The week of May 22-28 takes us from Day 3 to Day 9. This week we will highlight the Sulpicius Gallus rilles on the moon, viewable on Friday evening.
Sulpicius Gallus Rilles: [NE/G10-11; L=10°E] 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.

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]
