# A Sign-Stable Earth-Fixed Modulation in Earth Flyby Anomalies

M. Fikret Yalcinbas, 2026. _Preprints.org_.

Builds an Earth-fixed coupling proxy from distance-weighted surface visibility over a land-sea mask and finds a stable sign structure across the flybys, interpreted as a modulation of the Anderson prediction.
