    "abstract": "The relativity of simultaneity implies that the image of a Lorentz\ntransformed (LT) spherical (circular) wavefront is not a spherical (circular)\nwavefront (Einstein 1905) but an ellipsoidal (elliptical) wavefront (Moreau,\nAm.J.of Phys).We show firstly that the relativity of simultaneity leads to the\nconsequence that the image of a Lorentz transformed plane wavefront is a\ntangent plane to an ellipsoid and not a tangent plane to a sphere (Einstein\n1905). We deduce then a longitudinal component of the tangent vector to\nPoincare\u0027s ellipse which is directly connected to the relativity of\nsimultaneity. We suggest finally that this violation of relativity of\nsimultaneity is related to Einstein\u0027s implicit choice of the (non relativistic)\ntransverse gauge in his theory of (rigid) wavefronts.",
