Tonight Ceres is approaching the double star HD 2447.\u00a0<\/p>\n<p>The best time to catch the scene is around 9 P.M. local time, when Ceres is highest in the sky. You\u2019ll find it in the south, to the lower left of the bright planet Saturn, which dominates this region. About 9.5\u00b0 southeast of Saturn is the magnitude 3.6 star Iota (\u03b9) Ceti. From this star, move your binoculars or telescope about 2.7\u00b0 farther southeast to locate 9th-magnitude HD 2447, whose companion is about 45\u201d away. Slightly brighter 8th-magnitude Ceres is some 4.5\u2019 southeast of this pair.\u00a0 You can capture all three points of light in a single field of view.\u00a0<\/p>\n<p>Come back tomorrow night at the same time to see that Ceres has moved just northwest of\u00a0 these stars \u2014 it will sit roughly 1\u2019 from the northernmost star in the pair the night of the 16th.<\/p>\n<p><strong>Sunrise:<\/strong>\u00a06:45 A.M.<br \/><strong>Sunset:<\/strong>\u00a04:43 P.M.<br \/><strong>Moonrise:<\/strong>\u00a02:20 A.M.<br \/><strong>Moonset:<\/strong>\u00a02:23 P.M.<br \/><strong>Moon Phase:<\/strong>\u00a0Waning crescent (15%)<br \/>*Times for sunrise, sunset, moonrise, and moonset are given in local time from 40\u00b0 N 90\u00b0 W.
