SKY AT A GLANCE
December 2024
4 DUSK: Face south-southwest to
take in the graceful sight of the waxing
crescent Moon about 2½° below left
of Venus. The view will become more
dramatic as twilight deepens. Turn
to page 46 for more on this and other
events listed here.
7 EVENING: The Moon, one day shy
of first quarter, hangs some 4° lower
right of Saturn in the southwest. Watch
as the pair sinks toward the westsouthwestern
horizon.
7 ALL NIGHT: Jupiter arrives at
opposition (go to page 60). This month
mighty Jove blazes in Taurus midway
between Aldebaran and Elnath, or
Beta (β) Tauri.
12 EVENING: Algol shines at minimum
brightness for roughly two hours
centered at 10:08 p.m. PST (see page 50).
13 EVENING: In the southeast, the
waxing gibbous Moon gleams a bit less
than 5° left of the Pleiades star cluster in
Taurus. Jupiter shines lower left.
13-14 ALL NIGHT: The Geminid
meteor shower is expected to peak.
However, the almost-full Moon will
severely hamper viewing.
15 EVENING: Algol shines at
minimum brightness for roughly two
hours centered at 9:58 p.m. EST
(6:58 p.m. PST).
16 EVENING: The Moon, one day
past full, forms a neat triangle with
Castor and Pollux, Gemini's bright
lights. It sits about 5° right of the stars
above the eastern horizon.
17 EVENING: Face east to see the
waning gibbous Moon perched a bit
more than 1½° above ruddy Mars.
Viewers in northern Alaska and
northernmost Canada will see the
Moon eclipse the planet.
18 EVENING: Algol shines at
minimum brightness for roughly two
hours centered at 6:47 p.m. EST.
pThe aurorae grace the skies above Nuuksio,
outside Helsinki, in southern Finland.

19 EVENING: The Moon shepherds
Regulus as they rise in the eastnortheast.
The waning gibbous is about
2° upper left of the star.
21 THE LONGEST NIGHT OF THE
YEAR in the Northern Hemisphere.
Winter begins at the solstice at
4:21 a.m. EST (1:21 a.m. PST).
24 DAWN: Look south-southeast
to see the waning crescent Moon a
bit more than 3° upper right of Spica,
Virgo's lucida. Catch this sight before
the rising Sun washes it away.
28 DAWN: A lovely sight will greet
early risers. In the southeast, a thin
lunar crescent will be just ½° right of
Antares, the Scorpion's heart, while
tiny Mercury shines a bit farther left of
the pair.
