Near the line, and clear of it
The middle face of Scorpio runs from ten to twenty degrees. On 10 November the Sun sits between about 17.2 and 18.5 at noon across 1930 to 2035, so even the latest year in that span is a degree and a half short of the line.
A degree and a half is about a day and a half of solar travel, which is a comfortable margin. Two dates further on the picture changes, because the range creeps up by roughly a degree a day and eventually contains the boundary. On this date the face is a fixed answer rather than a year dependent one, which is worth stating because it will not stay that way for long.
The two faces on either side of twenty
The band this birthday falls in is given to the Sun by the Chaldean order of decans and to Pisces by the triplicity scheme. The band beyond twenty is given to Venus in the Chaldean sequence and to Cancer in the triplicity one, which changes both attributions at once.
So the line at twenty degrees is not a small adjustment. It swaps a solar and Piscean band for a Venusian and Cancerian one, and the readings that follow are correspondingly different. This is the reason a page that states only the sign is leaving out the layer that actually varies between Scorpio birthdays, and the reason knowing your degree is more useful than knowing your date.
Why the position is predictable at all
The Sun advances a little under a degree a day and returns to the same longitude every three hundred and sixty five and a quarter days or so. The quarter day is what the leap year rule exists to absorb, and it does so in a four year cycle, so the position on a fixed calendar date rises for three years and drops back on the fourth.
The consequence is a narrow repeating band rather than a slow drift, which is why a solar degree can be quoted for a date without naming a year. The same mechanism is what allows printed sign date ranges to work for most of the calendar. The band is not zero width, though. Where it sits near a face line, as it does a couple of days after this one, the year genuinely decides the answer and a range is no longer enough.
What the hour and the place still control
The Sun is settled here in every sense that matters. Everything faster is not. The Moon moves about thirteen degrees a day, so on this date it will be in one of two or three signs and may change sign partway through.
The Ascendant is the clearest case. It depends on the rotation of the Earth, so it passes through all twelve signs in a day and depends on the birthplace as well as the clock. Two people born on 10 November in the same hospital six hours apart share a Sun, a degree and a face, and differ on the rising sign, the houses and probably the Moon. The widget above takes the hour and the place and returns the position that follows from them, along with the distance to the nearest sign boundary.
Questions people ask about this
Which decan is 10 November?
The second face of Scorpio, ten to twenty degrees, in every year of the modern range. The Sun reaches only about eighteen and a half degrees at the latest, so the line at twenty is not in play.
What degree is the Sun on this date?
Around eighteen degrees of Scorpio. Noon values fall between roughly 17.2 and 18.5 across 1930 to 2035, and the widget above returns your own figure.
What changes at twenty degrees?
Both face attributions change. The Chaldean order moves from the Sun to Venus, and the triplicity scheme moves from Pisces to Cancer, so the readings on either side differ noticeably.
Is the sun sign in doubt?
No. Scorpio runs until about the twenty second of November, so this date is roughly a dozen days clear of the nearest boundary in every year.
Why does the degree stay so consistent?
Because a leap day cancels the quarter day of drift that builds up over three ordinary years, so the position on a fixed date cycles within a narrow band instead of moving steadily.
What does the date not tell me?
The Moon beyond two or three options, the Ascendant at all, and the houses at all. Those follow from the hour and the birthplace rather than from the calendar.
