EYES TO THE SKY: Attune to planetary movements, waxing moon

On Friday and Saturday, the 7th and 8th, follow a robust crescent moon from midafternoon in the southeast until it completes its arc before midnight in the southwest.

October 3 – 16, 2016

080801-ns-new-moon-02Mt. Washington — Venus, brightest of all planets, shines in evening’s pastel twilight and sets by nightfall. A young crescent moon accompanies the goddess of love tonight, October 3; delight in the pair from about 7 p.m. until 7:30 p.m., depending on your view to the west-southwest horizon. Saturn and Mars catch the eye to the left of Venus, in the southwest, as twilight deepens. On Wednesday the 5th, the waxing crescent appears at the top of Scorpius the Scorpion, arcing toward Saturn. The moon, the ringed planet, and Scorpius’ red heart star, Antares, form a crisp equilateral triangle. A summertime constellation, the Scorpion sets early in autumn, soon to disappear from northern skies. The moon appears to the left of Saturn on the 6th.

On Friday and Saturday, the 7th and 8th, follow a robust crescent from midafternoon in the southeast until it completes its arc before midnight in the southwest. On these two weekend evenings, russet planet Mars appears below Luna as the sky darkens and the moon brightens. The moon and Mars mark the constellation Sagittarius the Archer. Mars drifts further east each successive night, journeying through Sagittarius all month.

Mercury is the brightest point low in the east in early dawn all week. The blue 10° scale as about the size of your fist held at arm's length.

Sagittarius is a readily distinguishable constellation. In relatively dark skies, its stars can be seen sketching the outline of a centaur (part man, part horse) aiming a bow and arrow. It might be easiest to begin by looking to the south for a teapot pattern: handle on the left, spout on the right and lid in the center, complete with a knob on top. It is known as the Teapot asterism. An asterism is an easy-to-discern star pattern that is usually part of an official constellation. On Thursday the 6th, Mars enhances the effect of the star Kaus Borealis that represents the knob at the top of the Teapot’s cover.

All five planets that are visible without optical aid are in view at some time during the first two weeks of October. Now that we’re attuned to Venus, Saturn and Mars in the evening sky, let’s find Mercury and Jupiter in morning twilight. Mercury is about to leave the morning sky as Jupiter is entering. Arrive at a view to the eastern horizon 45 minutes before sunrise to scan for Mercury and, after the 8th, Jupiter. The two will appear in a scintillating conjunction low to the horizon on the 11th. Binoculars are recommended.

The Full Hunter’s Moon occurs at 12:23 a.m. on the 16th. A nearly full moon rises at 6:15 p.m. on the 15th and 6:53 p.m. on the 16th. The Hunter’s moon sets at 7:25 a.m. on the 16th.

EYES TO THE SKY: Planet Venus, the Evening Star, closest, brightest mid-February

At peak magnitude, seek out the goddess of love planet in a clear blue sky in the west-southwest during daylight hours, being extremely careful to keep eyes diverted from the sun.

NATURE’S TURN: Dynamic winter designs in snow, treetops

The first porcupine in a string of winter squatters and the first to enter right beside the doorstep to my home, this entitled individual even tread onto and then sidled sideways off the edge of the lowest steppingstone to my front door to reach the crawlspace.
