The location of Iczerone Stimson on the tactical situation monitor
Iczerone Stimson was a location in the Alpha Quadrant.
In 2367, Iczerone Stimson's was labeled on a tactical situation monitor in Captain Benjamin Maxwell's ready room on the USS Phoenix. (TNG: "The Wounded", okudagram)
In 2366, in an alternate timeline, during the Federation-Klingon War, Iczerone Stimson's position was labeled on a tactical situation monitor on the bridge and in the ready room of the USS Enterprise-D. (TNG: "Yesterday's Enterprise", okudagram)
This location was only mentioned in writing.
This location's quadrant of origin is inferred based on the position of neighboring locations – the Altair system (Altair III), Andor, Babel, Delta Vega, Eminiar, Janus VI, and Rigel – as seen in the star charts appearing in Star Trek VI: The Undiscovered Country and in the Star Trek: Picard episode "Maps and Legends".
The name seems to be, in part, a reference to production staff associate Mark Stimson. (citation needed • edit)
