Lunar Day Twenty-Six

Abstract

And now the Moon is nearly gone again - rising just a bit ahead of the Sun (Fig. 27.1).

Let us Moon walk to first the northern cusp to take a last look at crater Anaximander, which first became visible on Lunar Day Eleven just north of J. Herschel (Fig. 27.2). Depending on exactly how many hours old the terminator is at your time of viewing, you may be able to catch a glimpse of its 2,800 m high walls and the tremendous impact that collapsed them when crater Carpenter slammed into life shortly after it was born around four billion years ago. If shadow play is right, you may see Anaximander A, which is bordered by two mountains. Look for long shadows along the southwest wall - there is a good reason for them - they rise over 2,900 m above the lunar surface. That is as tall as Mount Francais - the highest peak on the Antartic Peninsula!
