The week of April 27 – May 3 takes us from Lunar Day 5 to Day 11. This week we will highlight the crater Manilius and the Sulpicius Gallus Rilles, viewable on Wednesday evening, Day 7.
Sulpicius Gallus Rilles: [NE/G10-11] These rilles, located on the south-western shore of Mare Serenitatis, are the result of Serenity lava flows that were so heavy that the basin center subsided and opened up substantial cracks around the shore line.
Manilius: [NE/H10] The crater Manilius is conspicuously located just east of Mare Vaporum. Although Manilius is only 24 miles in diameter, it is a prominent Tycho-class crater with terraces and central peaks.
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]
