568467
>Lacking a fusion crust doesn't mean it is not a meteorite
if it supposedly just fell and it doesn't have a fusion crust then that's a pretty strong indicator that it's not a meteorite.
>>
inb4 OP gets a virus from an ancient version of earth that got hit by a meteor and the chunk that OP got flew off into space then came back after bouncing around the universe for a while.

You never even heard the fukken eureka and naked dude story?
>>
>>6568809
That just goes to show how misinformed people are on the internet, it was practically a witnessed fall son.

>Grandma chilling in her house
>Hear wall shaking BOOM
>Grandma goes to look
>Sees rock that wasn't there a minute ago

Regardless of whether or not it's likely, what you're looking at is a meteorite without a typical fusion crust. Take a good look, because now you know what that looks like and can identify other meteorites without fusion crust and feel superior to your fellow man, like I know you like to do.

I just woke up, and my dad is still awake about to go to bed. I should be cutting it open somewhere around noon or afternoon.

Not a lot adds up to it being a meteorite. A lot of things are off about this but who knows it's not out of the question. .

the only way your actually going to find out if it's a meteorite is if you bring to someone that knows their shit, prob at a local university. Don't give it to them if you dont feel comfortable doing that but your going to need a professional opinion. maybe let them cut off a small sample. don't cut and mangle it all to shit yourself cus maybe you have some rare type and it'd be worth a lot to a collector. Probably not but it's worth taking into consideration. They aren't going to fuckin bash you over the head and run off with it so you don't need to worry about them saying its worthless and taking off with it. If they bring it up, make it clear your not going to sell it to them without second opinions and whatnot so they have no motivation to lie about it. I think it's definitely worth checking out.

Also, look into sightings in your area around the time you Grandma heard it. Something that size may have been visible coming down.

One of the anon's that sounded pretty informed >>6568467 recognized the stuff in this pic >>6564425 as chondrules. People are saying the red stuff looks like this and that, but everything they're suggesting it may be are very hard crystals with specific and defined shapes. While this stuff is brittle (the smaller pieces anyway) and not very well defined.

I didn't find anything around Jan/Feb this year but I did find this website.

http://www.nuforc.org/webreports/ndxlFL.html

I ctrl-F my city and am seeing that people have seen strange crafts flying around with jets following them and stuff recently. Feels pretty weird man.

Really. I was out of it and I apologized in the second post bro.

Also I found something pretty neat, a gif of a meteorite flying past a skydiver.
>>
>>6570382
I think I heard of this on /sci/
It's really cool because it's one of the first times that a meteor has been photographed in the dark phase of it's travel (when it's not burning up).
>>
>>6570385
There was also that one time where it was night, the guy was standing by the pool and then BOOM a fireball comes out of the back of his chest and lands in the pool. He died.

Anyone tired of this OP fag not having cut the rock open already? I know I am.

There's a video of it somewhere, and they recreated the event on 1000 ways to die. He was standing on a deck, leaning on wooden railing in front of a pool. The meteorite came through the middle of his chest and landed in the pool. He was not alright.
