15 Jun    The bright star 2½ fist-widths above the moon this morning is magnitude 0.9 Altair. The moon is at perigee, 56.77 Earth-radii (362,000 kilometers) away.

17 Jun    In the predawn sky, the moon lies between Altair, 3 fist-widths to the upper right, and magnitude 1.3 Fomalhaut, 2½ fist-widths to the lower left.

18 Jun    The moon rises a little after midnight this morning and is high in the south at first light.

19 Jun    The last-quarter moon rises well after midnight, making for good stargazing for the next few evenings. The Big Dipper is high in the northwest with its handle pointing straight up. Rotating counter-clockwise as the evening passes, it is near the northern horizon before first light tomorrow.

20 Jun    This is the perfect time to spot the Summer Triangle in the east about an hour after sunset. The triangle’s three stars—magnitudes 0.9 Altair, 1.3 Deneb and -0.1 Vega—are the brightest in the area. Start with the highest and brightest of the three, Vega. Measure a little more than 2 fist-widths to the lower left to Deneb.The last star, Altair, is nearly 4 fist-widths to Deneb’s lower right.

21 Jun    The summer solstice occurs at 1051 UT when the sun reaches its farthest point north in the sky.

16 Jun    High in the southwest at dusk, the first-quarter moon sits between Regulus, 3 fist-widths to the right or lower right, and Spica, 2 fist-widths to the left. Venus and Mercury pass close to each other during the next few evenings. Tonight Venus is 1½ finger-widths to Mercury’s lower right. On this day in 1963, Valentina Tereschkova became the first woman in space.

17 Jun    Moving closer, the moon is about 1 fist-width to Spica’s right tonight. Can you make out dim stars between the moon and Spica? You will need good binoculars to see magnitude 4.9 psi Virginis and magnitude 5.3 49 Virginis. 

18 Jun    The waxing gibbous moon is high in the south at sunset. Magnitude 1.2 Spica is 2 finger-widths to the upper right, and magnitude 0.4 Saturn is 4 finger-widths to the upper left. Low in the west, Venus is 1 finger-width to the right of Mercury. About two-thirds of the moon is illuminated.

19 Jun    Saturn is 4 finger-widths to the moon’s upper right tonight.

20 Jun    Tonight, the moon is to the right of Scorpius, the head of the Scorpion. Low in the west at dusk, Mercury is 1.9 degrees to the lower left of Venus.

21 Jun    Magnitude 1.1 Antares, the heart of the Scorpion, is 3 finger-widths to the moon’s lower right tonight. The summer solstice occurs at 0504 UT, as the sun reaches the point farthest north of the celestial equator.
