OBSERVING
April 2023
2 MORNING: If you're up in the wee
hours, face west to see the waxing
gibbous Moon sink toward the horizon
in tandem with Regulus, Leo's brightest
star. Less than 4° separates the pair.
6 EVENING: The nearly full Moon
rises above the east-southeastern
horizon trailing Spica, Virgo's lucida, by
less than 5°.
9-10
ALL NIGHT: Look low in the
southeast to see the waning gibbous
Moon climbing above the horizon a
smidgen more than ½° from Antares, the
Scorpion's heart. See page 46 for more
on this and other events listed here.
10, 11 EVENING: Venus is positioned
some 2½° left of the Pleiades. This
view will greet you above the westnorthwestern
horizon.
14 EVENING: Look high in the west to
see Mars less than ¼° left of Epsilon (ε)
Geminorum.
16 DAWN: Turn toward the eastsoutheast
to spot the waning crescent
Moon less than 5° below Saturn. Catch
this sight before the rising Sun burns
it away.
20 NEW MOON (4:13 AM EDT) A
hybrid solar eclipse will be visible from
small slivers of western Australia,
easternmost Indonesia, and TimorLeste.
Wider swaths will see a partial
eclipse (turn to page 48 for details).
22 DUSK: The waxing crescent Moon
hangs pleasingly in Taurus between
Venus (less than 6° upper left) and the
Pleiades (around 7° lower right). Look
toward the west-northwest to take in
this view.
22-23 ALL NIGHT: The Lyrid meteor
shower peaks. The waxing crescent
Moon sets before midnight and won't
interfere with viewing (go to page 50).
pNGC 4517 is a nearly edge-on spiral galaxy
in the constellation Virgo. The bright star
is in our own galaxy, the Milky Way, but the
superposition of the two objects makes for a
pretty picture. Read more on Virgo galaxies
on page 20. ESA / HUBBLE / NASA
sk yand tele scope .o r g * APRIL 2023 41
23 DUSK: Still in Taurus, the Moon
is now a bit more than 5° upper left of
Venus.
25 EVENING: Climbing ever higher,
the Moon, two days shy of first
quarter, gleams less than 3° right of
Mars. The pair are in Gemini, high in
the west.
27 EVENING: High in the southwest
the first-quarter Moon gleams about
4° above the Beehive Cluster (M44), in
Cancer.
29 EVENING: The Moon returns to
Leo where now, again waxing gibbous,
it sits 5° upper left of Regulus. Look
high in the south to witness this sight.
