3I/ATLAS (C/2025 N1) — Outbound Baryonic-Matter Prediction Record III (2025-11-23 to 2026-06-01)

This dataset presents the Outbound Baryonic-Matter Prediction Record III for the interstellar object 3I/ATLAS (C/2025 N1), covering the period from 2025-11-23 to 2026-06-01 as the object travels away from the Sun after perihelion. Using JPL Horizons as the reference gravitational ephemeris, this work provides a fully pre-registered series of predicted astrometric and kinematic deviations (ΔRA, ΔDec, Δv) derived from the Konkle Baryonic-Matter Physics Framework.Building on the author’s earlier inbound and perihelion studies (Figshare DOIs: 29936516, 30335635, 30510980, 30511304, 30546008, 30556721, 30661226), this Record III expands the analysis into the outbound phase, identifying four discrete Baryonic-Matter corridor crossings where measurable departures from the JPL gravity-plus-outgassing model are expected. These include:Solar BM Relaxation following perihelion (late November 2025)Earth-aligned BM corridor near closest approach (2025-12-19)Outbound angle-shift corridor as 3I/ATLAS exits the inner solar compression well (January 2026)Jovian BM compression layer crossing near Jupiter’s closest approach (2026-03-16), predicted to generate the strongest measurable deviationThe dataset provides testable BM predictions, including angular shifts of 0.2–0.5 arcsec, velocity deviations of ~1 m/s, a forecasted widening of the Earth-distance on 2025-12-19 by 0.001–0.005 AU, and a projected 10,000-km positional offset during the Jovian corridor event.All predictions are presented prior to observation and are not tuned to residuals. The accompanying table lists the JPL-based reference distances and approximate velocities, alongside the Baryonic-Matter deviation forecasts and their corresponding field-layer classifications.This record forms part of the author’s larger Baryonic-Matter Physics initiative, complementing the upcoming four-volume Baryonic-Matter Physics Quartet and supported by two books currently in print: The Fall of Shadows and Structure at All Scales. It is intended as a transparent scientific benchmark for evaluating deterministic Baryonic-Matter theory against traditional gravitational modeling as new astrometric reductions become available.
