AST SpaceMobile satellites measured far brighter than targets

Astronomers report that measurements of AST SpaceMobile satellites show an average brightness seven times above the mitigation targets cited in the company's FCC filings, with peak values more than 200 times brighter than the International Astronomical Union's recommended limit of magnitude 7. Observers warn the company is expected to deploy more satellites, raising concerns about interference with ground-based astronomy.
Why now: Concerns are growing over light pollution from a rapidly expanding satellite constellation and its impact on astronomy.
