Can I see it from here?

The launch time isn't precise enough yet for a sky forecast.

Estimates from a typical ascent toward the likely orbit. Real trajectories, cloud and haze vary; the farther away, the lower and shorter the view.

Mission

Amazon Leo, formerly known as Project Kuiper, is a mega constellation of satellites in Low Earth Orbit that will offer broadband internet access, this constellation will be managed by Kuiper Systems LLC, a subsidiary of Amazon. This constellation is planned to be composed of 3,276 satellites. The satellites are projected to be placed in 98 orbital planes in three orbital layers, one at 590 km, 610 km and 630 km altitude. 35-40 satellites will be carried on each Ariane 6 launch.
