Abstract
With first quarter the day before, the Moon enters its waxing gibbous phase today, which allows us to look down directly on features that straddle the prime selenographical meridian, as shown in Figure. 13.1. The western shore of Mare Serenitatis becomes visible, along with the central portion of Mare Frigoris, and the large craters along the southern section of the prime meridian. About 134 named features become visible this day.

There is still an active observatory at Maragha. The ruins of Al-Ṭūsī’s observatory is a UNESCO World Heritage site. The library of his observatory contained about 40,000 books on astrology, astronomy, and other scientific subjects.

As a young man in the 1960s, this crater was one of the first such features that I wanted to know who or what it was named for. At that time, I did not have access to any published lunar nomenclature books or even a good lunar handbook, like the Hugh Percy Wilkins and Sir Patrick Moore book The Moon. It was not until I was working on my second bachelors degree in the early 1990s, that I was able to acquire a copy of the British Astronomical Association’s 1938 memoir “Who’s Who in the Moon” and the Blagg and Müller Named Lunar Formations.

In Figure. 13.73, Harold Hill included the following typewritten “Notes on Goldschmidt and Anaxagoras: “A chart of the floor details of Goldschmidt by Goodacre appeared in the BAA Memoir Vol. 32 Pt. (1936) [Figure. 13.72] and the accompanying notes remarked on the paucity of features shown on the older maps with the exception of that by Schmidt. This fact prompted an observation by Hill on 1954 April 12 when conditions were very favourable. Two Saros cycles later (i.e. 37 years) there was an almost exact repeat of these observing factors, when the above drawing was made. Most of the interior details were confirmed as to both character and position but with additions to the earlier findings notwithstanding the smaller aperture used. The brilliant crater Anaxagoras is a prominent centre of light streaks some of which traverse the floor of Goldschmidt but these do not become apparent at so early a stage in the lighting. What appeared to be three light streaks and ‘new’ features were seen in the SW portion of Goldschmidt—two emanating and radiating from the craterlet E. of Anaxagoras A. It is more probable that they are light ridges, but confirmation of these is sought as well as the minor details at the foot of the outer glacis of Anaxagoras.”
