A rising light on the horizon: night launches only. Vandenberg twilight launches are why Los Angeles occasionally stops traffic: the exhaust plume lit by a sun below the horizon spreads across the whole western sky. Day launches are rarely visible from the basin.
Daytime launches are usually invisible from this distance. At night, watch for a bright, steady point climbing from the horizon in the direction shown, arcing over one to three minutes; twilight launches can paint the sky.
Look northwest, low on the horizon, for the first two minutes.
Dark-ish and elevated; twilight and night launches only.
Ocean Avenue / Surf Beach for a real pad view.

A rising light on the horizon: night launches only. Los Angeles is about 141 miles (227 km) from SLC-4E, Vandenberg SFB, bearing 287° (WNW). Daytime launches are usually invisible from this distance. At night, watch for a bright, steady point climbing from the horizon in the direction shown, arcing over one to three minutes; twilight launches can paint the sky.
Face WNW (287°) toward Vandenberg. The rocket rises from that point on the horizon and arcs downrange: for Vandenberg launches that generally means south or southwest over the Pacific.
Two to three minutes for the first stage, sometimes longer at night when the second-stage plume is sunlit. Twilight launches, just after sunset or before sunrise, produce the biggest, longest-lasting displays.
