The parent post said that only observations at dusk and dawn are affected. I'm pointing out that, even at astronomical midnight, large fractions of the sky aren't in earth's shadow. For other wavelengths the shadow is irrelevant, since satellites contaminate data even without the sun's direct illumination.
- Robotbeat 5y agoWell sure, at high latitudes and during certain seasons that may be true for higher altitude LEO satellites (Starlink is fairly low), but if we’re talking corner cases, sometimes the surface of the Earth isn’t in Earth’s shadow at astronomical midnight (land of the midnight sun). Corner cases don’t really count as “frequent,” however.
