10 May    Look to the lower left of the Big Dipper for the Gemini Twins, Pollux and Castor, in the west. Brilliant Venus is 2 fist-widths to the Twins’ lower right. You should be able to spot two bright stars to Venus’ left. Alhena is the brighter of the two. How many stars can you see between Alhena and Pollux? Now look again with binoculars.

12 May    This evening, Jupiter is high in the southwest. Regulus, in the constellation Leo, the Lion, is 1½ fist-widths to Regulus’ left. Five fist-widths beyond Regulus is Spica, in the constellation Virgo. Saturn is nearly 4 fist-widths to Spica’s lower right, near the horizon in the southeast.

13 May    To find the Little Dipper, follow the pointer stars at the end of the Big Dipper’s handle 3 fist-widths to the lower right to Polaris. Polaris is at the end of the Little Dipper’s handle. Kochab, 1½ fist-widths to Polaris’ upper right, is one of the Little Dipper’s corners. Another corner is Pherkad, 2 finger-widths to Kochab’s right or lower right. You may need binoculars to see the other stars of the dipper and handle.

15 May    The moon is at perigee, 57.39 Earth-radii (366,000 kilometers) away.

16 May    Only two days before new, the moon rises less than an hour before the sun and is no more than a thin sliver, low in the east before dawn.

7 Jan    By midnight, the moon, Jupiter and Regulus form a tight triangle in the east, with Jupiter 2 finger-widths to the moon’s upper left and Regulus 4 finger-widths to the moon’s lower left. The Big Dipper stands on its handle to the left.
