Luna-22, a second heavy orbiter, reached the Moon on June 2, 1974 and operated for more than a year. To perform photo surveying of the surface, an elliptical orbit was established, coming as close as 15 to 30 km above the Lunar surface. From June 9 to 13, it returned 10 panoramas from its optical-mechanical camera, and then returned to a higher circular orbit to perform other experiments. The thin line running along the image is from a spacecraft strut protruding into the scanline of the camera. Portions of the square-wave retrace pattern can be seen in some sections, above and below the video signal. These panoramas are reconstructed from scanned photos.
