Re: [meteorite-list] Current Sericho Habaswein Pallasite Prices

[Adam Hupe via Meteorite-list]

One dealer was offering Brenham, a well-known ruster with the 
description, No artificial preservatives or coatings where used in its 
preparation, like this was some kind of selling point.  I think the 
referenced examples of Sericho/Habaswein were not clear coated thus the 
dull appearance.


The same claim was made for Seymchan and Brenham about the the supply 
drying up yet 12 year later, there is still plenty on the market.


In the end, buyers determine the price, not dealers.  This was proven by 
undocumented lunar material being placed on the market with no dealer 
added value whatsoever.  Some well-known dealers, thinking more of their 
own skills than that of research scientists, went as far as providing 
COAs for material that they, themselves, had deemed to be lunar with no 
laboratory input.

Re: [meteorite-list] Seismic Event w/ Bolide?

[Matson, Rob D. via Meteorite-list]

Hi Greg – Chris Peterson summed it up nicely. I would venture to guess that 
bolides that
lead to meteorites on the ground more often than not generate detectable seismic
(i.e. acoustic) signatures. Of the U.S. recovered falls since 2010, at the 
times those
events occurred I found seismic evidence for Lorton (2 stations), Mifflin, 
Battle
Mountain, Creston (4 stations), Osceola, and Dishchii’bikoh (4 stations). (I’m 
sure
the Novato, CA, fall also led to seismic returns on many stations, but I never
analyzed seismic on that event – probably should do so for completelness.) The
Wolcott, CT, event on April 19, 2013, also produced a sonic boom signature but
no meteorites were ever recovered. There have probably been close to a dozen
other bolides in recent years that I found on seismic, but meteorites weren’t
recovered.  --Rob

List,

Has there been other bolide events that have had a seismic correlation? It is 
being reported that USGS recorded a 2.0 magnitude seismic event with this 
morning's Michigan et al bolide event.

I would think that would have to equate to enough kinetic energy upon impact of 
the main body to create a crater of some size.

Thoughts from experts like Mr. Matson ;-)

[meteorite-list] Fwd: 1/17/18 Bolide-Seismic Event

[Greg Redfern via Meteorite-list]

Dear List,

Thought I would share this info from Dr. Larry Ruff, University of Michigan.

Greg Redfern

Dear Greg,
I'll try to provide some quick responses to your questions:

"Is that due to the proximity of the bolide to the seismic monitoring
station(s) or some other factor? How many have you seen?"

Yes, it is the combination of proximity & event size that makes the
largest wave amplitudes.
Over the years, this is the ONLY clear meteor-generated waves that
I've seen at Ann Arbor.
IN the past I have looked for waves at Ann Arbor from 2 large sonic
booms (one over Lake
Michigan, the other over Ohio), but did not found any waves above noise
level.

"Also, is there any way to correlate the USGS Magnitude 2.0 assessment
to the amount of kinetic energy released in the form of the acoustic
waves from this bolide event?"

Very difficult and tricky. The magnitude scale was developed for
seismic waves from
earthquakes, and the wave characteristics are quite different from an
atmospheric event.
Previous scientific work shows that there is fairly weak coupling from
air waves to seismic
waves, so any energy connection is poorly determined.

"Finally, is U-M mounting an information campaign to educate the
public on what to look for in terms of new meteorites."

As I far as I know, there is no public educational campaign today, but
there are a few faculty
who want to go find some meteorites if they can get a more precise
location for the debris.

regards, Larry Ruff

Re: [meteorite-list] Odp: Current Sericho Habaswein Pallasite Prices

[Mattias Bärmann via Meteorite-list]

I agree, Tomek. The quality in the case of Sericho seems to differ 
dramatically, depending on very different places the stones were enbedded.


The 2 pieces of /better/ quality (link 1): bidding has reached 42 $ for 
6.2 g respectively 51 $ for 14.6 g (and still 4 days to continue).


I would not recommand to wait until the worst and cheapest pieces appear 
on the market.


Best as ever

Re: [meteorite-list] Seismic Event w/ Bolide?

[Chris Peterson via Meteorite-list]

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.

By way of follow-up to my prior post, a significant seismic signature for the 
Michigan
event can be found on the US.AAM Ann Arbor seismic station at 01:10:16 UT on
17 January 2018. I've created the following link for you to display the 
waveform:

Re: [meteorite-list] Current Sericho Habaswein Pallasite Prices

[Bigjohn Shea via Meteorite-list]

As mentioned before, those really are not good quality specimens. Not very 
representative examples, Adam.

Also the 2kg or bigger specimens/lots of Hasbaswein have been selling for 
0.50$/g or less from the source for months now.

Regardless of size or price changes (which are temporary anyhow) once the 
supply dries up people will wish they had gotten the specimen they wanted when 
they could.
