The portion of the moon which the projectile was nearing was the northern hemisphere, that which the selenographic
maps place below; for these maps are generally drawn after the outline given by the glasses, and we know that they reverse the objects.
charts have been constructed with a perfection which equals, if it does not even surpass, that of our terrestrial maps.
Around the time of First Quarter, as the Moon's terminator sweeps across the lunar landscape along more-or-less selenographic
longitude 0[degrees], a particularly striking clair-obscur effect can be seen: a highlighted X (located at longitude +1.1[degrees], latitude - 25.8[degrees]) created by sunlight falling on the ridges between the craters La Caille, Blanchinus, and Purbach.
The Sun's selenographic
colongitude was 60.2[degrees] and the solar altitude ranged from 10.2[degrees] at the centre of Herodotus to 12.3[degrees] at the centre of Aristarchus at 01:30 UT.
The region is near selenographic
longitude -7.9[degrees], latitude +5.9[degrees].
Indeed there is a curious combination of scientificity and esthetic idealization in such selenographic
landmarks as Lewis Morris Rutherford's gorgeous albumen prints (produced from images taken at his private observatory in New York City in the 1860s and '70s) on which he noted the latitude and longitude of the section shown, as well as the time the photograph was taken, and James H.
Using the Lunar Terminator Visualization Tool (LTVT) software package, (14) we determined the selenographic
positions of the examined dome to 10.57[degrees]S and 48.20[degrees]W.
