San Francisco astrocartography

San Francisco sits at 37.77°N, 122.4°W, in the temperate middle latitudes, where the difference between a summer and a winter day is something you plan around. Which of your planetary lines fall near it, and how closely, depends entirely on when and where you were born.

In short

No planetary line belongs to San Francisco. The lines that cross it are yours, and they are different for every birth moment, two people born days apart get different readings for the same street. What is true of San Francisco for everyone is its geometry: at 37.77°N, every one of the ten bodies rises and sets here, so all forty lines can reach it.

Which of your lines reach San Francisco?

◆ A place has no fixed character

Any page telling you San Francisco is universally a “Jupiter city” is describing something that does not exist. The lines that cross it are different for every person born. The reading below is the only way to know which of yours reach here.

Do any of your lines reach San Francisco?

Three things, and the reading is yours. It runs on this device and is not kept.

What San Francisco’s position does to a reading

Astrocartography is geometry before it is anything else, so where a city sits changes how it behaves. These are facts about San Francisco rather than about you, they hold whoever is reading.

How close is close, here

Distances here are measured as real ground: one degree of orb is 111 km, the same width everywhere on earth. That matters at San Francisco, because a degree of longitude here is only about 88 km, 21% narrower. Older software that measures overhead lines in longitude will therefore report a wider figure than we do for the same city. Neither is wrong; ours describes a distance you could actually walk.

Every line can reach this latitude

A rising or setting line is a horizon curve, and it exists only where the body actually crosses the horizon. At 37.77°N that means a body within 52.2° of the celestial equator. All ten bodies stay inside that, so every one of the forty lines can pass through San Francisco’s latitude. Nothing here is ruled out by geometry, only by your own chart.

The same geometry, in daylight

The equation behind a rising line is the equation behind sunrise, so you can watch it work. At the summer solstice San Francisco gets about 14 hours 37 minutes of daylight, and at the winter solstice about 9 hours 23 minutes. The further a place sits from the equator, the steeper that swing, and the more slanted its horizon lines run.

The clock against the sun

Overhead and underfoot lines are meridians, they depend on longitude, not on what a clock happens to show. San Francisco’s clocks run 10 minutes ahead of its own sun on standard time, so the instant a planet actually crosses this meridian is not the instant local midday suggests. Any planet standing overhead here has its opposite line running down the far meridian at 57.6°E, half a world away.

Questions

About San Francisco

Which planetary lines run through San Francisco?

That depends on the day, hour, and place you were born, lines are personal, and two people born days apart can have completely different ones crossing San Francisco. Enter your birth details on this page to see which of yours pass nearby and how close they run.

Is San Francisco a good place to live?

There is no universally good or difficult city. San Francisco will hold some kinds of work and make others harder, depending on which of your lines reach it and how closely. Every line offers something and asks something in return, and we show both halves.

How close does a line have to be to San Francisco to count?

We measure the distance from the city to the line as real ground, about 111 km to the degree, the same everywhere on earth. Inside roughly half a degree is a direct hit; out to about two degrees still reads. Because a degree of longitude at San Francisco's latitude is only about 88 km, older software that measures overhead lines in longitude will quote a different figure for the same city.

Can every planetary line reach San Francisco?

Yes. At 37.77°N every one of the ten bodies rises and sets, so all forty lines can pass through this latitude. Whether any of yours actually do is a question only your own chart answers.

Where exactly is San Francisco?

San Francisco sits at 37.7749° latitude, -122.4194° longitude, keeping America/Los_Angeles time, with a population of about 873,965. Those coordinates are the point every line distance on this page is measured from.

What if none of my lines are near San Francisco?

Then we say so and leave it there. Most of the world is quiet ground for most charts, and a reading that finds something meaningful in every city on earth is not telling you anything. Quiet ground is not bad ground, it simply asks less of you.
