Comprehensive coverage

The BlueWalker 3 satellite imaged from the ground on April 3, 2023. The optical brightness of the 8-by-8-meter satellite – one of the brightest objects in the night sky that reached a peak brightness of magnitude 0.4 – is shown here as it passes against the starry background. For comparison, two fainter satellites can also be seen in the photo; Starlink-4781 (ahead of BlueWalker) and Starlink-4016 (simultaneous and slightly behind BlueWalker by a few frames).
