2008 TC3 moved from a geodetic longitude of 31.80381° E and latitude of +20.85787° N at 50 km altitude, to 32.58481° E, +20.70569° N at 20 km altitude above the WGS-84 ellipsoid. White arrow represents the path of the 2008 TC3 fireball with the projected, non-decelerating ground path represented as a thin black line (altitude labels in km, within white ovals). The sizes of the red symbols indicate small (1–10 g), medium (10–100 g) and large (100–1,000 g) meteorites. Our dark-flight calculations show that 270-g fragments would have stopped ablating at around 32 km altitude, falling vertically on the ground at 30–60 m s-1. Labels in white rectangles mark the position where meteorites of indicated masses are predicted to have fallen (calculations assume spheres released at 12.4 km s-1 from detonation at 37 km altitude, white star). In light yellow is shown the area that was systematically searched. Special attention was given to possible large fragments further down track, but none were found. Such larger masses would have carried residual forward velocity. The yellow line marks the path of the local train tracks with the location of Station 6 labelled.
