Hi All, Each time a pair of falls occurs at roughly the same geographic location on approximately the same calendar date (in different years), I suppose it is only human nature to try to assign some cause to the synchronicity. But fall location duplication can be quickly dismissed as random chance, since there is no connection between earth-crossing asteroid orbital periods and earth's rotational period. However, date-synchronized falls ~is~ a possibility. Dr. Rubin and I wrote a paper on this subject which appeared in the journal _Earth, Moon and Planets_ in April 2008: <http://www.springerlink.com/content/fh155p1n30318876/?p=c33955927db24de 2b0c2116738abeb6d&pi=0> Our conclusion was that due to the tiny fraction of meteorite falls that are successfully recovered each year, and the comparatively short dynamical lifetime of a meteoroid stream (10^4 to 10^5 a), the probability of successful recovery of two falls from the same stream are extremely small. --Rob -----Original Message----- From: [email protected] on behalf of [email protected] Sent: Sun 11/15/2009 12:20 PM To: [email protected] Subject: Re: [meteorite-list] new fall RICH friday 13 / 11/2009; ; 21.25 cmt could there be a "cloud" of objects that Earth's orbit flys through?
