Extended Data Fig. 5: Surface brightness magnitude of the satellite trails per exposure vs. distance to the satellite.
From: Satellite megaconstellations will threaten space-based astronomy
Surface brightness magnitude of the satellite trails per simulated exposure as a function of the distance to the detected satellite. Left to right, top to bottom: a) Hubble Space Telescope, b) SPHEREx, c) ARRAKIHS, d) Xuntian Space Telescope. The colorbar represents the width of the satellite trail as detected on each telescope (in arcsec). Surface brigthness magnitudes were measured at the center of the spectral range of each telescope (see Table 2). Upward triangles and circles represent trails generated by satellites illuminated and non-illuminated by the Sun. Yellow star: Observed surface brightness and estimated distance of the satellite trail in Hubble Space Telescope, estimated from the WFC3/UVIS F350LP observation of Starlink 1619.
