Bright Jupiter and Saturn continue their climb into the morning sky. Jupiter is the brightest “star” in the southeast during morning twilight. Dimmer Saturn – 12.8° to the upper right of the Jovian Giant – is nearly 15° up in the southeast. In the starfield, Jupiter is passing Deneb Algiedi (δ Cap on the chart). The gap is 2.1°. Saturn is the same distance to the upper left of Theta Capricorni (θ Cap). Use a binocular to locate the dimmer starry background.
During the evening, find Mars as it approaches the Bull’s horns. The planet is about halfway up in the west as the sky darkens after sunset. It is well-above the “V” of Taurus made by Aldebaran and the Hyades star cluster.
This evening, Mars is 4.0° to the lower left of Elnath, “the one butting with horns,’ and 4.8° to the lower right of Zeta Tauri (ζ Tau on the chart).
