This is the bow wave which we see as a cross section of  a cone.  It is the 
front boundary of  a zone of compression twixt the bow wave and the surface of 
the 

meteor.  The green color is from atmospheric oxygen being heated to the point 
of 

emitting its spectra bands which when combined together  appears as green light

The wave is usually too faint for a camera to pick up  I'd love a link.
