- AS16-113-18284 and the preceding five photographs in Apollo 16's Hasselblad-magazine 113-A, show CSM Casper above craters Buisson X' and Buisson Y. Note: the photographed regions on this kind of "high-sun" Hasselblads (shadowless albedo formations) is easy to compare with Clementines photography of the moon's equator (see also: the lower left corner of LAC 65 in Ben Bussey's and Paul Spudis's Clementine Atlas of the Moon).

- AS10-33-4883, made during the mission of Apollo 10, shows an unnamed bright ray-craterlet immediately west of Buisson V. The coordinates of this bright ray-craterlet are: 0°31' South/ 110°40' East.
Discovered by Nunki .
- Overlapping images AS10-28-4023 and AS10-28-4024 show the same area as in AS10-33-4883 (the bright ray-craterlets west of Buisson V).

Buisson lies some 500 kilometres away east from the Mendeleev Basin -- a 365 kilometre-wide basin of the Nectarian period (~ 3.92 to 3.85 bn years), and about the same distance from Mare Smythii (~ 740 km, pre-Nec) in the west. The crater formed on higher ground (perhaps, on Mendeleev ejecta deposits ?) and appears well-worn where both its rim and inner region merge easily onto Buisson's relatively flat floor. The south-eastern sector of its floor is slightly higher -- is this due to material infill from influence of impact by the Nectarian-aged crater, Vesalius, nearby? If so, it may, perhaps, date the crater's age.- JohnMoore2

Description: Wikipedia


The possible bright swirl-formation southeast of Buisson Y (0.5° North/ 113.3° East)

This possible swirl was captured on the following orbital Apollo photographs:

Apollo 10:
- Orbital Hasselblad photograph AS10-28-4125.
Apollo 11:
- Orbital Hasselblad photographs AS11-36-5424 (slightly above and to the left of the frame's centre), AS11-36-5426 (near the frame's lower left corner), AS11-44-6644 (near the frame's upper left corner).
Apollo 16:
- Orbital Hasselblad photographs AS16-113-18281 (near the frame's upper left corner) and AS16-113-18282 (a little bit lower than its "near-the-corner" appearance on the preceding photograph).
Apollo 16's orbital ITEK-panoramic photographs:
- Scroll rightward at both Itek-panoramic photographs of Apollo 16's orbital stereo pair AS16-P-4279 (Forward looking) and AS16-P-4284 (Aft looking).
- Near the left margin of Apollo 16's orbital Itek-panoramic photographs AS16-P-4847 and AS16-P-4849 (both Forward looking), and also AS16-P-4854 (Aft looking).
Apollo 16's orbital FAIRCHILD-Mapping/Metric photographs:
- Frame AS16-M-0496 (near the lower left corner), and its preceding frames in REV 25.
- Frames AS16-M-0626, 0627, 0628, 0629, and 0630.
Apollo 17:
- Orbital Hasselblad photographs AS17-150-23083, 23084, 23085, 23086, and 23087 (a series of five frames).
- Orbital Hasselblad photograph AS17-150-23105 (note the bright formation's hazy appearance, on the Print Resolution JPG, 4.4 MB).
- Orbital Hasselblad photographs AS17-151-23167 and AS17-151-23170.
Apollo 17's orbital ITEK-panoramic photographs:
- AS17-P-2079 (Revolution 14, Forward looking), AS17-P-2084 (Revolution 14, Aft looking).
Important: at the following two Itek photographs it's necessary to scroll rightward toward the right margin of both frames:
- AS17-P-2497 (Revolution 28, Forward looking), AS17-P-2502 (Revolution 28, Aft looking).

Observations and questions related to the possible swirl
- Note that the bright high-albedo formation doesn't "follow" the topography of the "half"crater southeast of Buisson Y itself.
- Could this be some sort of far-side equivalent of the swirl at the near-side crater Airy?
- Is this high-albedo formation (at Buisson Y) somehow related to the nearby crescent-shaped swirl field between craters Firsov, Katchalsky, and Viviani? (the swirl field at the "centre" of the flat triangle made by Firsov, Katchalsky, and Viviani).

  • Henri Buisson (1873 – January 6, 1944) was a French physicist. In 1913 he and Charles Fabry together discovered the ozone layer.
