Radar Images of Asteroid 2005 WK4

The Night Sky Monday, August 19 Look east in early dawn for the next few mornings and spot bright Jupiter. Look lower left of Jupiter for faint Mars. Mars forms the bottom end of a curving line with similarly bright Pollux and Castor (to its upper left). Watch this line straighten out day by day as Mars speeds eastward. It becomes exactly straight on Sunday morning the 25th. Tuesday, August 20 Full Moon (exact at 9:45 p.m. Eastern Daylight Time). The Moon rises around sunset and shines in dim Aquarius after dark. Wednesday, August 21 This is the time of year when the Big Dipper scoops down during evening, as if to pick up the water that it will dump from high overhead early next spring. Look northwest. Thursday, August 22 After dark, spot Vega overhead and Arcturus in the west. A third of the way down from Vega toward Arcturus is the dim Keystone of Hercules. Two thirds of the way is the dim semicircle of Corona Borealis, the Northern Crown. Corona has only one modestly bright star, Alphecca. Friday, August 23 The Great Square of Pegasus, tipped up on one corner, hangs above the waning gibbous Moon after the Moon rises in mid-evening.
