• The Big Dipper stands on its handle in the northeast around 9
p.m. In the northwest, Cassiopeia also stands on end at about
the same height. As spring approaches, the Dipper will rise higher
and Cassiopeia will move lower.

• Last-quarter Moon (exact at 2:33 p.m.). Before dawn on
Sunday the 19th, look for it in the south-southeast, as shown
here. Antares and upper Scorpius are below and to the lower
right of it, respectively. Saturn is farther to the Moon's lower left.
Sunday, February 19
• On Monday and Tuesday mornings the 20th and 21st, you'll
find Saturn glowing steadily near the waning Moon, as shown
here.
• This is the time of year when Orion stands highest in early
evening. So does Lepus the Hare under his feet! Explore the
telescopic deep-sky sights around Lepus's ears (just below Rigel)
with Sue French's Deep-Sky Wonders article,
chart and photos in the February Sky & Telescope, page 54.

• Just 8° west of the Perseus Double Cluster is an interesting binocular star cluster that wasn't even recognized as a cluster until the mid1950s, and wasn't brought to amateurs' attention until 1977 (though some of us had noticed it independently!). Today it's known as
Pazmino's Cluster, a.k.a. Stock 23.
Tuesday, February 21
• This is a fine week to look for the zodiacal light if you live in the northern latitudes, now that the evening sky is moonless and the ecliptic
tilts high upward from the west horizon at nightfall. From a clear, clean, wide-open dark site, look west at twilight's very end for a vague
but huge, tall pyramid of pearly light. It's tilted to the left, aligning along the constellations of the zodiac.
What you're seeing is sunlit interplanetary dust orbiting the Sun near the ecliptic plane. Believe it or not, seen from interstellar distances
this would be the solar system's brightest feature after the Sun itself. The "zodiacal lights" of dust around other stars may be a real obstacle
to someday seeing their small, terrestrial planets.
