Re: [meteorite-list] Noblesville IN possible meteorite landing December
Once it enters dark flight it is largely subject to what the wind is doing. Within a few seconds it is simply falling at terminal velocity. Of course, it depends on what we mean by "break up". I'm talking here about a terminal explosion, which is a common way that meteorite producing meteors end up. There are also meteors that break up over a long distance, in a series of explosions or disruptions. Those tend to drop meteorites along that path, producing long strewn fields. In any case, if you see a fireball near the horizon, there is no way it can drop meteorites anywhere nearby.

Re: [meteorite-list] hot vs. cold meteorite falls
A meteoroid in space is nominally at or just above freezing (i.e. 0° C), but there is a fair range around that, especially toward the higher end, depending on its emissivity. It almost certainly will not be very cold. Space is not "cold". It is, of course, dominated by radiative heating and cooling. While it is radiating into something just barely above absolute zero, it is also absorbing the same amount of solar energy as a rock on the ground. In most cases, I would expect a meteorite to be on the cold side when it impacts. The heating that occurs during its brief ablative phase will have almost no effect on its internal temperature. But it will spend several minutes falling through air at one or two hundred meters per second, and for almost all of that time the air will be on the order of -40° C. That will result in significant cooling of typical meteorites of a few hundred grams to a few kilograms. I think that what can easily happen is that people who touch a freshly fallen meteorite actually experience cold as hot, due to their expectations. Whether we perceive something as hot or cold can be unrelated to the actual temperature. Remember that kids' game where you dare somebody to keep their back to you while you touch the back of their neck with a hot iron, and then actually touch them with an ice cube? Most people startle and believe you've burned them. Chris *** Chris L Peterson Cloudbait Observatory https://www.cloudbait.com On 3/22/2021 1:37 PM, Eric Christensen via Meteorite-list wrote: There was a recent discussion on a social media forum about a stone from the recent Punggur fall being warm enough on impact to melt a synthetic bedsheet. I followed the discussion with interest but don't have an account on that platform - so wanted to post here. The original poster also referenced the other recent Indonesian fall (Kolang), where a finder reported the stone felt as if it had been "cooked with sunlight". There are many other references to freshly fallen meteorites being warm or hot to the touch, or sometimes cold to the touch. The oft-repeated rebuttal is that meteoroids come from the icy void of space where they must be extremely cold, and that any brief heating experienced during the luminous ablative phase will dissipate during the few minutes of dark flight through the atmosphere. Also, that the human brain will trick surprised finders into misinterpreting "very cold" for "very hot". It seems to me that there's an obvious error in this argument - the initial condition of a meteoroid being very cold is not (necessarily) true. In fact the opposite can be true - meteoroids (or asteroids) can actually be very hot prior to Earth impact. "Cooked with sunlight" is an extremely good description. Consider figure 1 from Delbo and Harris "Physical properties of near-Earth asteroids from thermal infrared observations and thermal modeling", published in 2002 in MAPS: https://onlinelibrary.wiley.com/doi/pdf/10./j.1945-5100.2002.tb01174.x The sunlight side of a model asteroid at 1 AU has a temperature of about 400 Kelvin = 127 C = 260 F. The side facing away from the sun will be cooler; how much cooler will depend on the thermal inertia of the body, pole orientation, rotation speed, etc. There may be steep temperature gradients across an asteroid at impact time, or it may be relatively equilibrated. Most meteorite droppers should fall into the latter category, being small (sub-meter), fast rotators, and regolith free. How much heat is gained during ablation, and retained during dark flight, ought to depend on the thermal inertia of the meteorite. Metal-rich meteorites or those with low porosity ought to retain more heat, and be less efficiently cooled during dark flight. So - are fresh meteorites hot or cold on impact? I think the answer is, "it depends!". One could even contrive a set of circumstances where an asteroid with a large thermal gradient drops two meteorites of equal sizes right next to each other, coming from different parts of the asteroid, where one lands hot and the other lands cold. Tarp-melting hot? I don't see why not. Cold enough to form frost? Sure. Hot enough to ignite a grass fire?

Re: [meteorite-list] Seismic Event w/ Bolide?
I'd also like to point out that the description of "magnitude 2.0" is rather sloppy. Seismographic magnitude scales (e.g. Richter, moment-magnitude) attempt to provide a measure of the energy released by an earth movement, at the epicenter, focus, or along the moving section. It is completely separate from a measurement of intensity (e.g. modified Mercalli scale). For a geological seismic event, the magnitude is fixed but the intensity varies with distance and various geological factors. What the seismometer was directly measuring here was intensity. Perhaps by "magnitude 2.0" they meant the intensity was the same at the measurement station as what would have been recorded if it were at the epicenter of a magnitude 2.0 earthquake. Anyway, the useful information is apparent in the actual data which show the signature in terms of ground velocity versus time. From that it is possible to derive actual information about the energy dissipated in the atmosphere and delivered to the ground. Typical kinetic energies for fireball events like this may be on the order of 10^11 joules or more- say, 100 tons TNT equivalent.

Re: [meteorite-list] Hot vs Cold again...wasmMeteorite Crashes Through Thailand House Roof
The fusion crust will likely be warmer than the interior when the meteorite hits. Not because of residual heat from melting, but because for the last few tens of seconds of the fall the meteorite was being blasted with near-ambient temperature air. It was starting to warm up to ambient- it simply didn't have enough time for that process to proceed beyond the outer few millimeters.

Re: [meteorite-list] Hot vs. Cold again...
Also important is to consider that the body in space may well have been a good fraction of a meter (or more) across. But a meteorite producing body didn't just ablate, it most likely fragments. And the small fragments very, very rapidly drop below the speed necessary to sustain ablation. So what we have left is fragments that are probably a bit below freezing being blasted for several minutes with very cold air. Small fragments means not much volume, but lots of surface area, so the heat transfer is pretty efficient. It's hard to imagine a scenario where a meteorite is warm on landing. The interior will be cold, and the outer few millimeters might be near ambient, simply because of the warmer air encountered over the last minute or so of dark flight. But within a minute I'd expect the outside to get colder again because of transfer to the cold interior.

Depends on how "black" the original meteoroid was. Equilibrium temperatures for irons are quite a bit warmer. The radiative cooling during dark flight is probably calculable and a missing factor in estimating the state of heat content upon landing. Not just a missing factor -- perhaps the dominant factor. 3-5 seconds of ablation is nothing compared to 2-8 minutes of freefall through atmospheric temperatures as low as -70 C. Basically you have a frozen, baked Alaska situation: pre-atmosphere, a cold body through and through. Then (in the case of non-irons), you expose this low-thermal- conductivity mass to a brief blast of extreme heat that boils off the exterior almost as fast as the heat can be conducted to the cold interior. Bur almost as soon as it starts, it's over. You have a thin crust of hot material surrounding the still ice-cold interior. And for the final act, you refreeze the exterior for a time period 20 to 100 times longer than the ablative phase. For stony meteorites, there just isn't enough time to raise the bulk temperature of the body. So I disagree with this statement: "An immediately-recovered, newly-fallen silicate/stony meteorite is usually--but briefly "hot/uncomfortably warm" to the touch. The rind is very hot but lacks much heat reservoir." As long as there is an extended period of freefall through the atmosphere (a very reasonable assumption for non-cratering events), atmospheric cooling will always win out for a stony meteorite. --Rob __ Visit our Facebook page https://www.facebook.com/meteoritecentral and the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list __ Visit our Facebook page https://www.facebook.com/meteoritecentral and the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Meteorite Crashes Through Thailand House Roof
There's really no way for such a stone to be heated significantly by the energy dissipated when crashing through a roof. In all likelihood, the reason that observed falls are reported as hot is because people expect hot, and confuse hot with cold. I don't think the incidence of reports of heat is significantly higher for hammers than for other falls. FWIW, when you pull a nail the mass of the nail is very small, it has a high surface area compared with its volume, it's thermally conductive, the extraction is relatively slow, and the friction is very high. Contrast that with a meteorite: much smaller surface area compared with volume, low thermal conductivity, very high speed of impact, and very little friction (with most of the surface never even contacting the roof).

Re: [meteorite-list] Very Bright Fireball Over Europe on Halloween Night
Hi Doug- I don't think atmospheric extinction normally plays much of a role in color perception of bright meteors. You don't get a full magnitude difference between red and blue until you are about 15° above the horizon, or about four air masses. And even at a magnitude difference, I'd only expect a small impact on perceived color. Angle, however, translates to apparent speed, and I do think that might be an important factor in how people perceive color. I will say, however, that I haven't found any sort of systematic shift in color reports based on the distance from the fireball to the witness.

Re: [meteorite-list] Witness information that is more helpful than color
I seek color in submitted witness reports, not necessarily to provide additional scientific information (although it's data, so I wouldn't completely rule out that possibility), but rather, to understand how people see things differently, and to make for a more complete public report, since public education about fireball events is part of our function. Meteor color is as much a part of the phenomenon as brightness, speed, fragmentation, and everything else. The fact that we can't directly convert color into composition doesn't mean we shouldn't include this information in a complete report.

And human eyeballs/brains are a poor substitute. We don't have the necessary spectral resolution, and of course the optical response is far from flat. It is perhaps not coincidental that green-blue (0.498 microns) is the peak of our scotopic response. Deep red (>0.63 microns) sensitivity is almost non-existent in scotopic vision, so even if a fireball had a significant red component, a much smaller green component would swamp it just due to our spectral response. Since nothing really diagnostic can be learned from a witness's perception of a fireball's color (as far as the meteoroid's composition is concerned), I see little point in asking them or encouraging them to report it. The next best thing that a novice witness can report (other than an accurate time and duration) is the slope of the meteor track relative to the horizon -- perhaps using a clockface analogy to avoid scary geometry. If I know the approximate fall zone reasonably accurately, a distant observer's slope approximation can greatly narrow down the true flight bearing, even without azimuth information (which can already be inferred from their location relative to the fall with greater accuracy than they can report). Mike Hankey has put together some very nice tools on the AMS site for amateurs to contribute useful information, concentrating on those things that non-technical people are reasonably good at.

Re: [meteorite-list] Very Bright Fireball Over Europe on Halloween Night
Meteor color is important. It's just not a very useful measure for determining composition. Color changes with meteor speed and meteor depth in the atmosphere. And certainly, the composition is a factor, both in terms of chemical composition and bulk properties. But the relationship is complex, so there's no simple correlation between these things and color that we can make much use of. Common groups of factors tend to lead to common colors, which is why we see specific colors with specific showers.

Re: [meteorite-list] Very Bright Fireball Over Europe on Halloween Night
The whole issue of meteor color is complex. We now have many examples of high resolution meteor spectra... but "color" is a physiological phenomenon that isn't always easy to relate to physical spectra. The light of meteors consists mostly of thermally broadened atomic emission lines- lots of them- from both the meteoritic material and the atmosphere. As has been noted, the atmospheric contributions tend to dominate. But there are often strong lines from meteoritic material, as well. In the case of large fireballs (where we have much less spectroscopic data) there may be a blackbody contribution as well, either from the ablating surface or from a supercompressed plasma. And since this is mostly driven by thermal effects, the speed of the body makes a big difference in perceived color. Throw into all of this the complexities of human vision- differences in retinal response, persistence effects, psychological effects given typically short observation times- and it's little wonder this entire area remains poorly understood. After large fireballs, when I get many witness reports submitted, I review color. It's common for about half the witnesses who report color to agree on one in particular (green is by far the most common), while the other half see red, orange, yellow, or blue. My takeaway is that we should generally assume that most color is coming from atmospheric contributions, probably modified slightly by meteoritic components (often too subtly for people to report accurately), and that above all, it's almost impossible to make any assumptions about meteoroid composition from color.

Getting tired of hearing that a green meteor tells you anything about its composition. I know that it's natural for people to think the most important thing they can report about a meteor is its color, but I wish various broadcast media would do the public a service and disabuse them of this notion. It would be far better if witnesses could be trained to get in the habit of counting the duration accurately, and noting the exact time of the meteor to the nearest minute. Seeing as how almost everyone has a cell phone these days, and all cell phones have accurate clocks, there really is no excuse to get the time wrong.

It's a science myth inspired by High School Bunsen burner experiments that appears hard to kill. While composition in some cases does have some influence on the colour, it is actually the composition of the atmosphere that is usually dominant for our perception of meteor colours. That certainly is true for green colours. Meteor spectra show that meteors usually are very strong at the "forbidden" Oxygen line at 5577 Angstrom (557.7 nm). This line is due to atmospheric Oxygen, the same atmospheric Oxygen exitation line also responsible for the green colours of Aurora.

There is nothing definitive about it.
