December 2018 Monthly Overview – Sidereal Monthly Horoscopes

Welcome to Sidereal Insights, every month we explore the astrology of the current planetary transits across the heavens from a western sidereal perspective.


Be sure to read for your sidereal sun and rising sign, which may be different than the sign you’re accustomed to. Sidereal astrology is different from traditional tropical astrology, so your regular sun and rising signs may not apply in a sidereal reading or forecast.

As December opens we’ve collectively entered the leading edge of our next eclipse season, coming in early 2019, and small percentage of readers will have already begun to feel the impact.


For clues as to whether that could be you, check your sidereal birth chart–using the Fagan-Bradley zodiac, or ayanamsha–for planets or points at 21 or 22 degrees of Sagittarius or the fire signs, or for planets or points at 5 or 6 degrees of Cancer or one of the waters signs.


Then, think back to the new and full moons in November, at the 7th and 23rd, respectively, and note if something significant took place which affected your life in an outsized way. Specifically, eclipses tend to bring change which is beyond our ability to control–all we can do is adapt to it.

Sun square Mars


Tempers could flare suddenly in early December, burning hot and unusually slow when Mars and the sun square off on the 2nd. We must learn to pick our battles strategically and to let go of perceived sleights.


Sun square Neptune


Neptune complicates matters on the 5th when he squares off with the sun in watery Scorpio. Disillusionment can leave us feeling angry or argumentative, or even inclined to retaliation.


Mercury stations direct


On the 6th of December Mercury returns to direct motion,  making for an unpredictable day. Give this one some space before doing anything important, as Mercury will behave erratically near this date.


He’ll be back up to speed by Christmas, leaving the shadow of his retrograde by the 24th.


New Moon in Scorpio, Mars conjunct Neptune


The new moon in Scorpio arrives on the 7th, auguring a new cycle of transformation which is structural in nature and which burns away our illusions and denial..


This is an opportunity to embark on deep dives which result in personal transformation and opportunities for emotional and psychological healing.


Some readers will also feel the impact of January’s new moon solar eclipse in Sagittarius near this date as the luminaries transit the eclipse degree, so take note of any significant events within a week either side of the new moon.


Venus sextile Saturn


Spend time enjoying traditions near the 16th, when Venus and Saturn join forces to cast a nostalgic mood over the last days of the week. We are primed to take pleasure in family heirlooms, traditions, and rituals at this time.

Sun enters Sagittarius, Mars sextile Pluto


The sun moves into Sagittarius on the 17th to stay until mid January, emphasizing a collective desire to connect with loved ones–sometimes across great distances–in celebration, observance, or in fellowship and communion.


The sun joins Saturn and Pluto already transiting Sagittarius, and Mars and Pluto shake hands in a friendly greeting that same day, Both worldly and mental explorations are energized, and offer a profoundly transformative experience.


Sun trine Uranus retrograde


Surprises are possible near the 20th, when the sun and retrograde Uranus connect in the fire signs. A sudden change of circumstances or a fortuitous turn of events could provide unexpected benefits.


Venus trine Neptune, Mercury conjunct Jupiter


The 21st could turn out to be a lovely day, with a dreamy, romantic or fantastical vibe to it. Mercury and Jupiter team up for their third and final time this year, bringing good news, plenty of conversation, and excellent travel prospects during the December holiday season.


This is an excellent weekend to take in a film or theater performance and truly enjoy yourself.

Full Moon in Gemini


The full moon in Gemini December 22nd heralds a crescendo of conversation, commerce and travel just before year’s end, as the world collectively wraps up another year.


Use these last days of December to finalize details and complete any unfinished business from 2018 so that you can make a clean, fresh start early in the coming year.


This is a great time to be thinking about what major initiation you’d like to make in early 2019, when we have the support of every planet in the solar system in direct motion all at once.


Go ahead and make your new year’s resolution, but don’t start it until after the first new moon of the year and Uranus, our final retrograde rebel, returns to direct motion on the 7th. This major new moon–a solar eclipse in fire sign Sagittarius–brings a stellium into play, and you’ll want to harness this power with intention and a plan to make the most of it.


Watch for news from the January full moon lunar eclipse in Cancer near this date, too, as the sun passes over the eclipse degree and may activate it early for some readers. To learn more about how eclipses can affect us, or for a quick refresher, check out the Eclipse Essentials video where I break it all down for you.


Mars enters Pisces, Mercury square Neptune


Mars will move into watery Pisces on the 24th, a six week long stay lasting until early February. Fiery Mars is less at home in Pisces than in other signs, but can urge us to spend time relaxing, seeking out spiritual pursuits, and escaping from the bustle and stress of the outside world.


A misunderstanding or other challenging news could make this turn out to be the kind of day you wish you’d just stayed in bed.


Venus sextile Pluto


Late in the month, Venus and Pluto team up to set the tone for year end celebrations. Holiday parties scheduled near this date can be full of sparkle and sizzle, so make your plans accordingly.

about me

My astrological explorations began in 1994 and have taken me on an amazing, decades-long journey of discovery beginning with the teachings of Sybil Leek and continuing with those of Joanna Woolfolk, Nicholas Campion, Max Heindel, Ptolemy, Susan Miller, Carol Rushman, Steven Forrest, Cyril Fagan, Robert Powell, and Dane Rudhyar, to name just a few. I began reading privately for family and close friends in 2003 and following a profoundly transformational spiritual experience opened my practice to the public through Mystick Physick in 2014.


Now more than ever I see the need in the world for the life and soul guidance that astrology can offer to those who seek to understand its sublime language. Collectively we are waking up and determined to find meaning and purpose in our daily lives. This is the gift that astrology offers us.


I’m Phaedra, astrologer and artist of Mystick Physick. I make my home in Idaho’s gorgeous Treasure Valley with my husband of 20 years, our dog Rocket and cat Jet. In my natural habitat I can usually be found meditating, continuing my ongoing astrological explorations, painting to the astrological rhythms of the solar system, or reading about the latest discoveries in the science of consciousness or astrophysics.
