While Buzz offloads the EASEP experiments, Neil takes a pan from southeast of the LM ( 119k ), turning clockwise between images, as indicated in his checklist. Assembly by Mike Constantine.
The first assemblies done for the ALSJ used low-resolution scans. Color version assembled by Brian McInall. Monochrome version assembled by David Harland. Marv Hein produced a VR version.
The pan location is about 20 meters south east of the LM, as indicated in Figure 3-16 ( 196k re-draft by Thomas Schwagmeier) in the Apollo 11 Preliminary Science Report.
The pan frames are AS11-40- 5930 to 5941.
A clickable version by Harald Kucharek of Figure 3-15 from the Apollo 11 Preliminary Science Report shows the direction in which each shot was taken and allows access to the images.
In frame 5931, Buzz has removed the passive seismometer experiment(PSE) package from the SEQ Bay. The foreground object with the handle is the Gold Camera, designed to take close-up photos of the very top layer of the lunar soil. Note, also, the split rock at the right edge. This rock was probably ejected by a nearby impact, possibly the one that dug West Crater, and broke into two pieces when it hit. In frame 5936, the southern part of Little West Crater on the lefthand side of the image. Part of the rim of West Crater can be seen faintly just above center. We can locate the approximate azimuths of the north and South rims of West Crater from Figure 3-15 ( 196 k re-drafted by Thomas Schwagmeier ) in the Apollo 11 Preliminary Science Report and a detail from the USGS site map.
As indicated in an alternate presentation of Figure 3-15 ( 280k ), Neil took the minus-Z pan from a location about 20 meters roughly southeast of the LM. The exact location has been added to the inset at the upper right, which shows that Neil was about 55 meters due west of the south rim of Little West Crater. From the site map detail we see that, from the south rim of Little West Crater, the north rim of West Crater is about 460 meters away on an azimuth of about 92.7 degrees. With the help of a little trigonometry, this information gives an azimuth of the north rim of West Crater from Neil's location of 92.4 degrees, with the south rim azimuth being about 112.4 degrees. During the Apollo 11 EVA, the solar azimuth was 88.1 degrees, which allows us to plot the relevant azimuths on a detail from 5936. The plotted azimuth for the south rim is very close to the lefthand edge of the horizon feature that is obviously a partly shadowed portion of the rim while the plotted north rim azimuth is close to the righthand edge of what is probably a sunlit, rock-strewn portion of the rim.
