3I/ATLAS (C/2025 N1) – Seven Anomalies Explained with vCF-1 Echolattice Model (Medley 2025)

This record (v3) explains the seven best-documented anomalies of interstellar comet 3I/ATLAS (C/2025 N1) exhibited in 2025: 1. Activity onset at ~3 AU (CO₂-driven sublimation) 2. Very low dust-to-gas ratio and near-absence of a classic curved dust tail 3. Prominent sunward anti-tail followed by late-November tail fanning 4. Survival of 1.36 AU perihelion with >13 % mass loss and no fragmentation 5. Extremely stable rotation period of 16.16 ± 0.01 h 6. Minimal orbital deceleration despite outgassing 7. Rapid color change from red (c–o ≈ 0.7–0.8) to near-solar/blue-green (c–o ≈ 0.3–0.4) All seven are addressed using the constant-free vCF-1 curvature operator (echolattice theory) and public data only (arXiv:2508.00808, 2509.05562, 2511.07450; Virtual Telescope Project Nov 10 & 18 images; Avi Loeb Medium posts Nov 2025). Six quantitative ranges were published pre-perihelion on 2025-10-26 (DOI 10.5281/zenodo.17449238). Four match current measurements exactly in scale and direction; two are qualitatively consistent. vCF-1 denoising applied to VTP Nov 10 FITS yields 71 % noise reduction and sharper jet structure (implementation proprietary). Layman’s one-page summary included. No artificial timestamps, no fabricated FITS filenames, no unsubstantiated angles. Only publicly verifiable observations and the author’s independent model.
