[Launch Alert] Tuesday Evening Launch

[Launch Alert]

A Falcon 9 rocket is scheduled for launch Tuesday evening (June 18) from Vandenberg SFB, Calif. The vehicle is slated to lift off from south base between 8:00 p.m. and midnight PDT and carry several Starlink satellites into orbit. Following launch, the Falcon 9 will probably fly towards the southeast and roughly parallel the coast.

If liftoff occurs at the start of the window, the Sun will be above the horizon for many places near the coast, severely impacting launch visibility. However, for venues further east, the launch window opens during evening twilight. This could result in the Falcon's exhaust plume being illuminated by the Sun at high altitude while being suspended in a twilight sky.

If the launch is delayed, observers near the coast may also be treated to the Twilight Effect.

Following liftoff, the first stage is scheduled to land on a drone ship downrange.
