Zelimir,

The paper below is estimating what could possibly have hit the ground, right? TKW is an estimate or sometimes an exact weight of what has actually been found. These two are potentially very different numbers.

So, it is not the TKW that should be updated. Can you clarify?

Regards,

Hello Linton,

Many thanks for the "Meteorite picture of the day" (Mbale).

Regarding the TKW (officially 850+_at_~150+ kg), here is a more recent update:

The TKW officially reported was recently re-evaluated (O. Popova, in: Proc. Meteoroids 2010?, Breckenridge, Co, July 2011, pp 232-254).
The paper reports, among others, that the progressive fragmentation model to the Mbale entry allowed estimation of fallen mass as 200-250 kg in 100-3000 fragments (in dependence on assumed breakup model) covering a strewnfield of about 1 x 7-9 km.

Best wishes,

Zelimir
