Spörer (crater)

Spörer is a lunar crater that lies just to the north of Herschel crater, and southeast of the lava-flooded Flammarion crater. To the southeast is Gyldén crater, and to the northeast is Réaumur crater.

The floor of this crater has been flooded with basaltic-lava, leaving only a shallow rim above the surface. The narrow rim is roughly circular but irregular and broken in several locations. The rim has a slight outward bulge to the northwest. The interior of the crater is level and featureless.

Satellite craters

By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to Spörer crater.
