Brightness Characterization and Modeling for Amazon Leo Satellites

Instrumentation and Methods for Astrophysics 2026-01-13 v1

Abstract

The mean apparent magnitude of Amazon Leo satellites is 6.28 based on 1,938 observations. For spacecraft in their operational mode, 92% exceeded the brightness limit recommended by the IAU for interference with research, while 25% distract from aesthetic appreciation of the night sky. The reflective characteristics are similar to Version 1 Starlink spacecraft.
