Modifications of the ionosphere D layer density and/or altitude by solar UV or XR bursts are frequently observed. inducing phase and/or amplitude modifications on VLF transmissions propagation. A perturbation of the amplitude of french and german VLF transmissions received at Pic du Midi observatory during the Geminids 2010 meteor shower has been observed, which is triggered by a large meteor ionized trail
