Gregory Q, the flat-floored crater adjacent to the southwestern part of Gregory's rim, was also captured on Apollo 16's panoramic ITEK-camera frame AS16-P-5520, made during Trans Earth Coast (TEC). In this frame, Gregory Q is visible near the terminator at left, touching the frame's lower horizontal margin.
