The decaying NOSS 2-3 Titan 4 rocket has been declassified. As Vladimir
Agapov suggested here on February 17, the object is catalogued as #23863
= 96- 29 G, and not as #23907 = 96- 29 B. The first elset for this
appeared on OIG's database at ~13h UTC today following the issue of its
first SpaceCom decay notice.

Note: I'm still investigating SatEvo's poor prediction of yesterday.
SpaceCom and Harro called this much better. Like SpaceCom, I believe
that this decayed near a southbound equator crossing between Somalia and
the Seychelles.
