[Launch Alert] Monday Evening Launch (reformatted)

[Launch Alert]

This evening's (April 1) launch of a Falcon 9 rocket from Vandenberg SFB, Calif. appears to be on schedule. The vehicle is slated to leave south base between 7:30 and 11:30 p.m. PDT.

If liftoff occurs early in the launch window, observers as far away as Sonoma, Reno, southern Colorado, southern Utah, New Mexico, El Paso, and western Mexico may be treated to an interesting display as the rocket's exhaust is illuminated by the Sun at high altitude with a dusk or dark sky background.

If the Falcon 9 lifts off later, the event could still be visible to the unaided eye for hundreds of miles, but the exhaust plume will be much less pronounced.

Observers within 25 miles of the coast between La Conchita and Zuma Beach may hear a sonic boom and distant rumble from the launch several minutes after liftoff.
