Promotorium Laplace: 1978 Apr 20 UT19:30-22:35 Peter Foley
observed a tiny yellow-brown region close the tip of the cape,
north east of the precipitous west edge, in the face of the
north facing slope. The area concerned was diffuse and varied
in density despite the surroundings not varying. Foley notcied
no colour elsewhere on the Moon, though Amery thought that he
saw some in Aristarchus, but Foley thinks this was spurious.

using a x2 yellow filter, noticed that the central craterlet
detectabilty changed such that sometimes it was visible and sometimes
not. Foley (Kent, UK)noticed that the central craterlet could only just
be seen between June 2 to June 5 and was much less discernable than
during the previous lunation. No CED brightness measurements made. The

observations and confirm that the strength of the blueness is
normal.

during a lunar eclipse, the mid-eclipse shadow was so dark that details

On 1978 Aug 18 at UT 22:00 Coates (England?, UK, 3" refractor,
