西科尔斯基环形山(Sikorsky)是位于月球背面南半部一座古老的大撞击坑，约形成于39.2-38.5亿年前的酒海纪[1]，其名称取自俄裔美籍航空先驱，著名飞机和直升机设计师伊戈尔·伊万诺维奇·西科尔斯基(1889年－1972年)，1979年被国际天文学联合会批准接受。

描述

该环形山位于从地球上看不到的月球东南侧边沿后。西北靠近小陨石坑莫尔顿环形山、西南毗邻韦克斯勒环形山、东南方则坐落了被广袤平原包围着的薛定谔环形山[2]。该陨坑中心月面坐标为65°53′S 103°39′E / 65.89°S 103.65°E / -65.89; 103.65，直径97.67公里[3]，深度约2.85公里[1]。

1967年月球轨道器4号拍摄了这一地区的高清照片，在西科斯基环形山中间发现了一条贯穿其中长达310公里的切沟。因该线状特征正对着向薛定谔环形山，并因此被命名为薛定谔月谷。

西科尔斯基环形山本身已严重侵蚀，其边缘也已磨损，其中东北侧几乎已完全损毁，而西侧被一座较小但更古老的陨石坑所环绕，除薛定谔月谷外，还有一条较小的裂隙从东南方切入到陨坑的东侧边缘，沿环形山的东、东北和西北边沿分布着一些较小的陨石坑。

西科尔斯基环形山被薛定谔月谷一分为二，坑内地表相对平坦而无特色，稀疏地点缀着少量更小的陨坑；在靠近中心点附近，是一座外形几乎呈完美碗状的卫星陨石坑-"西科尔斯基 Q"，它从西侧切入进薛定谔月谷中。

卫星陨石坑

按惯例，通过在最靠近西科尔斯基环形山的卫星陨坑中心点旁放置字母，以在月图上标示它们。

Llwyngwern railway station

Former railway station in Wales Llwyngwern was a station on the Corris Railway in Wales, built to serve the hamlet of Pantperthog and the residents of Plas Llwyngwern, a house where a daughter of the 5th Marquess of Londonderry lived with her husband. Although the Plas was in Montgomeryshire, the station was across the Afon Dulas in Merionethshire. The station was built at Llwyngwern, rather than at Pantperthog, because there is a very tight bend and a steep gradient on the railway at Pantper...
