# Starlink 3684 Starlink 3684 is the spacecraft record associated in the notebook with NORAD catalog number 52124. ## Notebook evidence PDF page 17 of [[Scanned_20260730-1913]] records “Starlink 3684,” “NORAD 52124,” low Earth orbit, and an approximately eleven-month note. External orbital records cited by the reconstruction identify a March 19, 2022 launch and January 4, 2025 decay. ## Archival significance The catalog number is the durable identity key. Names can be duplicated or reformatted, while the catalog identifier permits the observation to be linked to orbital history even after reentry. This mirrors the notebook's broader interest in stable identifiers and [[Control-Plane Continuity]]. ## Boundary The page establishes tracking or research interest. It does not establish ownership, communication with the spacecraft, or a relationship to Starlink operations. ## Relationships [[Starlink]] · [[NORAD Satellite Catalog]] · [[Low Earth Orbit]] ## Source - [[Scanned_20260730-1913]], PDF page 17 and its cited orbital records.
