RECLASSIFICATION

CATEGORY A · GEOLOGICAL

AMENDMENT NO: 22-C / 2147-B
FILED: DAY 94 · IN-SYSTEM
VESSEL: NV ERIKA MAGNUSDÓTTIR
JUNCTION: 22-C ("TWENTY-TWO CHARLTON")
SURVEY TARGET: 22-C-III · NORTHERN CONTINENT
EXTENT: APPROX. 400 KM²

1 · AMENDMENT

The survey designated Mission 22-C/2147 is hereby reclassified from Contact Survey · Tier 2 to Geological Anomaly Assessment · Category A. All on-site documentation, observation logs, instrument records, and crew assessments are to be filed against this revised classification.

Reclassification is consistent with the assessment provided by visiting geophysicist Dr. Liang Kim (Houston Institute of Planetary Sciences, 97.3% single-methodology confidence). Subsequent combined-methodology assessment is not material to the present classification.

2 · OBSERVED FEATURES

SITE AGE (RADIOMETRIC): ~80,000 – 200,000 years
SURFACE STRUCTURES: Compatible with mineral lattice formations under sustained gravitational compression
THERMODYNAMIC PROFILE: Locally irregular. Attributed to absent volcanism in planetary cooling phase.
COORDINATES (CENTROID): [REDACTED — INSTITUTIONAL ARCHIVE ACCESS REQUIRED]

3 · FILING INSTRUCTIONS

All crew observations are to be filed against the revised classification. Specifically:

  • Calibration logs to record drift readings only, without geological-classification annotations.
  • Visual surveys to be filed as planetary-feature documentation. No site-survey annotations are required for this classification.
  • ISCA notification is not required for Category A filings.
  • Mission record to indicate routine reclassification consistent with Dr. Kim's geological assessment.

4 · CHAIN OF AUTHORITY

Amendment authorised under SNG institutional liaison with ISNA Office of Vessel Operations. Vessel command is instructed to acknowledge by Day 96.
