Mons Delisle and the crater KeplerThe week of June 19-25 takes us from lunar Day 24 to the beginning of Day 2. The Moon doesn’t rise until about 2:30 AM on Monday. This week we will highlight Mons Delisle and the crater Kepler.

Mons Delisle: [NW/F-G6] The over-imaginative among us say that if you catch it in the right light this curved mountain range, located just southwest of Delisle crater, resembles a baby with an oversized head, two outstretched arms, and trailing legs. The baby is speedily crawling southward not far from a nearby unnamed mountain group to its northwest which has informally been named “the Skull.” Your creative challenge for Monday morning is to see if you can turn the above named features into a baby and a skull.

Kepler moon craterKepler: [NW/J6] Kepler is a substantial 20-mile crater with terraced walls and some disappointingly feeble hills in place of a central mountain peak. There is a peculiar straight gash just in from the east rim which forms a long straight valley. Revisit Kepler at full Moon to appreciate how its rays intertwine with those of Copernicus and Aristarchus.

OF ADDITIONAL INTEREST IN SPACE THE WEEK OF JUNE 19-25:

On Monday night starting at 10:33 EDT there will be a double shadow transit of Jupiter’s moons Io and Europa. (Sky & Tel says 10:04, but the SkySafari app shows it beginning at 10:33. To be on the safe side, start checking shortly after 10:00.)

======================

It is highly recommended that you get a copy of Sky and Telescope’s Field Map of the Moon, the very finest Moon map available for use at the telescope. It is available for $10.95 at www.skyandtelescope.com and on Amazon. All features mentioned in this blog will be keyed to the grid on the Field Map and will look like this: Plato: [NW/D9]
