The Flamsteed K region is in the southern part of Oceanus Procellarum, approximately 60 km (kilometers) north of the crater Flamsteed and 330 km southwest of the crater Kepler. The region was photographed by Lunar Orbiters I and III; it includes the landing site of Surveyor I and a potential early Apollo landing site. The area is included in a 1:1,000,000-scale map by Marshall (1962).
