During the mission of Apollo 16 in april 1972, a number of interesting oblique northward-looking Metric/Mapping Fairchild camera photographs were made of Horrocks. These photographs are: AS16-M-0835 to 0841 in Magazine REV 27, and AS16-M-1400 to 1405 in Magazine REV 37.
Horrocks was also captured on several frames made by Apollo 16's orbital panoramic ITEK-camera, such as: AS16-P-4632 and AS16-P-4639 (near the rightmost margins of both frames), and also AS16-P-5354 (near the rightmost margin).
Post-sunrise views of Horrocks were captured on Apollo 16's earlier ITEK-frames AS16-P-4588 and AS16-P-4593 (again: near the rightmost margins of both frames).
