Residents across the Southwest experienced an unexpected light show yesterday evening as a SpaceX rocket carved a luminous path through the twilight sky, a spectacle visible from Arizona and beyond. According to a report from AZFamily, the visual marvel, dubbed the "twilight effect," was the result of a Falcon 9 rocket launch from Vandenberg Space Force Base, carrying a payload of 28 Starlink satellites into orbit.

Launching just after 7 p.m., the rocket's first stage booster, marking its 28th flight, drew eyes skyward, with its exhaust plume illuminated by the sun's residual light, creating a comet-like appearance in the early evening sky. As is custom for SpaceX, following stage separation, the first stage was expected to touch down on the "Of Course I Still Love You" droneship positioned in the Pacific Ocean, CBS 8 reported.

This recent celestial display mirrors a similar occurrence in July, captivating onlookers with its unique atmospheric conditions which allow for such a visual phenomenon. Residents in counties including Santa Barbara, San Luis Obispo, and Ventura may have also experienced sonic booms associated with the launch, adding an auditory component to the event.

The liftoff was meticulously scheduled for 6:28 p.m. PT with SpaceX opening its launch window until 8:32 p.m., however, the inherent uncertainties in rocket launches such as climatic shifts or technical abnormalities can lead to changes in timing, which did not occur in this instance. SpaceX aficionados and space enthusiasts could tune into a live webcast hosted about five minutes prior to liftoff on the company's website, offering a front-row seat to those unable to witness the launch firsthand.
