Sun Imum Coeli in Chiang Mai

The Sun on the IC turns attention inward, toward home, roots, and the private base rather than the public record.

Does your Sun IC line reach Chiang Mai?

Three things, and the reading is yours. No account, no email, nothing kept.

Chiang Mai — the place being readChiang Mai
Still empty. Give it a day, an hour, and a town, and your lines are drawn here.

Starts at your own time zone. Change it to the one where you were born.

The town itself — choose it from the list so the place is the one you mean.

How sure are you of the hour?

From a birth certificate or a hospital record — the lines can be placed exactly.

Read here on your own device — your birth date and time never leave it. Place names you type are matched against the 5,000 towns already in the page, and only looked up by Open-Meteo when they are not among them.

How a Imum Coeli line behaves at Chiang Mai’s latitude

An underfoot line is a meridian, and it is the exact counterweight of an overhead one: the two are always 180° of longitude apart. The planet was at its lowest point at the instant you were born — beneath your feet, on the far side of the earth — and the line marking that runs pole to pole down Chiang Mai's 99.0°E. Half a world away, at 81.0°W, the same planet was standing directly overhead, and its overhead line runs down that meridian instead. The pair always arrive together. Because it is a meridian, it does not stop at a city limit: it also passes within a degree and a half of longitude of Phuket — places that may be thousands of kilometres from Chiang Mai but sit on nearly the same line of longitude.

Where Chiang Mai sits

Chiang Mai is at 18.79°N, 99.0°E in Thailandinside the tropics, where the sun passes directly overhead twice a year and the seasons are told by rain rather than by light. At the summer solstice it gets about 13 hours 8 minutes of daylight and at the winter solstice about 10 hours 52 minutes, which is the same horizon geometry a rising line is drawn from.

How close it would have to run

Distances here are measured as real ground: one degree of orb is 111 km, the same width everywhere on earth. Chiang Mai sits close enough to the equator that a degree of longitude is also about 105 km, so our figures and those of older software that measures overhead lines in longitude will agree closely.

What Sun does to a line

The ten bodies are not interchangeable. How fast one moves decides how personal its line is — and that changes how much weight this page deserves.

Speed, and what it means for you

Sun takes one year to return to the same place against the stars, and its lines shift by roughly a degree — about 111 km on the ground — every about four minutes of birth time.

💡 A line that is genuinely yours

This is one of the most personal lines in your chart. The body moves fast enough that a sibling born the same day has it somewhere quite different, so where it falls is genuinely yours rather than your generation’s.

How its lines sit on the map

The Sun never strays from the ecliptic, so it stays within 23.4° of the celestial equator and its lines reach every inhabited latitude. It moves about a degree a day against the stars, but its lines shift with the earth’s rotation — four minutes of birth time moves them roughly a hundred kilometres, the same as everything else.

Where else this meridian lands

A meridian line ignores distance. These sit within a degree and a half of Chiang Mai’s longitude, so the same Sun IC line passes close to them too:

  • Phuket Thailand, 1,215 km away

What this line is good for

The same line serves some intentions and works against others. This is computed from the archetype rather than chosen page by page, so it agrees with how the app ranks cities.

Questions about Sun IC in Chiang Mai

What does a Sun IC line mean in Chiang Mai?

The Sun on the IC turns attention inward, toward home, roots, and the private base rather than the public record. In Chiang Mai that meets the local pace and cost of living — the line itself does not change, but how loudly you feel it does.

How long is it worth staying in Chiang Mai on a Sun IC line?

Around a year or more is a gentle ceiling. Keep one outward-facing commitment on the calendar each week.

Does my Sun IC line actually reach Chiang Mai?

Only your own sky can answer that. Enter your birth details on this page and we will measure the real distance from Chiang Mai to your Sun IC line, in kilometres and in orb degrees.

Why does a Sun IC line run through a single longitude?

Because an underfoot line is a meridian. The planet was directly underfoot at one longitude at the instant you were born, and that longitude runs from pole to pole. It exists at every latitude, so it either reaches Chiang Mai at 99.0°E or it does not — latitude never rules it out.

Is a Sun IC line personal, or does everyone my age have it?

This is one of the most personal lines in your chart. The body moves fast enough that a sibling born the same day has it somewhere quite different, so where it falls is genuinely yours rather than your generation’s. Sun takes one year to go round, and its lines shift about a degree — some 111 km — every about four minutes of birth time.

Which places near Chiang Mai would this line also reach?

Nothing in the gazetteer sits within a degree of orb of Chiang Mai, so a line that misses here misses on its own. The nearest place to compare against is Bangkok, 582 km away.
