Second trio ... it is a well-known expression for hockey fans. For amateur astronomers who photographed the Moon, it may have another meaning as some craters are often photographed in trio. In this picture, we can see a popular trio on the left, on the terminator. Another trio is visible on the right, in an area that was more illuminated. I identified these six craters on the duplicate image on the right. On the bottom picture, Arzachel is in the upper left corner of the image. One can enjoy its 1000-meters slopes and its central peak (1500 meters), which generates a long shadow.
