Can I see it from here?

Night launch: visible as a bright moving light from far away if it's clear.

Computed on your device; your location never leaves it.

None of the major cities we track have a good view; it's visible mainly near the pad.

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