Overview
- An arXiv preprint analyzing about 2,000 observations reports an average magnitude of 6.28 for Amazon’s Leo satellites, with 92% surpassing the International Astronomical Union’s research brightness threshold.
- Roughly 25% of recorded passes were bright enough to be seen by eye under some conditions, with astronomers noting image streaks and artifacts during twilight observations.
- The current fleet orbits near 630 kilometers, and FCC approvals for future operations at approximately 590 and 610 kilometers could make the satellites appear brighter.
- Amazon says it is working with the astronomy community under a National Science Foundation agreement, testing dark coatings and attitude adjustments to reduce reflectivity and flares.
- About 180 satellites are currently in orbit toward a planned constellation of roughly 3,232, with service expected after 578 are deployed and a licensing requirement to launch half the system by July 30, 2026.
