14 Jun
The waxing crescent moon sets a little more than 2 hours after the sun. Low in the west at dusk, brilliant magnitude –4.0 Venus is just 2 finger-widths above or to the upper right of the moon. The Gemini Twins are 1 fist-width to the right. Use binoculars.

15 Jun
As the sky darkens this evening, look for Venus 1 fist-width to the moon’s right or lower right. The Gemini Twins, Pollux and Castor, lie just beyond Venus. Magnitude 1.3 Regulus is 1½ fist-widths to the upper left and magnitude 1.2 Mars is in a straight line 2 finger-widths beyond Regulus. Even though they are similar in brightness, Mars is easy to distinguish from Regulus because of its redness. Continuing the line beyond Mars another 2½ fist-widths brings us to magnitude 1.0 Saturn. The moon is at perigee, 57.37 earth-radii away.

16 Jun
In the west an hour after sunset, the moon is 2½ fist-widths above the horizon. Regulus is a little more than 2 finger-widths above or to the upper right, and Mars is 4 finger-widths to the upper left. With your binoculars, you should have no trouble spotting magnitude 3.9 rho Leonis, less than 1 finger-width to Mars’ left. As long as you have your binoculars out, look for a dim star one-half finger-width to the moon’s upper left. This is magnitude 4.9 pi Leonis.

On this day in 1963, Valentina Tereshkova became the first woman in space, spending 3 days in orbit aboard the Soviet spacecraft Vostok 6.

17 Jun
Mars and Regulus are about 1 fist-width to the moon’s right tonight. The star 2 fist-widths above the moon is magnitude 2.2 Denebola. Saturn is 1½ fist-widths to the moon’s upper left.

18 Jun
Tonight, Saturn is 4 finger-widths above the moon, and Mars and Regulus are a little more than 2 fist-widths to the right.

19 Jun
Saturn is 1½ fist-widths to the moon’s upper right, while Spica is 1 fist-width to the upper left this evening. The moon is at first quarter at 0430 UT.
