Early-bird skywatchers graced with clear weather tomorrow morning (March 31) will get a celestial treat before sunrise, when Venus and the moon appear together in the east-southeast sky. 

Venus will be low onthe horizon,a brilliant “morning star,” with a lovely waning crescent moon hovering less than 5 degrees (about half the width of a human fist) above the planet and to its left. The moon will be just 9 percent illuminated, since it is less than three days before its new phase. [Moon Phases Explained]

While not an exceptionally close conjunction, the cosmic event should not disappoint skywatchers. Venus and the moon are the two brightest luminaries of the night sky, and the pair should make for a striking sight in the dawn twilight.

How to see Venus and the moon

Make sure there are no tall obstructions like buildings or trees, since by sunup Venus will only be about 12 degrees above the horizon. Your clenched fist held at arm’s length covers about 10 degrees of the sky, so Venus will only be a little higher than one fist above the horizon at daybreak. The moon will appear a bit above that.

Considering that we’re now back on daylight saving time, and sunrise is coming rather late again, there will no doubt will be a number of morning commuters heading out to work and school who might wonder what that “bright light” below and to the right of the slender sliver of moon is.

Then again, those who only now might notice Venus probably haven’t been paying much attention to what has been visible in the early morning skyof late. 

Dance of Venus

Venus has been putting on a dazzling show in the pre-sunrise eastern sky since November. During December and January, it soared high into the sky and was visible for nearly four hours before sunrise.

But from now through the month of April, Venus will linger low in the eastern predawn sky. The brilliant orb will rise like clockwork just over an hour before sunrise, but still can be easily identified as the brightest thing besides the moon.

Late in April, Venus will be joined by three other planets – Mercury, Mars and Jupiter.

All four planets ultimately will converge in an unusual planetary gathering that will persist through much of May.But more on that next month.
