Hi you all,

Pavol is totally right! Christou & Beurle, and later Selsis et al. 
published some articles about the probable meteor shower on Mars. The 
radiant is theoritical, not observed of course. The fact is, if you take 
the observed meteor, the chances for it to be aligned with the 
theoritical radiant are less than 10%.
About the speed: the exposure time and the lenght of the streak shows 
this was a slow meteor, and the expected entry velocity for Martian 
Cepheids is 11 km/s.
We called them "Cepheids" because, from calculations (again!), the 
radiant of the meteor shower caused by comet 114P/Wisemann-Skiff is 
located is Cepheus.

Hope this helps :-)

Jeremie
