21 Feb
High in the southwest this evening, the Pleiades Cluster is 2 finger-widths to the moon’s lower right, and Aldebaran is 1 fist-width to its left. Orion, the mighty hunter, lies beyond Aldebaran. The Big Dipper stands on its handle in the northern sky.

22 Feb
First-quarter moon
at 0042 UT, 1942 EST (yesterday); Capella is 2 fist-widths to the moon’s upper right tonight.

23 Feb
Look for Orion just below the moon high in the south 2 hours after sunset. From Orion’s belt, go 2 fist-widths to the lower left to magnitude -1.59 Sirius, the Dog Star.

24 Feb
The moon approaches Mars and the Gemini Twins, and the bright star 2 fist-widths below it is magnitude 0.34 Procyon.

25 Feb
About 4 hours after sunset, look south to see Mars only 2 finger-widths above the moon, the Gemini Twins 1 fist-width to its upper right, Procyon 1½ fist-widths to its lower right, and Orion far to the lower right. From the stars in Orion’s belt, a line extended 2 fist-widths to the lower left will take you to magnitude -1.6 Sirius, the Dog Star.

26 Feb
Tonight, magnitude 1.3 Regulus is 1 fist-width to the moon’s lower left and Mars is nearly 2 fist-widths to its upper right.

27 Feb
Tonight Regulus is 3 finger-widths to the upper left of the nearly full moon, which is midway between Mars 3 fist-widths to the upper right and Saturn 3 fist-widths to the lower left. The moon is at perigee, 56.10 earth-radii away. With perigee occurring only 19 hours before the full moon, we should expect high tides.
