Jupiter after sunset. Moon and Saturn before sunrise


Tonight for February 11, 2015

If your sky is at all clear, you can’t miss the dazzling planet Jupiter at nightfall. It’s by far the most brilliant star-like object to light up the evening sky. But to see the planet Saturn near tonight’s moon, you’ll either have to stay up late or wake up early.

From mid-northern latitudes, the slightly waning gibbous moon and the ringed planet Saturn climb over the east-southeast horizon at or after midnight. From more southerly latitudes, the moon and Saturn rise somewhat earlier. Because the exact rising times of the moon and Saturn vary by latitude and longitude, we invite you check the times in an astronomical almanac.

After rising, the moon and Saturn climb upward in the wee hours of the morning. The celestial couple soars highest in the sky shortly before dawn. In fact, the last quarter moon falls on February 3, at precisely 5:56 a.m. Pacific Standard Time (13:56 Universal Time).
