The Jupiter Anchor 877 Harmonic Bridge Synchronization of the 3I ATLAS Relay Node.

Abstract: This paper presents a pre-registered harmonic prediction for the interstellar object 3I/ATLAS associated with its close approach to Jupiter on March 16, 2026. Prior to perihelion, observations indicated a characteristic rotational or wobble period of approximately 7.75 hours, which transitioned to 7.14 hours post-perihelion alongside a persistent three-jet morphology separated by roughly 120 degrees. Using an empirical ratio ($R \approx 1.085$) derived from this shift, a subsequent stable harmonic state near 6.58 hours is predicted to emerge abruptly. Alternatively, a secondary geometry-locked resonance near 5.9–6.0 hours may manifest due to structural coupling with the triple-jet configuration. The timing of this transition is predicted to coincide strictly with the object's traversal of Jupiter's Hill sphere boundary ($\approx 53.4\text{ million kilometers}$) rather than evolving gradually with heliocentric distance, providing explicit, time-bounded criteria for confirmation or falsification.
