• As seen from the mid-northern latitudes, the waxing gibbous moon and the Gemini stars Castor and Pollux shine way up high in the southern sky at nightfall and early evening. Castor and Pollux, the constellation Gemini the Twins' two brightest stars, shine to the north of tonight's moon. The even brighter star Procyon appears to the

south of the moon. Procyon is the brightest star in the constellation Canis Minor (the Lesser Dog). Once every month, the moon passes between Procyon and the Gemini stars.
• As seen from the Southern Hemisphere, the moon passes between the Gemini stars and Procyon once a month, as well. However, people living south of the equator will see the moon, Gemini stars, and Procyon in their northern evening sky. They'll see the scene "upside down," with Procyon shining above the moon, and Castor and Pollux below the moon.
• Up and down is a matter of perspective. To avoid ambiguity, we can say that Castor and Pollux lie north of the moon, and Procyon south of the moon.
• Given clear skies, everyone around the world should be able to see the moon, the Gemini stars, and Procyon tonight!
