Your core self comes into focus through relationship.
Sun sextile your Sun
Twice yearly the Sun comes into sextile with its own birth degree, keeping the angle about two days before moving on, and you get a mild, friendly echo of your birthday without the fuss. Your natal Sun marks the self you keep steering toward — the thing you hope people remember you by, where your pride lives, what makes a day feel properly yours.
Pluto trine your Sun
Pluto trines your Sun through a long season, coming and going in three slow passes, and the force that usually arrives as pressure arrives instead as backing. The Sun stands for the centre of you: what you are for, what you will put your name to.
Neptune opposition your Sun
Across a long passage Neptune opposes your Sun, and your sense of self loses its sharp edges, slowly. When Neptune opposes your natal Sun in your chart, you are idealistic and compassionate to a fault, and you take on other people's problems as though they had been formally assigned to you.
Uranus trine your Sun
Uranus trines your Sun for roughly a year of on-and-off contact, usually three passes, and change comes with the door held open rather than kicked in. The Sun is your centre and your purpose; Uranus is the break from habit, the new idea, the freedom to be odd.
Saturn opposition your Sun
Saturn faces your Sun from across the chart for several months, often making three exact contacts as it goes retrograde and then direct, and the results of about fourteen years come to a head. Saturn needs roughly twenty-nine years for a full lap of the zodiac, and this opposition is the halfway point of its cycle with your Sun, fourteen or fifteen years after it last crossed it.
Jupiter sextile your Sun
For several weeks Jupiter and your Sun sit sixty degrees apart, and if Jupiter goes retrograde close to the degree the contact can repeat, making three passes in all across many months. Your Sun is what you steer by: the purpose you would put your name to.
Sun-sign horoscopes read the sky against your Sun. For the most accurate read, also read your rising sign — if you know it, that version is usually the truer story.
