‘This Is Not Cool!’ – Astronomers Despair As SpaceX Starlink Train Ruins Observation Of Nearby Galaxies

TL:DR: affected but not ruined.  Possibly fixable in software.  And the affected observations were within 90ish minutes of when telescoping would have been stopped due to rising sun.  So maybe asrronomy just loses 3 hours of observation time a night (satellites shine by reflected sunlight, which can only occur ~90 mins after/before sunset/sunrise)?  But still will have occulations even during dark time.

Why SpaceX is Making Starlink – YouTube

November 25th, 2019 No comments

Good explainer on Starlink. Especially about the expected revenue in the last few minutes. And that retail cost (~40$US) will be possible due to bigly revenue expected from time-sensitive hi speed traders.

Second set of 60 were launched last week. The trail is visible in the mornings (e.e tomorrow, 26th, starting at ~5:28am to ~6:19am, look NW approx 45degrees up from horizon, a.k.a 1/2way up to overhead).  About as bright as the stars in the Big Dipper.

On the downside, StarLink has already affected (but not ruined) a serious astronomy observation
