Thank you!
It's interesting how much more emphasis is placed on the ascendant and moon compared to modern astrology. It seems like your sun sign doesn't figure in this analysis at all. Is it looked at further into the process once the temperament has been assessed?
Well the better Psychological Astrologers will do an elements analysis, in which Ascendant, Moon and Sun get extra prominence - and the element balance is a direct descendant from the four humours. The moder approach includes all the planets though, including the outers, whereas the traditional approach considers only the key places - Ascendant, Moon, Sun and their rulers, plus sometimes the Lord of the Geniture (strongest planet).
The tradition covers some 2,000 years, so you will not get unanimity on temperament assessment, but you will get temperament expressed using the four humours, not according to 'Sun signs'. Some writers will include the Sun's ruler - Saturn in your case (and important because it is within orb of the Ascendant) - but a lot of them do not.
You will find a more detailed coverage in Avelar and Ribeiro, towards the end of the book.
The Sun only gets further treatment in predictions - it is one of the 5 key places that determine the length of life (the others being Moon, Ascendant, Part of Fortune and Pre-natal lunation) and one of the 5 key places for profections and directions - the others being Ascendant, MC, Moon and Part of Fortune.
The Sun is lord of the heavens, so it is not treated lightly but Astrology is never, ever boiled down to the Sun alone, in the tradition (nor for that matter in good modern approaches).
You were born just after sunset, with the Moon above the horizon - so for you the Moon is far more important - not just from the temperament point of view but her role as ruler of the Ascendant gives her a particularly strong role and , she is a nocturnal planet, nocuturnally placed in a nocturnal chart (that is she is above the horizon after sunset) and placed in a nocturnal sign - a condition the Arabs called Hayz and she is waxing!
