Hi folks,

Same day but not same year:

TREIMAN A.H. (1992) Fall days of the SNC meteorites: Evidence for an SNC
meteoroid stream, and a common site of origin (Meteoritics 27-1, 1992, 93-95):

Abstract-Four of the SNC meteorites of putative Martian origin are falls. Two of these fell on October 3: Chassigny in 1815 and Zagami in 1962. The probability of this coincidence arising from random fall days is approximately 1 in 60. If this coincidence is not the result of chance, it suggests that some of the SNC meteorites are derived from a meteoroid stream. In that Chassigny and Zagami span nearly the full range of SNC lithologies and histories, the coincidence of fall days is consistent with suggestions that all of the SNCs came from a single site (impact crater) on their parent planet.

Cheers,

Bernd
