Location
The bright Spica makes it easy to locate Virgo, as it can be found by following the curve of the Big Dipper to Arcturus in Boötes and continuing from there in the same curve ("follow the arc to Arcturus and speed on to Spica").
Due to the effects of precession, the First Point of Libra, (also known as the autumn equinox point) lies within the boundaries of Virgo very close to β Virginis. This is one of the two points in the sky where the celestial equator crosses the ecliptic (the other being the First Point of Aries, now in the constellation of Pisces.) This point will pass into the neighbouring constellation of Leo around the year 2440.
