Detailed Note: One hour before sunrise, the moon (24.6d, 24%) is over 10° above the southeast horizon. The lunar slice is 4.1° to the left of Tau Sagittarii (τ Sgr, m =3.3), at the bottom of the Teapot’s handle. At this hour Saturn is over 5° up in the east-southeast. As the sky brightens, Jupiter and Mercury follow behind. Jupiter is 9.0° to the lower left of Saturn. As twilight progresses can you see the two in the sky together without optical aid? By 30 minutes before sunrise, Jupiter is nearly 6° up in the east-southeast with Mercury 2.6° to its lower left. One hour after sunset. Mars, high in the west-southwestern sky – is well-past the Pleiades, 3.6° to the upper left of Alcyone. The planet is below a line from Alcyone to Aldebaran, 10.0° to the lower right of the constellation’s brightest star. Among the dimmer stars, use a binocular to spot 37 Tau 0.9° to the upper left of Mars.
