The Apollo 12 landing site lies within the Moon’s huge Oceanus Procellarum, the Ocean of Storms. Because this feature covers 812,000 square miles (2.1 million square km), we need to refine our search a bit. First, locate Lansberg Crater, then find the triangular group of craters to its lower right. The landing site lies midway between Lansberg and the largest of the triad. This region is visible 10 through 24 days past New Moon.
