SatEvo decay list #75 (issued 1999 April 19)
This list of my satellite decay (re-entry) predictions and analyses is posted to the SeeSat-L mailing list and to the Usenet newsgroup sci.astro.satellites.visual-observe.
The "Actual?" decay dates are my estimates based on the published orbital element sets ("elsets") over the object's final days. Objects are included in the "Predicted" column if I anticipate their decay by 1999 June 15, although some larger and/or more interesting decayers are included beyond that date.
