Bright meteors often leave luminous trains along their tracks. If they last
several seconds or even minutes they are called persistent trains. See an example
of an evolving train of a Quadrantid meteor
here!
The photography was taken from the border of the "Steinheimer Becken",
a 15 Mio. year old impact crater in southern Germany.
The hill in the center is the central
mountain remaining from the impact. The circular crater wall has a diameter of
3.8 km. The opposite part can be seen behind the central hill.
Simultaneously to the origin of Steinheimer Becken a larger meteorite hit
the ground and created todays Nördlinger Ries, which is just
40 km far from Steinheim. The Meteor seen above had just a typical size of
a sand grain and was ablated by friction into dust in the atmosphere.
