Click here for the original version of this pseudo-MPEC, or here for information on the 2020 August 29 re-entry of the object over Tahiti.
TLEs are available for this object (obviously, of historical interest only at this point!) and for some of the other objects on these pages. Space-Track provided TLEs for it until early 2018; when they stopped, I began providing TLEs and did so until it re-entered.
