The Night Sky

摘要

Mars (magnitude -0.6 to 0.0): In Taurus. For northern hemisphere observers sunset will find Mars shining brightly high above the southeastern horizon, it will shine brightly all night and set below the west-southwest horizon about 3 1/2 hours before sunrise. For southern hemisphere observers sunset will find Mars low above the northern horizon, it will shine brightly all night and set below the west-southwest horizon about 4 1/2 hours after sunset. Mercury (magnitude 1.9 to 3.2 to 0.6): In Capricornus. For northern hemisphere observers Mercury will begin the month lost in the glare of the Sun but will rise above the east-southeastern horizon as the month progresses; at midmonth Mercury will rise above the east-southeast horizon about 1 hour before the Sun and will be found very low above the southeast horizon as the Sun rises.
