The gibbous moon that is 88% illuminated shines brightly from the western sky this morning.  Stand outside to let your eyes adapt to the darkness and you’ll see your shadow from the light of this moon phase.  If you live in the northern latitudes, the snow-covered ground may reflect the moon’s shine.

If you look carefully, you’ll spot Regulus about 8° to the left of the moon.  Castor and Pollux, the Gemini Twins, are to the lower right of Regulus and the moon.  Depending on the obstructions from your observing spot, you might see Procyon above the western horizon.
