Solar noon is the time when the Sun appears to contact the local celestial meridian. This is when the Sun apparently reaches its highest point in the sky, at 12 noon apparent solar time and can be observed using a sundial. The local or clock time of solar noon depends on the longitude and date.

What direction do shadows fall in New York at solar noon?
Solar Noon is when the sun is highest in the sky, or closest to zenith, so there would be no direction of shadow, it would be under your feet. To test this yourself on Nov. 22 the solar noon in NYC will be at 11:42:15, go find out for yourself.
What causes the position of the noon sun to vary by up to 47 degrees over a year's time?
The axial tilt of the earth is 23 and a half degrees, two times this is 47 degrees. The tilt will remain constant but as the earth rotates about the sun, the sun will get higher and lower in at noon depending on the time of year. At the equinox, around March 21rst, the length of day is about the same as the length of night. the position of the earth about the sun means that the tilt is neither away or towards the sun. The tilt of 23 and a half degrees becomes apparent (for the northern hemisphere) at the summer solstice (Around June 21st), when the tilt towards the sun gives the longest day, and the highest sun at noon. Then we have another equinox around Sept 21st, where the tilt has no effect (sun is at average height). Finally, we have the Winter solstice (around Dec 21st), when the tilt of the earth is away from the sun, to cause the shortest day and the lowest sun height. So we go from 0, to +23.5, back to 0 then to -23.5, which is reflected by the suns height at mid day.
What is the local apparent noon time?
When your shadow is directly under you. However the sun will not be directly above you unless you live within the tropics. To find yours, note the exact time of sunrise and sunset. Make it the time when 1/2 the sun is visible, or there will be refraction errors. Half way between these is LAN (Local apparent noon). This works well at mid-summer and mid-winter, but for other times of the year, you can get better accuracy by recording sunrise/sunset times over a few days and extrapolating for the next day. Another way to think about this: Local noon is the moment when the sun reaches its highest point in the sky on any given day. Wherever you are, it is when an object casts the shortest possible shadow.
How many hours of sun light are there in a short day?
The answer depends upon how far north (or south) you are. During the winter solstice at the north pole (or anywhere above the arctic circle), there is no sunlight whatsoever. The further south you go, the longer the sun peeps up above the southern horizon at noon.
How many times does Venus go into the sun?
It takes Venus 224.7 days to orbit the sun. Venus orbits the sun 1.62 times in a year. Venus is the planet 2nd closest to the sun.
How did they tell time a long time ago?
By the sun. go outside face south and if the sun is on you left its 6am to noon and if the sun is on your right the time is noon to 6pm.
When does the sun go at its highest point?
It is usually highest at noon.
At noon is the sun in the north?
Well, if you are in the southern hemisphere the sun will be going across the northern sky and if you are in the northern it will go across the southern. Depending on where you are you will know if the sun is in the north sky.
What causes the position of the noon sun to vary by as much as 47 degrees over a years time?
That is related by the inclination of Earth's axis (compared to a line that is perpendicular to the Ecliptic - Earth's plane of orbit).47 degrees is twice this inclination. At noon, the Sun can go up to 23.5 degrees north and south of the central position (the position at the time of the equinoxes). For example, for an observer at the equator, at noon the Sun could go up to 23.5 degrees north or south of the zenith.
Why are shadows the shortest at 12 noon?
The shadows are shorter at noon because the sun is higher thus not casting a longer shadow put an object in the sun at noon then watch as the sun throughout the day the object will cast a longer and longer shadow as the sun starts to go down
Why is it pleasant to go for a swim at noon while it is uncomfortable to walk?
Well, sweetheart, it's simple science. At noon, the sun is high in the sky, warming up that water nicely for a refreshing swim. But when you're walking, you're out there on dry land, feeling the full force of that scorching sun beating down on you like you owe it money. So, take a dip at noon and leave the walking for the evening when the sun's not out for blood.
When was I'll Go to Bed at Noon created?
I'll Go to Bed at Noon was created in 2004.
What nicknames does Jamie Noon go by?
Jamie Noon goes by Noonie.
When it is noon in Europe why is it early in the morning in America?
The Earth has sun hit it at different times. Most countries go by around the sunrise time for morning.
What started the system of the standard time that we use today?
The railroads. When railroading started, time was based on the position of the sun: when it is directly overhead, it's "noon." Or, on a clock, 12:00. The problem with that is, what is "noon" in Chicago is not noon in Detroit or Milwaukee. This makes it hard to calculate timetables--if it takes an hour to go from Alphaville to Bravoville, you then have to work in a time correction factor. Worse: if a train leaves Alphaville going to Bravoville at noon, and a train leaves Bravoville going to Alphaville at noon, they're going to reach their destinations at different times. So, they came up with a "standard time" deal. They divided the nation into four sections, because it takes four hours for the sun to pass across the US. Then they decided noon would be when the sun got to the middle of each section. Now, if a train leaves Bravoville for Alphaville at noon and one leaves Alphaville for Bravoville at noon, they'll both reach their destinations at the same time.
