The Night Sky
Friday, 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 2012.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.
