Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Starlink satellites shine in the night sky because sunlight reflects off their reflective surfaces and solar panels, a phenomenon documented by astronomical photometry.

The analysis

The retrieved papers include studies on Starlink satellite photometry (e.g., Papers 2 and 4) which explicitly measure the sunlight reflected by the satellites' solar arrays, bus bodies, and visors. The other papers discuss general remote sensing, ozone, lake variables, or crop monitoring without refuting the optical mechanisms of Starlink visibility. Therefore, the claim is well-supported by the evidence.
