The crescent moon is higher in the sky than last night. One hour after sunset, the thin moon is nearly 17° up in the west and about 7° to the lower left of the Pleiades star cluster.
Use a binocular to view earthshine on the moon. Reflected sunlight from Earth’s oceans, land masses, and clouds gently illuminate the night portion of the moon. This phase is picturesque and easily photographed with a tripod-mounted camera with an exposure that lasts a few seconds.
In addition, use the binocular to view the dozen or so stars in the Pleiades star cluster. (Large telescopes reveal a few hundred stars in the cluster.) Then turn it toward the “V” of Taurus that is made by Aldebaran and the Hyades star cluster.
Mars is higher in the sky, between the horns of Taurus, Elnath and Zeta Tauri (ζ Tau on the chart). The Red Planet is 4.4° to the upper left of Elnath and 3.6° to the upper right of Zeta Tauri.
