Aquarian Maverick,
Your Regiomontanus chart gave the same result as Placadius. Son, I’m gonna use it. However, when you cast horary charts, you might wanna set the orbs to 50% of the astrodient’s default to fit more for horary.
SG,
According to the chart cast by the data of your question:
I got the ASC in Capricorn fittingly describing a business related question. You are Saturn Rx at 5:19 Leo in the 8th house. The 8th house placement is also very descriptive since it signifies your interest in your potential partner’s financial resources. However, you significator is suffering essential debility by being in a sign of detriment. It is, however, in its own term and face gaining some minor essential dignity. It is received by the Sun by sign and Jupiter by triplicity since this is a night chart. Saturn suffers accidental debility by being in the 8th house. It happens to be in the house co-signified by the Moon, the ruler of the 7th house (partner) in this chart.
This placement shows your interest, but there’s too much debility to ignore. Let’s wait and see.
Your partner is signified by the Moon at 5:01 in Taurus in your 4th house and her turned 10th house. Her 10th house placement shows her interest in the business/career. Your 4th house is traditionally an unfortunate house though. Her significator is on the same degree as yours casting almost perfect square to your significator. The Moon has essential dignity by being in its sign of exaltation and triplicity. It is received by Venus (natural significator of partnership) by sign and term. It is in the face of Mercury which is Rx in this chart.
Since there is an applying aspect between your significators, then the answer to you question. “will this business partnership work?” is yes. The applying aspect is a square though, suggesting some difficulties along the way. The aspect is minutes away from being perfect showing a close decision, or maybe you’ve almost already made up your mind about it.
I must warn you that her significator is much stronger than your giving her some upper hand. Maybe because she has the money. Also, her significator is in her 10th house, not 7th showing that she is generally interest in business and career, not just this particular partnership. Also, it gives her accidental dignity of being the one in charge somehow.
Mars which signifies your other friends in this chart has separated from Saturn, your significators. This may show that whatever offers of business you had from other friends are not standing anymore.
I suppose this could be a good partnership if you make the artistic calls and her the financial, You will disagree frequently, but what partners don’t?
I’ve also constructed a Frawly chart based on the time and date I got and under stood your question. The data is 4 March 2006 3:58 pm, Cairo, Egypt, GMT +2
In this chart, I got the ASC at Leo 15:26 making you the Sun at Pisces 13:51 in the 8th house. Isn’t this freakishly like the original chart? Anyway, you are interested in her financial resources. Your significator is not in detriment, but it is peregrine having no essential dignity. It is received by Jupiter (the ruler of her resources) by sign, term and face and by Mars by triplicity. It is also in the sign of exaltation of Venus. She has absolutely no problem sharing her resources with you to make this partnership work.
She is signified by Saturn Rx at 5:19 Leo in the 12th house (her turned 6th). Interestingly, her significator is in detriment this time essential (as explain before) and accidental by being in a cadent house. Her significator in the 12th house is in joy but shows that maybe you don’t know everything that she’s planning, but that doesn’t necessarily mean that she’s hiding anything related to her partnership with you. Maybe she just have parallel plans as well. Saturn being in her 6th house shows her as ready to help/co-operate. That’s good.
However, I do not see any application or translation of light between the two significator, which would show a ‘no’ answer. But before we declare that as final, let’s take a look at the Moon which is a co-significator of you and the question.
The Moon is at Taurus 16:06 in your 10th house. Again, the Moon has essential dignity by being in its sign of exaltation and triplicity. It is received by Venus (natural significator of partnership) by sign and term. It is in the face of Mercury which is Rx in this chart. The last aspect of the Moon was a square with the Sun (you!). The next aspect is an opposition with Jupiter (her resources in this chart) and final aspect of the Moon is a trine with Venus the natural ruler of partnership and the ruler of you 10th house.
This chart is quite different than the one of your original time and date, but I think we have the same result judging by the Moon. The partnership can work but there will be some disagreements (maybe about her money and how to manage it) but it has potential in the end.
Hope this helps.
A friend suggested a partnership with me where she is willing to fork out the capital to work with my business ideas and experience. I'll want to deal with fashion products. I'll be the one getting all the plans, ideas, needed things to get started while she is inexperienced in this. She fork out the capital as I do not have enough.
