OBSERVING November 2017 4 DAWN: Spica shines 4° right of Venus very low in the east-southeast. Bring binoculars. Faint Mars gleams some 16° above Spica. 5 DAYLIGHT-SAVING TIME ENDS at 2 a.m. for most of the U.S. and Canada. 5 - 6 NIGHT: The waxing gibbous Moon occults Aldebaran for much of North America and northern Europe; see page 51. 7 NIGHT: Algol shines at minimum brightness for roughly two hours centered at 10:56 p.m. EST; see page 51. 11 MORNING: Regulus is about 3° lower left of the just-past-last-quarter Moon as seen from North America. A few hours later the Moon occults Regulus in daytime for much of North America; see page 51. DAWN: Find Jupiter 2° below the blaze of Venus, barely above the east-southeast horizon about 45 minutes before sunrise. 16 DAWN: The very slim waning crescent Moon hangs about 6° above Jupiter and 17° below modest Mars. Brighter Venus is 3° lower left of Jupiter. 17 DAWN: The hairline Moon, one day from new, forms a loose trio with Jupiter and Venus, quite low in the east-southeast. Bring binoculars and sharp eyes. 20 DUSK: The waxing crescent Moon poses nicely to the right of Saturn before they set in the southwest. Use binoculars to hunt Mercury 7° or 8° below the pair no more than 30 minutes after sunset. 24 -25 NIGHT: Algol shines at minimum brightness for roughly two hours centered at 12:49 a.m. PST (3:49 a.m. EST). 27-28 NIGHT: Algol shines at minimum brightness for roughly two hours centered at 9:38 p.m. PST (12:38 a.m. EST). 28 DUSK: Look low in the southwest with binoculars to find Mercury and Saturn just 3° apart. Watch them close in on each other for the next 9 days. The face-on spiral galaxy NGC 7674, also known as Markarian 533, is the brightest and largest member of the Hickson 96 compact galaxy group; see page 34.
