Derek, thank you for posting the link to the recent article in Nature on the tentative identification of WT1190F:

http://www.nature.com/news/falling-space-debris-traced-to-1998-lunar-mission-1.19162?WT.mc_id=SFB_NNEWS_1508_RHBox

I have revised my table of satellite re-entry sightings to reflect the emerging consensus that it was the TLI
(translunar insertion stage) of Lunar Prospector, as reported in Nature. Since it is not yet proven, I refer to this as
the suspected identity.

Based on information in the mission handbook (URL below), I estimate that the empty mass of the object was about 200 kg,
which consisted mostly of its Star 37FM solid rocket motor, and payload adaptor.
