During latter February, the bright moon is visible in front of the stars of Taurus.  A binocular helps to identify the starry background as the moon waxes in its gibbous phase.

Aldebaran is the brightest star in the constellation.  Notice that with the check-mark shape of the Hyades, the star forms a “V” to represent the head of Taurus.  The Pleaides star cluster rides on the Bull’s back.  Zeta Tauri (ζ Tau on the chart) and Elnath represent creature’s horns.

Here’s what to look for:

  • February 19: The moon is at its First Quarter phase at 12:47 p.m. CST.  One hour after sunset, the moon, 52% illuminated, is high in the south-southwest.  It is nearly between Aldebaran, the brightest star in Taurus, and Alcyone, in the Pleiades.  The moon is below an imaginary line that extends between the stars, 7.2° to the upper right of Aldebaran and 6.6° to the lower left of Alcyone. 
  • February 20: Look for the gibbous moon (62% illuminated) high in the south-southeast at about an hour after sunset.  The lunar orb is 7.9° to the upper left of Aldebaran and 9.1° to the right of Zeta Tauri, the Southern Horn of Taurus.
  • February 21: One hour after sunset, the moon – 71% illuminated – is high in the southeastern sky.  It is 4.4° to the upper left of ζ Tau.
