March comes in like a lion and goes out like a lamb. This saying is meant to refer to the improving weather in the springtime of the year. But there is also an astronomical connection. At the beginning of March, the constellation Leo the Lion makes its way into the evening sky, appearing in the east after sunset. As the month progresses, Leo appears a little higher in the sky each night, while in the west, many constellations of the late fall and early winter are sinking toward the horizon. By the end of March, one of our winter constellations makes its exit in the western sky. For the past few weeks, the sun has been steadily encroaching on this constellation, as the earth’s revolution has caused the sun to slowly slip eastwards against the background of distant stars. Now the sun is about to pass between us and the constellation Aries the Ram. March comes in with the Lion and goes out with the Ram.
