[Launch Alert] Sunday Launch

[Launch Alert]

The following is an advisory from SpaceX:

"SpaceX is targeting Sunday, January 11 for Falcon 9's launch of the Twilight mission to dusk-dawn sun-synchronous orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California. The 57-minute launch window opens at 5:19 a.m. PT. If needed, there is a backup opportunity on Monday, January 12 with the same window.

About eight minutes after liftoff, Falcon 9's first stage will land on SpaceX's Landing Zone 4 (LZ-4) at Vandenberg Space Force Base, California. There is the possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the landing, but what residents experience will depend on weather and other conditions.

SpaceX's live webcast will begin approximately 15 minutes before Falcon 9's liftoff at spacex.com/launches."

Weather permitting this event could be visible to the unaided eye over a wide area.
