New Moon Meaning
A new moon represents the end of one cycle and the beginning of another new 28 day cycle. Sun conjunct Moon gives an invigorating burst of energy and initiative. So this is an excellent time for making a fresh start, turning over a new leaf, or starting a new project. You can also question old habits, behaviors and beliefs as you search for new and inventive ways to make progress.
The effects of the December 7 new moon will last four weeks up to the Solar Eclipse on 5 January 2019. The best time for making a fresh start and for beginning new projects is during the first two weeks of this new moon cycle. This waxing phase of the Moon lasts from December 7 to the December 22 Full Moon.
New Moon December 2018 Astrology
The December 7 new moon at 15°07′ Sagittarius is square Mars and Neptune. Tempers are probably already frayed because the November 23 full moon was square Mars. I said that full moon had a nasty feel to it because of Moon square Mars by 3°40′ orb. New Moon December 2018 is square Mars by only 1°34′, so tempers are even more likely to boil over.
Mars conjunct Neptune adds a sinister, underhand influence to the aggression, sexuality and nastiness of Mars in hard aspect. On top of all this, the new moon joins a star in Hercules Constellation which acts like Mars on steroids.
Mars Conjunct Neptune
Mars conjunct Neptune is exact only 7 hours after the new moon on December 7, 2018. It is a very powerful influence on the new moon, making the testing square aspect by about 1°30′. While this conjunction can make you feel romantic and sensual, the challenging aspect to the new moon means you will more likely feel paranoid and delusional.
If you are very sensitive and scare easily then you need to take precautions. Over idealization or gullibility would leave you open to deception, scandal or slander. Keep yourself grounded in the real world as much as possible. Your good intentions to help others could easily be taken advantage of. Some people might see your generosity as a weakness, and you could even subconsciously attract spiritual vampires.
Avoid negative environments where violence, crime and drugs are prevalent. Your body could be more susceptible to poisoning and infection. Use protection if sexually active. People in general are more likely to be sexually perverse and use trickery to get in your pants.
New Moon Square Mars
New Moon square Mars can lead to tests of character from your competitors or enemies. Superiors, authorities and men in general may be looking to assert their power, leading to ego conflicts. Remember you may already be irritable and impatience because of the full moon two weeks ago that was also square Mars. So you are more likely to react to any provocation or threats with aggression, nastiness or revenge.
Not only people, but challenging events may force you to defend your goals or desires. A defensive position is best. New Moon December 2018 is likely to cause a buildup of anger, resentment or sexual frustration. Such potentially destructive energies need to be channeled constructively so they do not result in conflict, accidents, muscle pain or exhaustion.
Burning up this hot energy will also lower the risk of being subject to aggression and threats from other people who don’t handle this new moon energy so well. Exercise, hard work, sex or masturbation are preferred so long as you don’t push too hard and strain something. Working on a pet project you are passionate about is another good idea but is probably best done alone.
New Moon Square Neptune
New Moon square Neptune can have a weakening effect on your vitality and make you more susceptible to some psychological and health issues. Events or other people can cause confusion and disappointment, forcing you to battle against the odds. The December 7 new moon has the potential to make you feel insecure, guilty and apologetic. Seeing only the best in people increases the chance of becoming disillusioned or worse.
To counter the deceptive influence of this new moon you must be above-board in all of your dealings. This is not the best time for high stress competitive things like business dealings or negotiations. Predators will easily hone in on your soft side and you could be at greater risk of being taken advantage of.
Hypochondria is another issue you may have to deal with. Problems might be difficult to diagnose or there may be a misdiagnosis. You will also be more sensitive to drugs and alcohol, especially if you already have mental health issues such as paranoia or depression. Personal relationships may be subject to dishonesty and deception. Secrets will be harder to keep and harder to uncover.
New Moon in Hercules
Fixed star Ras Algethi at 16
24 is in the Head of Hercules. In hard aspect, it causes much irritation, especially in relationships with women. Ras Algethi corresponds to boldness and a drive to gain power.  So the square to Mars Neptune is likely to make people very unethical and immoral in their quest for power. Constellation Hercules is said to give strength of character, tenacity and fixity of purpose, an ardent nature and dangerous passions. 
The following celebrities have Ras Algethi in their natal charts: Arsenio Hall (AC and North Node), Bob Hawke (Sun and Mars), John Ramsey (Sun), Jennifer Carpenter (Sun), Tom Waits (Sun), Brigitte Bardot (AC), Cindy Sherman (AC), Ellen DeGeneres (AC), Angela Merkel (AC), Robert Hand (Mercury), Liz Greene (South Node), Bill Cosby (North Node) and Rudy Giuliani (Part of Fortune). The USA Horoscope (Sibly Chart) also has Ras Algethi rising.
New Moon Summary
Mars in almost exact conjunction to Neptune is the main influence on the December 7 new moon. It is a sinister influence because it is square the new moon. Major themes of new moon December 2018 will be anger, fear, deception, confusion, treachery, scandal, revenge, immorality and perversion.
Fixed star Ras Algethi joins the new moon to cause irritation from women and a ruthless drive to gain power. The keys to avoiding loss, suffering and disappointment are honesty and integrity. The actions of others are likely to make you angry, mean and vengeful. The best option would be to ignore any provocation. If you must react then do so in a straight forward, direct and honest way. Don’t leave anything to the imagination.
In particular, the new moon square Mars Neptune increases the risk of being deceived by fraudsters, charlatans, cult leaders and sexual predators. Beware of charismatic people claiming to have the answers to your problems. Sexual abuse by priests is likely to make the news yet again.
However, new moon December 2018 will stimulate your creativity and imagination. So this a good moon phase for art, music, sculpture, dance and drama. Entertainment, charity work and fighting for social causes are excellent ways to use this ethereal energy safely.
The December 2018 new moon is the last new moon in the current eclipse phase which began with the July 2018 Blood Moon Lunar Eclipse. It is a good time to look back over the last five months to check how well you have progressed with your personal goals. That lunar eclipse was at 4° Aquarius. You can look back to the August 2018 solar eclipse at 18° Leo which might apply more to your professional goals.
