Sun in Synastry Chart Overlays...

The sun energizes and inspires us to express ourselves. Learning to trust the power of the sun can be a challenge, but the confidence it offers is a worthwhile reward.
The magic of the sun in synastry chart overlays lies in its enormous power to give. The sun offers a gift that always shines brightly and also develops over time. Where the sun falls in a synastry chart overlay is where your partner is giving you their energy and their inspiration to grow, shine and gain confidence.

Your partner's sun will enliven you, invigorate you, and give you confidence. Most importantly, it will give you the confidence to fully express yourself, making you happier with yourself. When your partner's energy makes you happier with yourself, you are naturally attracted to this energy and also to your partner for giving it to you. For this reason, the energy and inspiration the sun brings to a synastry chart overlay can spark more romance and attraction than any other planet. If your partner's sun falls in one of the more romantic houses, such as, the first, fifth, seventh, or eighth, it is sure to breed attraction. Attraction is also likely if your mate's sun falls into a house where you are weak in your natal chart. If a house in your natal chart containing Saturn, for example, is touched by your mate's sun, the power it brings will give you help to break you free of Saturn's constraints and will make you feel better about yourself and, in turn, about your mate.
The power of the sun in the first house of a synastry chart overlay is enormous. This is one of the most beneficial positions in a synastry chart overlay because of the ego boost it offers. Your mate's sun in the first house of your synastry chart overlay can make you feel like royalty when you are with your mate. It increases your self-esteem, and makes you proud of your mate as well. For many, their mate's sun in their first house creates a desire to show off their mate as though they have won a prize. They are proud to be worthy of such a wonderful person. However, while this can be fun, it can also backfire. Not unlike Jupiter, the sun's energy can go too far. Propping up a person too far can eventually convince them that they can do better! Don't let the sun burn you. An out of control ego from either partner is a dangerous thing.

In the second, third and fourth houses, the sun is no less powerful, but it is more subtle in its influence. Your mate's sun in your second house can give you the 
energy and confidence to stake your claim in the world and build yourself a home and bank account. Because it is in a synastry chart overlay, it will likely drive you to achieve this together with your mate. In the third house, the sun livens conversation and communication, lending candor to discussions. In the third house, the sun also lends heightened energy to your every-day style, making you more active and on-the-go as a couple. A fourth-house sun in a synastry chart overlay can have a very strong pull in making you a long-term couple. There will be something deeply familiar about your mate, and although this will be felt by both of you regardless of whose sun is falling into the other's fourth house, it will be felt more powerfully by the person who is receiving the other's sun into their fourth house. Setting up house together will feel natural and because the sun represents energy, you will be driven to do this. Home activities in general will be seen as fun and invigorating when you are with your mate.
The fifth, seventh and eighth houses of the synastry chart overlay are excellent placements for the sun as far as romance and attraction. The fifth house is the natural home of the sun and it thrives here. Your partner's sun falling in you fifth house will feel like a romantic whirlwind has entered your life, full of compliments, and delightful sexual excitement. Romance will flow freely and you will see your mate as lively and fun. In the seventh house, the effect is similar. The sun in the seventh house of a synastry chart overlay is an outstanding placement for creating an invigorating, fun flirting that can last for years. Your mate's sun here will heighten their attractiveness in your eyes. The effect is deeper in the eighth as the attraction turns into intense sexual bonding for the purpose of commitment. Your mate's sun in your eighth house will create a strong need in you to share and commit fully. You will welcome and enjoy the bond that you form for the long term and it will enliven you.

In the sixth and tenth houses, the sun lends a practical assistance to work and chores in the sixth, and career in the tenth. Romance is not likely; however, over the long-term, love can build because of the help and guidance provided, especially if your sixth or tenth houses are weak in your natal chart.

The ninth and eleventh houses are not likely places for romance either, but they are wonderful for friendship. You mate's sun in either of these houses will give its energy to exploring the world outside yourself and meeting new people. It will give your relationship an unbiased and even emotional tone.

The twelfth house in a synastry chart overlay is the most subtle of places. Even the power of the sun is not enough to take away the nebulous quality of this house, but of all of the planets, the sun does the best job of it. Your mate's sun here may make you feel like they can read you better than you would like or vice versa. The sun works to break down the twelfth house secrets, but it can also lead to overconfidence here and false assumptions about unspoken topics.

Enjoy the energy of the sun wherever it lands in your synastry chart overlay. It can be truly enlivening. But always take care with it because it can burn you. Don't let it inflate your confidence unless you are truly growing with it. It will leave you stranded and alone with a false ego because you were riding on the energy of your partner's sun, not your own. The sun gives every opportunity to shine and feel glorious, but when it is your partner's sun rather than your own, it is too easily borrowed rather than developed by you. Let your partner's sun help you grow your confidence. Remember that your partner can always take it away if you borrow too much of it.
