Falcon Heavy | USSF-75 visibility range: each ring marks how far away the rocket is above the horizon that many seconds after liftoff, out to about 305 miles at T+90s. Rings are line-of-sight geometry from a representative ascent profile, centered on the pad — the rocket also travels downrange, stretching views along its track, and night launches are often visible well beyond the outer ring. Assumes clear skies and an open horizon.

Where to look

A rocket lifts off below the horizon for distant viewers, then climbs into view as it gains altitude and flies downrange. Closer to the pad you'll see it within seconds; a few hundred miles away it can take three to six minutes to rise over the horizon. Find an open view in the direction shown for your city and start watching at liftoff.
