As was the case back in January, March 2018 has two full moons. The first one almost coincides with its rising at sunset on the March 1. The second full moon of the month, sometimes called a “Blue Moon,” occurs in morning twilight on the 31st, before its setting just after sunrise. The moon will not be unusually close this time, nor will there be an eclipse, so there won’t be much media hype about this year’s second “Blue Moon” on March 31. In March 2018, the predawn sky continues to host the three bright outer planets, all fitting within a span of 44 to 46 degrees. Starting with the full moon on March 1, follow the waning moon each morning through the 15th, and watch it pass above bright Jupiter on March 7, then skip from right to left of Mars March 9 and 10, and from right to…

In February 2018, the predawn sky hosts all three bright outer planets, spanning 44 degrees. After the total lunar eclipse at dawn on Jan. 31, follow the waning moon each morning in the first half of February, and watch it pass Jupiter on Feb. 7; Mars on Feb. 9; and Saturn on Feb. 11. Evenings offer the challenge of spotting Venus low in the western twilight glow, getting easier as its setting time improves from 24 to 56 minutes after sunset. Follow the waxing moon evenings from Feb 16, as a thin crescent near Venus, until March 1, when it’s full. Until Venus emerges from bright twilight, the evening’s most prominent point of light is Sirius, the brilliant “Dog Star,” in the southeast at dusk in February. Our morning twilight chart for February shows bright Jupiter nearly 40 degrees up in the southern sky. On Feb. 1, Mars is 12…

In January 2018, mornings are when most of the action takes place. The predawn sky hosts as many as four planets, including close pairings—Mars-Jupiter on Jan. 4-9, and Mercury-Saturn on Jan. 11-14. Also: January has two full moons! Follow the waning moon mornings in first half of month, and watch it pass the four planets—Mars-Jupiter on Jan. 11, and Mercury-Saturn on Jan. 14 and 15. Finally, don’t miss the total lunar eclipse on Jan. 31! Evenings offer no naked-eye planets, but they do offer a waxing moon Jan. 17-30, and an uncommonly large number of bright stars with the appearance of Sirius, the brilliant “Dog Star” in the east-southeast. Our New Year starts out with a “Supermoon,” the closest of 2018. As seen from Palm Springs, the full moon on Jan. 1 rises as the sun sets, at 4:49 p.m. A few minutes later, look for the huge disk of…
