Based on just that initial batch, he estimated that at a latitude of 52 degrees north (about where London is located), there will be 84 Starlink satellites above the horizon at all times. And for many hours around dusk, dawn, and in the nighttime during summer, 15 of those satellites would be visible in the sky at all times, about 30 degrees above the horizon."
