Mars is the lone bright planet in the evening sky.  Find it about two-thirds of the way up in the west-southwest.  It is not as bright as it was several weeks ago, although it continues its eastward march through Taurus.

Less than a week ago it passed the Pleiades star cluster.  This evening it is nicely placed to the right of the star Aldebaran (“the follower”) – the brightest star in the constellation Taurus – and the Hyades star cluster to the left of Mars, and the Pleiades cluster to the lower right of the planet.

Use a binocular to explore this region.  You can examine the Pleiades cluster and the Hyades star cluster.  Star colors abound – yellows, oranges, and blues – to indicate the stellar temperatures.

This evening Mars is 0.3° to the upper left of 37 Tauri (37 Tau on the chart), a dim star that marks the track of the sun, moon, and planets through the starfield. Use a binocular to see mars with the dimmer stars.

The planet with the neighborhood stars sets over 6 hours after sunset.
