        The density of observing stations was very high all along the path, especially in western  part of  Czech republic and  in Germany.

        Dispersion in the timing results give only a relative precision in the asteroid motion direction. The path position can be fixed laterally with a precision better than one kilometre,

        revealing a slight shift (0.4 path width) toward south relative to the last predictions. The path ran over Russia, common border of Latvia, Lithuania and Belarus, Poland,

        Czech republic, southern part of Germany, France,  Spain and Portugal.

         “Shepherd” observers (who missed the path by the shortest distance) on the northern border are DBU, GHD and BDR. On the southern side, the “shepherd” observers are ISG and LXP.

        MKM was in the real path but missed the event.

 

        Despite the scattering, chords can be fitted with an elongated, 170 X 130 km elliptic profile, with the long axis approximately parallel to the asteroid motion. These dimensions are

        to be compared with the 146 km previously estimated diameter.

        Please send the reports about positive as well as negative observations ! Negative reports can be decisive to determine the shape or refine the orbit of the asteroid, as has just been

        shown in the case of Bertholda.
