Over the line, in every year
Faces divide each sign into three bands of ten degrees. On 3 November the noon Sun runs from roughly 10.1 to 11.5 across 1930 to 2035, so even the earliest year in that span clears the boundary at ten. The answer does not depend on the year, which is not true of the day before.
It clears it by a small margin in the earliest years, a tenth of a degree or so, which is a couple of hours of solar motion. That is worth knowing if you were born in the first part of the twentieth century and near midnight, and the widget above is the way to check rather than assume. For most readers the margin is comfortable.
A solar face inside a water sign
The Chaldean order runs the seven visible planets through the thirty six faces in sequence from the fastest to the slowest, repeating. The middle face of Scorpio comes out as the Sun's. The triplicity scheme, which works by element, gives the same band to Pisces, and so to Jupiter in the older rulership or Neptune in the modern one.
Neither of those is the obvious planet for Scorpio, and that is the point of the layer. The Sun in a fixed water sign is not a combination the tradition passes over quietly. Older texts read the middle face as the part of Scorpio that is willing to be seen, less occupied with holding something back than the opening degrees are. That is interpretation, offered as interpretation, and it is the sort of detail a sign label cannot hold.
Why the degree hardly moves
A calendar year of three hundred and sixty five days is a quarter day short of the time the Sun takes to return to the same longitude. Left alone, the date on which the Sun reaches eleven degrees of Scorpio would slip a full day earlier every four years and a month earlier every century.
The leap day stops that. Three years of six hour lag are cancelled by one extra day, and the result is that the position on a fixed date rises and resets in a four year cycle instead of drifting away. The width of that cycle is what produces the range quoted here, and it is why a solar degree can be attached to a calendar date at all without naming a year.
The placements the date cannot reach
The Sun is the slowest of the personal bodies, which is why a birth date pins it and nothing else. The Moon moves through about thirteen degrees a day and will be in one of two signs on this date, with the changeover falling inside the day in a good many years.
The Ascendant is a different matter again. It is not a function of the date at all but of the local horizon at the moment of birth, so it needs a time and a place, and it turns over roughly every two hours. Anyone born on 3 November could have any of the twelve rising. Take that seriously and the sun sign stops looking like a description of a person and starts looking like what it is, one coordinate among many.
Questions people ask about this
What sign is 3 November?
Scorpio, without qualification. The sign began in the third week of October and runs to about the twenty second of November, so this date sits comfortably in the middle of it.
Which decan does 3 November fall in?
The second, running from ten to twenty degrees. The noon Sun clears the boundary at ten in every year from 1930 to 2035, though the earliest years clear it only narrowly.
Which planet rules that band?
The Sun in the Chaldean order of faces. The triplicity scheme instead assigns the band to Pisces, which points to Jupiter traditionally or Neptune in modern practice.
What degree is the Sun on this date?
Near eleven degrees of Scorpio, with noon values between roughly 10.1 and 11.5 over the modern range. The widget above gives the precise figure for your own birth.
Is a solar face unusual in Scorpio?
It is a combination the tradition remarks on, since the Sun is not associated with Scorpio in either the traditional or the modern rulership. That contrast is part of what the face is read for.
What does this birthday not settle?
The Moon within two possibilities, the Ascendant not at all, and the houses not at all. Those depend on the hour and the birthplace rather than the calendar date.
