Re: [meteorite-list] Chelyabinsk 1.8 kg mass found - 105 year period?

Hi Martin,

Thanks for this link:

 source: http://rt.com/news/meteorite-rush-biggest-fragment-404/

in which someone commented:

  Every 105 years? 1803 L'Aigle, 1908 Tungusta, 2013 Chelyabinsk, 2118?

Being a meteorite newbie I didn't recognise the first reference, but found:

 http://en.wikipedia.org/wiki/L%27Aigle_%28meteorite%29

In the early afternoon of 26 April 1803 a meteorite shower of
more than 3000 fragments fell upon the town of L'Aigle in Normandy
(France).

. . .

The L'Aigle event was a real milestone in the understanding of
meteorites and their origins because at that time the mere
existence of meteorites was harshly debated, if they were
recognised their origin was controversial, with most commentators
agreeing with Aristotle that they were terrestrial, and witnessed
meteorite falls were treated with great skepticism.

It is a L6 type ordinary chondrite.
