5. The Night Sky Monday, July 29 · Last-quarter Moon (exact at 1:43 p.m. EDT). The Moon rises around midnight tonight, shining below the stars of Aries. As it climbs higher through the morning hours, look well to its lower left for the Pleiades. Tuesday, July 30 · Bright Vega shines nearly overhead these evenings, for those of us at mid-northern latitudes. Look southeast for Altair, almost as bright. Above Altair by a finger-width at arm's length is its little orange sidekick Tarazed, 3rd magnitude. Wednesday, July 31 · Find Altair again high in the southeast after dark. To its right, by about a fist and a half at arm's length, is the dim but distinctive little constellation Delphinus, the Dolphin, jumping leftward. Thursday, August 1 · The asteroid 3 Juno is brightest at opposition this week, glimmering at magnitude 9.0 at the Aquarius-Aquila border. Pick it up with your scope using the finder chart in the August Sky & Telescope, page 51.August Sky & Telescope Friday, August 2 · As summer begins to wane, The Big Dipper hangs diagonally on the wall of the northwestern sky during evening. It's about as high as bright Arcturus, shining left of it in the west.</p · In early dawn Saturday morning (you can set your alarm), the waning crescent Moon hangs to the upper right of Jupiter, Mars, and Mercury low in the east-northeast, as shown at right.
