[Launch Alert] Wednesday Launch

[Launch Alert]

The following is an advisory from Vandenberg SFB:

"The U.S. Space Force has approved the launch of a SpaceX Falcon 9 rocket carrying the Starlink 15-23 mission to low-Earth orbit, Wednesday, Sept. 2, 2026, between 12:46 a.m. - 4:46 a.m. PT from Space Launch Complex 4 East (SLC-4E).

A moderate possibility exists that residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear a sonic boom during the launch. Depending on weather and location, this event may sound like an abrupt crack of thunder, according to prediction models.

A live webcast of this mission will begin about 10 minutes prior to liftoff, which you can watch at https://www.spacex.com/launches/sl-15-23 and on X @SpaceX."

If the sky is clear, the event could be visible over a wide area.

For a better view of the launch, use tripod-mounted binoculars or a spotting scope. An astronomical telescope with a low-power eyepiece will probably provide the best view.
