Small (9×5 km) crater Schrödinger G inside large crater <a href="https://en.wikipedia.org/wiki/Schr%C3%B6dinger_(crater)" class="extiw" title="en:Schrödinger (crater)">Schrödinger</a>. It is interpreted as volcanic crater (<a rel="nofollow" class="external text" href="https://dx.doi.org/10.1016%2Fj.icarus.2012.11.008">Kramer et al., 2013</a>). Mosaic of photos by <a href="https://en.wikipedia.org/wiki/Lunar_Reconnaissance_Orbiter" class="extiw" title="en:Lunar Reconnaissance Orbiter">Lunar Reconnaissance Orbiter</a>, made with Narrow Angle Camera. Right and middle part is made of photos <a rel="nofollow" class="external text" href="http://wms.lroc.asu.edu/lroc/view_lroc/LRO-L-LROC-2-EDR-V1.0/M110691019LE">M110691019LE</a> and <a rel="nofollow" class="external text" href="http://wms.lroc.asu.edu/lroc/view_lroc/LRO-L-LROC-2-EDR-V1.0/M110691019RE">M110691019RE</a> (taken simultaneously, so, they can be aligned perfectly).

First two photos were taken 20 October 2009, third one — 10 October 2010. Sun elevation in both cases is about 16°. Height of the image is about 10 km, north is up.
