@ramsey@phpc.social @sundogplanets@mastodon.social The simulation was specifically done over the VLT, but a similar increase would be visible at other locations. Even if the mirrors aren't pointing directly at the observer, when seen sideways they would still be as luminous as a bright planet like Venus. With a swarm of these bright sources above you at any given time, the atmosphere would scatter their light around, leading to the overall increase in brightness you see here.
