TL;DR
This paper analyzes the brightness characteristics of OneWeb satellites using 80,000 visible light measurements, providing insights into their illumination behavior, variability, and implications for observation planning.
Contribution
It offers the first large-scale characterization of OneWeb satellite brightness and develops tools to minimize observational interference.
Findings
Mean apparent magnitude reported for OneWeb satellites
Illumination phase function differs from VisorSat spacecraft
Brightness flares and magnitude variation rates characterized
Abstract
The mean apparent magnitude and the mean of magnitudes adjusted to a standard distance are reported. The illumination phase function for OneWeb satellites is determined and it differs strongly from that of VisorSat spacecraft. Brightness flares are characterized and the mean rate of magnitude variation during a pass is determined. Tools for planning observations that minimize interference from bright satellites are illustrated and discussed.
