A launch from Vandenberg, seen from Miami

From Miami, Vandenberg SFB is about 3977 km away. Face WNW (roughly 294°) shortly after liftoff and watch low on the horizon — the rocket climbs as it heads downrange.

You're not watching the rocket itself — beyond a few km the vehicle is far too small to see. What's visible is the engine plume at 65–100+ km altitude: at night a brilliant moving flame (routinely seen 300+ km away), at dawn/dusk a sunlit "jellyfish" cloud that has been documented 800+ km away, in daytime only a white contrail with much shorter range. Cloud cover, local horizon and trajectory all matter.
