The week of March 4-10 takes us from Day 28 to Day 4. This week we will highlight the craters Endymion and Burckhardt, viewable on Saturday evening.
Endymion: [NE/D15; L=57°E] This is an older crater which somewhat resembles Plato [Day 8; NW/D9] in that it has a smooth, dark-chocolate floor and three-mile-high walls which cast lovely shadow spires on the flood plain below when the Sun is low. And there is an extra treat: 15 miles south-west of Endymion (about 13 arc-seconds) you might be able to spot a beautiful little concentric crater.
Burckhardt: [NE/F15] This is the crater with the “Mickey Mouse ears.” It is a remarkable exception to the rule that when one crater intrudes upon another, the younger crater (the intruder) is smaller. Burckhardt has landed smack in between two smaller but older craters, giving it the Mickey Mouse effect—so we get a double whammy!
Daylight Savings Time and Astronomers
Don’t forget that Daylight Savings begins on March 10 (never good news for astronomers!).
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]
