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
