‘This won’t be subtle’: SpaceX West Coast launch will create sonic boom

Most likely this is related to the SpaceX's Falcon 9 rocket which launched around 7:30 p.m. Once again, the light is from a SpaceX launch.

We'd love to see any photos that you managed to get. Previous re-capture missions from Vandenberg have landed the rocket on a barge floating in the Pacific Ocean, about 400 miles out to sea.

The rocket being used in Sunday's mission was previously employed in a June launch.

SpaceX founder Elon Musk was a bit more succinct in a pre-launch tweet: "Sonic boom warning". It will mark the first time the innovative company has attempted a ground landing at Vandenberg.

SpaceX calls its California touchdown site Landing Zone 4, presumably because it's part of Vandenberg's Space Launch Complex 4 (SLC-4).

The satellite is the first of two for Argentina's space agency.

SAOCOM-1A's radar measurements will track soil-moisture levels, thereby aiding forecasts of crop yields.

Two minutes later, the second stage engine shut down as planned and two-and-a-half minutes after that, the SAOCOM 1A satellite was released into the planned polar orbit. Both spacecraft will make similar observations from orbit, which will be integrated with measurements made by a network of Italian satellites. The satellite is created to provide radar imagery to help emergency responders and monitor the environment, including the collection of soil moisture measurements.

"SAOCOM" is short for "Satélite Argentino de Observación Con Microondas", which is Spanish for "Argentine Microwave-Observation Satellite".
