According to Asi Billiou, the New Moon in Libra, which will take place on 26/9, affects more Aries, Cancers, Libra and Capricorns whose Sun (their sign) is from the 0th to the 5th degree of their sign, but also those who have an ascendant or planets in these signs.
But let's look in detail at the 4 signs that will be most affected by the New Moon in Libra and in which areas they will have developments
ARIES
The New Moon in Libra opposes Jupiter in your sign and trine your ruler Mars and fills you with optimism and courage to pursue your goals and dreams. You will be full of confidence and new opportunities may come your way, either personally or professionally, especially if you were born in March. But no matter how excited you get, no matter how much you think you've hit the first lottery number, don't let your vanity and impulse control your decisions. Mercury retrograde is lurking and Jupiter in your sign is blowing your mind, so take your time and the right assurances before taking any steps. In short, whether it is a new relationship or a new partnership, do not dream because now your judgment is not working properly. This does not mean that you should reject anything, just that your binding decisions are better made after October 2 when the data will be clearer. Also, you may now have emotional disturbances and past resentments and pathologies in relationships and partnerships may surface. Because you will feel strong, you may drop your "medicine" more easily, but before you open your mouth and launch your accusations, it is good to do your self-criticism. If you decide to leave somewhere you don't have to do it in a nasty and rude way. Because we also have Mercury retrograde there will be a lot of misunderstandings and misunderstandings and if you don't keep your cool and act impulsively, as always, then you will find yourself exposed. Don't start fights, take your time and use your humor to decompress situations and don't rush, because the only thing that will save the lot is diplomacy and composure.
CANCER
The Moon rules your sign and every phase of it affects you a lot and brings out your sensitivities. The New Moon in Libra can indicate developments on the home and family front, especially if you were born in June, and will make you more emotional. The moon will put you in the process of seeking your security, dealing with home, family and relationships with your relatives and those you love and consider family. So you may decide to refresh the home space, make changes or start repairs. Others may be looking for a home and deciding to move, or dealing with your real estate and some buying and selling occurring. Also, some member of your family may need your help and you have to run to provide it or just spend more time with your people doing some enjoyable activities with them. On the other hand, you may want to have a pending discussion with your family members to set things straight if there have been any issues between you, but this is not advisable as Mercury is retrograde and misunderstandings are lurking. However, there is also the scenario of having developments and changes in your workplace and becoming stressed. But since the New Moon is in opposition to Jupiter, you may overestimate your strengths and make moves that get you into trouble. Try not to make hasty decisions and listen to the people who love you when they try to put a brake on you. Plan your new beginnings and clearings if you can after 2/10 with direct Mercury, but if they have to be done earlier don't be disappointed. Just remember that anything that starts with Mercury retrograde can be modified later.
LIBRA
The New Moon in your sign on 26/9 increases your optimism and fills you with courage to make changes in your life and find your desired balance. This process will not be easy and will be done on a very internal level, as on the day of the New Moon retrograde Mercury and your ruling planet, Venus, will be conjunct in the 12th house of your Solar chart and trine the Pluto and you may be a little caught up in your closed ones. So you will start reflecting on the past, the decisions you made and your choices and you will test everyone and everything, even yourself. Are you happy with your relationships, your work, the way others treat you, the boundaries you set and the concessions you make? Have your insecurities taken over the steering wheel of your life and are you letting others take charge? Is there anything that will make you happier? These are the things you will think about, you will worry about, and you will try to find the path you must follow so that you are well and not others. So get ready to embrace your desires and put yourself first. Don't worry about what others will think of you, focus on the things you want to achieve and let go of other people's expectations and look at your own. Just don't forget that Mercury is retrograde, so think carefully about what you want and after 2/10 when it returns to its proper course make your decisions, as then you will have a clearer judgment.
CAPRICORN
The New Moon in Libra ignites your ambitions, since it affects the 10th house in your Solar horoscope, which is about fame, power, your public image, and the issue that burns you at this time is your career and professional recognition. Are you where you want to be, enjoying your chosen job, or do you go to work and feel depressed? The moon will put you in the process of thinking about what you need to change to find your inner balance. But as much as you want to make moves and get ahead, there is something that pulls you back and pins you down. This something is yours, something internal, that works underground in your mind and won't let you rest. Maybe it's some insecurities stemming from past mistakes, maybe people and situations from the past are coming back and you don't know what to do, what to choose and how to react. You see Mercury retrograde does these. But don't be afraid. The trine of retrograde Mercury and Venus with Pluto in your sign will help you focus on the right picture and finally find what you need to change and how to transform in your life in order to lead to the success you so desire. Also, it is possible that you will accept a proposal, a professional opportunity. But there is no need for pressure and haste to make the decisions here and now. What is needed is to specify where you want to go and what your vision is carefully and methodically and if you can announce your decisions and make your new beginnings after 2/10 when Mercury gets back on track. Also, you should watch out for your tendency to be vain, because the opposition of the New Moon to Jupiter can cloud your judgment and make you take on obligations that you cannot bear or project an image that does not really express you.
