On 1989 Jun 28 at UT 08:39-09:00 D. Darling (Sun Praire, WI, USA, 3" refractor, x36) discovered that at this time Mons La Hire was the brightest feature on the Moon. LaPrice was also very bright.

The ALPO/BAA weight=1.
On 1989 Jun 28 at UT 08:39--9:00 D. Darling (Sunpraire, WI, USA, 3" refractor, x36) noted that promontorium LaPlace was very bright. LaHire brigtness was 7.0 and LaPlace was 7.5.

Aristarchus 1983 Aug 03 UT 0305-0400 Observed by R,Moseley (Coventry, UK, 6" reflector, seeing II, Transparency very good). At the start of the observation, the NE wall and immediate exterior was the brightest area visible (this is normal) and seemed tinged with a faint blue/violet. At 03:45 the impression of colour was fading in the brightening sky, but by 03:55 the colour was back again with a faint violet/purple surrounding the whole formation from E clockwise to N. The observer found it difficult to decide whether it was really a colour on the Moon, or an optical illusion. ALPO/BAA weight=1.
