R1: Sulpicious Gallus was located on the SW shore of Mare Serenitatis. Dorsum Buckland and Dorsum von Cotta were located north of the crater on the mare floor.
R2: The larger crater Menelaus is southeast. It has a central peak or raised area. Rim was well lit and half of floor in shadow.

C1: The shadows of Dorsa Owen and Dorsa Gast on the west shore of Mare Serenitatis were barely visible between the shore and Dorsum von Cotta. Rimae Menelaus could just be seen - Menelaus to the east and Tacquet in the west.  Rimae Sulpicius Gallus was short and almost parallel to the shoreline. 

Note: Linné at top of Dorsa von Cotta appeared as a white circular fuzz; could not see the crater.
