météorite Richardton, Tungunska et comète Encke

une réflexion de Steve Schöner, lamelliste

The Rickardton Meteorite fall of June 30th, 1918

The Richardton Meteorite of North Dakota fell at 9:48 PM, and I wonder if
this fall could be related to the Beta Taurid meteor shower, thought to be the
source for the Tunguska event of June 30th 1908. The Beta Taurids are a
daylight meteor shower starting at sunrise here in the United States, lasting
throughout the day and then below the horizon at the end of the day. Though
improbable, could it be that the Richardton Meteorite is a member of the Beta
Taurid meteor stream?
Trajectory data on the Richardton meteorite could be telling if it came from
the south west direction. And I have yet to find any observers that stated the
direction from which it came.

The Richardon meteorite, of which I have samples is very friable and even
though it fell a hundred and one years ago, it is the subject of much study
even today as it has isotopes that relate to having been close to the Sun, such
as what one would expect of the parent body of the Beta Taurids.... Comet
Encke. At the end of this month Earth will be in the Encke Beta Taurid meteor
stream and astronomers will be studying it to determine if it has masses large
enough to create a Tunguska event. And if so, there certainly will be smaller
masses that could produce meteorites such as Richardton which fell on June 30th
1918. In fact any meteorite that fell on or around June 30th coming from the
south west direction should be further examined to see if they have isotopic
properties that one would expect having been close to the Sun.

C'est pas inintéressant, au moins à titre de réflexion.

Mais pour moi l'isotopie n'est pas suffisante pour faire un lien sur un corps parent aussi formellement identifié, seule la trajectoire permettrait d'en avoir une idée plus précise et d'avancer ...

tout à fait d'accord avec toi Vivien
mais cette hypothèse est séduisante, voire trop belle

Un peu trop belle à mon gout ... surtout à notre époque d'intox "journalistique" on l'on te fait un gros titre de "fin du monde" avec trois fois rien !

Comme là dit le grand Carl : des affirmations extraordinaires nécessitent des preuves extraordinaires !
