Remarks A powerful and clear green shooting star withe dust-like tail glittering a couple of seconds after it itself burned out. I listened for a sound but I didn't hear anything. If this had been an airplane it would have been flying along the northwestern coast of Sealand (like Gilleleje to Hundested) if seen from the direction of Vedbæk - I had just prior to this experience tracked LH2432 from MUC to GOT at 10.000 m altitude over Tisvildeleje; and the fireball came in around the direction of Tisvildeleje but higher up than the airplane had been and ended in the direction of Hundested just above the treeline. I was doing astrophotography when it happened but I was aiming at M51 så just a little to high in the sky unfortunately ;-)
