A simulation of the rising nearly full Moon on the evening of 19 March 2011. The large Moon provides a good opportunity to become familiar with its features. On the left is the Sea of Crises, to its right is the Sea of Tranquillity where Neil Armstrong and Buzz Aldrin landed in July 1969 and the compact sea on the far right is the Sea of Moisture.
