August 5 The Moon shines in the southwest as twilight fades. Look
to its right as the stars come out for Spica and, farther on,
yellower Saturn. Mars, low in the east-northeast just before the
first light of dawn, is passing less than 1 south (lower right) of
the star cluster M35 in Gemini on Saturday and Sunday mornings. Use
binoculars or a telescope. Saturday, August 6 First-quarter Moon
(exact at 7:08 a.m. EDT). The Moon is in the middle of Libra, to
the right of the stars of upper Scorpius. Sunday, August 7 The Moon
shines in the head of Scorpius this evening, near Antares. In the
southeastern sky after dusk, about a third of the way from the
horizon to overhead, are the dim but distinctive stars of the
western end of Capricornus. The scene is shown magnified at right,
roughly as if in binoculars (but brighter). Alpha Capricorni is a
wide pair, wide enough that you can probably resolve its two
components with the unaided eye if you look carefully. The Night
Sky Monday, August 8 This evening the Moon shines between the head
of Scorpius to its right and the top of the Sagittarius Teapot to
its left. The brightest asteroid, 4 Vesta, is just past opposition
this week, shining at magnitude 5.7 in Capricornus. It's an easy
find in binoculars in late evening and can be seen with the unaided
eye from a dark site once the Moon sets. Use the finder chart in
the August Sky & Telescope, page 53, or our Vesta and Ceres
finder charts online. The Dawn spacecraft is orbiting Vesta and
sending back high-res pictures. Dawn will spiral down to a much
lower orbit for closeup imaging by early Meanwhile, 1 Ceres lurks
two constellations farther east in Cetus. It's magnitude 8.3 and
brightening. After Dawn departs Vesta in summer 2012, it will fly
on to take up orbit around Ceres in February 2015. ISS Sighting
