Sp Rer (Crater)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Spörer is a lunar crater that lies just to the north of the crater Herschel, and southeast of the lava-flooded Flammarion. To the southeast is Gyldén, and to the northeast is Réaumur. 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.
