Satellites making up China's 'Thousand Sails' found to be exceeding brightness limits

A team of space researchers with the IAU Center for the Protection of Dark and Quiet Skies from Satellite Constellation Interference, working with a colleague from Belgian Working Group Satellites, has found that the satellites making up China's "Thousand Sails" project exceed brightness limits that have been proposed by astronomical groups wanting to prevent satellites from blocking the view to space. The paper describing their findings is posted to the arXiv preprint server.
