OBSERVING
January 2023
1 EVENING: Algol shines at minimum
brightness for roughly two hours
centered at 10:42 p.m. EST (7:42 p.m.
PST; see page 50).
3 EVENING: Look high in the eastsoutheast
to see the Moon and Mars
about 2½° apart above Aldebaran, in
Taurus, the Bull. (Turn to page 46 for
more on this and other events listed
here.)
4 EARTH is at perihelion, its closest
point to the Sun for 2023, at a distance
of 147.1 million kilometers.
4 MORNING: The short-lived
Quadrantid shower peaks (go to page
50), but the waxing gibbous Moon will
interfere with meteor-watching.
4 EVENING: Algol shines at minimum
brightness for roughly two hours
centered at 7:31 p.m. EST.
6 EVENING: The full Moon, Castor,
and Pollux form a neat triangle in
the east.
10 DAWN: Before sunup, look toward
the west to see the waning gibbous
Moon some 4° from Leo's brightest
star, Regulus.
15 DAWN: The Moon, one day past
last quarter, gleams in Virgo, around
6° left of Spica. Face south to catch
this sight.
18 DAWN: The thin, waning crescent
Moon and Antares rise together in the
southeast, about 1½° separating them.
22 DUSK: Look toward the westsouthwest
to see Venus and Saturn a
mere ½° apart. The pair sink lower as
twilight deepens, so make sure you
have a clear horizon to enjoy the view.
22 EVENING: Algol shines at
minimum brightness for roughly two
hours centered at 9:27 p.m. PST.
30 EVENING: As the month draws
to a close, the waxing gibbous Moon
visits Taurus again and sidles up to
within ½° of Mars. This time, though,
viewers will have to look high in the
southwest to take in this sight. (See
page 49 for details of the occultation.)

24 EVENING: Algol shines at
minimum brightness for roughly two
hours centered at 9:16 p.m. EST.

waxing crescent Moon hangs some 3°
below Jupiter.
28 DUSK: The first-quarter Moon
is positioned about halfway between
Mars and Jupiter high in the south,
with Venus and Saturn completing
the lineup closer to the horizon in the
west-southwest.
pThe bright reflection nebula NGC 2170, at the edge of the Monoceros R2 molecular cloud,
is at center in this wide-field image. Go to page 26 to read more on how you can observe this
