    Abstract:Observed magnitudes of Qianfan spacecraft range from 4
    when they are near zenith to 8 when low in the sky. Nearly all of
    the observations can be modeled with a nadir-facing flat antenna
    panel and the underside of a zenith-facing solar array, both with
    Lambertian reflectance properties. These satellites will impact
    astronomical research unless their brightness is reduced.
