At 10 am EST the sun is crossing the meridian with a longitude of?
It would depend on the date, as the position of the sun crossing the meridian changes each day due to Earth's tilt. Generally, at 10 am EST, the sun's longitude when crossing the meridian would be around 30 degrees west.
How do you know sun at the meridian?
The sun is at its highest point in the sky at the meridian, which occurs at solar noon. You can determine this by observing when the sun crosses an imaginary line running from north to south in the sky. At this time, shadows will be shortest, and the sun will be directly south (or north in the Southern Hemisphere) at its maximum altitude.
What movement by the earth determines the length of one day?
One rotation by the Earth round its axis to bring the 'mean Sun' back to the meridian defines one day.The mean Sun is a Sun which comes to the meridian regularly once a day. In practice the real Sun can be fast or slow by up to 10 minutes, so the mean Sun is a fictitious sun for which those daily variations are averaged out over a year.
What is transit of Venus?
The passage of the planet Venus as it crosses in front of the sun, in opposition to the earth.
What is the name of the meridian that is located at 0 longitude?
This is called the Prime meridian, it passes through Greenwich, England.
Am and pm mean?
AM = "Ante - Meridian"PM = "Post - Meridian""Ante" and "post" mean "before" and "after"."Meridian" is the imaginary line in the sky that runs north/south and passes directly over you.In the morning, the sun moves from the eastern horizon toward the meridian. At Noon, the sun crosses the meridian. In the afternoon, the sun has crossed the meridian and moves away from it toward the west.Morning is the time before the sun crosses the meridian = Ante-Meridian = AM.Afternoon and evening is the time after the sun crosses the meridian = Post-Meridian = PM.

What is the full of a.m in 10a.m?
The full meaning of a.m. in 10 a.m. is "ante meridian," which translates to "before the meridian." It is the part of the day when the sun has not yet reached the meridian in a particular time zone.
What is the real word for AM and PM?
Ante meridian and post meridian. "Ante" is Latin for "before", "post" means after. Meridian is when the sun reaches its zenith, the highest point in its daily arc; i.e., noontime.

What is ante-meridian?
Time before noon. Before the use of standard time, (Greenwich Mean Time, time zones, etc.) most communities used solar time. Every town had its own standard of time. Noon was when the sun reached its highest point in the sky on any given day. Solar noon happens at the moment of the sun's transit of the meridian; the geographical north- south imaginary line directly overhead that the sun and other celestial bodies cross. Before the sun crosses the meridian it is morning. After the sun crosses the meridian it is afternoon (post meridian). In modern times we still use the a.m. and p.m. designations, even though they are not technically correct.
It is always the same solar time or sun time along?
a single meridian of longitude
Why are the time zones East of theprime meridian ahead of UT?
Since Earth rotates toward the east, time zones east of the prime meridian get the sun earlier in the day.
A person knows the sun time on the prime meridian and the local sun time What determination can be made?
By knowing the sun time on the prime meridian and the local sun time, one can determine their east-west position on the Earth's surface. The time difference between the two locations can be used to calculate the longitudinal difference, helping to pinpoint the exact location.
What is a zenithal passage?
A zenithal passage (also zenial passage) is the passing of the sun directly overhead scuh that no shadows are cast by a pole sticking straight up from the ground.
