Spica rises at sunset. One hour later it is 10° above the east-southeast horizon.
The star is the 14th brightest star visible in the night skies of Earth and the 10th brightest visible from mid-northern latitudes. At 250 light years, this star has an actual brightness of nearly 2,300 suns.
Spica is part of Virgo, a rather nondescript constellation that is above the star, while other stars are below the horizon during the early evening hours.
The constellation Corvus the Crow, a trapezoid shape, is to Spica’s upper right early in the evening.
Farther west, Mars is about halfway up in the sky in front of the stars of Taurus. It is nearly between Elnath and Zeta Tauri (ζ Tau on the chart), the Bull’s horns.
The Red Planet is 4.0° to the lower left of Elnath and 3.9° to the upper right of Zeta Tauri. It is below a line that connects the stars.
During the next few evenings watch the planet move between the horns.
