Welcome, Indigo Night Sky Watchers.

This is another good week to see bright celestial lights in the early dark immediately following 'nautical twilight' – when the center of the sun's disk passes 12° below the horizon . . . nightfall.   The horizon is still faintly visible at that time, but it's dark enough to see the stars. (During 'nautical twilight' the illumination level is such that the horizon is still visible even on a moonless night allowing mariners to take reliable star sights for navigational purposes, hence the name.)

Each of these nights – as it has been for some time and will continue to do – Venus shows forth at the western horizon in its 'Evening Star' aspect for just a few minutes after sunset. The main event, however, is the appearance of the full 'Harvest' moon late in the week. Following its familiar retrograde path through the zodiac, the moon rises a bit later and more fully illuminated each evening, reaching full brightness on Friday, the 16th, when it faces the sun along the same solar radius as the earth. All the while, Saturn and Mars continue their pas de deux in Ophiuchus, where they stand above south when the full moon rises at dusk. Have a wonderful week, and keep looking up.
