Abstract
ABSTRACT We present the detection of false positive double-lined spectroscopic binaries candidates using medium-resolution survey spectra from the one time-domain field of Large Sky Area Multi-Object Fibre Spectroscopic Telescope data release 10. The secondary component in all these binaries has near zero radial velocity and solar-like spectral lines. Highly likely this is light from the semitransparent clouds illuminated by the full Moon. However we also suspect that partially this contamination can be caused by a solar light reflected from the surface of low-orbital artificial satellites launched in the beginning of 2022. We found several possible contaminant candidates using archival orbital data. We propose measures to reduce risk of such contamination for the future observations and methods to find it in archived ones.
