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.

3 Jun    The waning crescent moon rises 3 hours before the sun. About 25 percent of the moon’s surface is illuminated.

4 Jun    The moon spends the next few evenings out of view, leaving us with dark skies for stargazing. In the east, Gemini is closer to the horizon. Regulus and the constellation Leo have taken over the western sky. Leo’s second brightest star, magnitude 2.2 Denebola, is 2½ fist-widths to Regulus’ upper left.

5 Jun    In the south, midway up from the horizon, two bright bodies grab our attention. The brighter is Saturn. At magnitude 0.4, it outshines magnitude 1.2 Spica, 1 fist-width to the right. Magnitude 0.2 Arcturus is high above, and magnitude 1.1 Antares is far to the lower left.

6 Jun    The Summer Triangle begins to climb in the eastern sky. Magnitude 0.1 Vega is halfway up from the horizon, a little left of east, magnitude 1.3 Deneb is 2½ fist-widths to the lower left, and 4 fist-widths to the lower right, magnitude 0.9 Altair completes the triangle. Altair rises nearly an hour after sunset, so the best view will be around midnight when the triangle is high in the east.

7 Jun    In early evening, the Big Dipper is high in the north with its handle pointing up. Find Polaris by following a line to the lower right from the pointer stars at the far end of the dipper. Polaris is the last star in the handle of the Little Dipper. Now find the brightest star of the Little Dipper, magnitude 2.2 Kochab, 1½ fist widths above or to the upper right of Polaris, depending on when you are looking.

8 Jun    New moon at 1556 UT
