Hi Mendy,
You are perfectly right, this is not an exact weight (200-250 kg is
indeed just a range). I don't have that paper but this is part of the
summary I got. But it is clear that this figure is just deriving from
a (here "breakup") model.
I am sorry for my misleading word "update". By this, I meant this
should perhaps be added as a side remark to the writeup for Mbale,
which I did in my own catalog, understanding that I maintained the
official tkw and the number of pieces really collected (or at least
reported).
Sorry for the confusion. Excellent remark though.
Regards,
Zelimir

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?

Mendy Ouzillou

Hello Linton,
Many thanks for the "Meteorite picture of the day" (Mbale).
Regarding the TKW (officially 850+@~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
