What is the process for performing a local mean time calculation accurately?
To accurately perform a local mean time calculation, you need to determine the longitude of the location, convert it to time, adjust for the equation of time, and account for any daylight saving time changes. This will give you the correct local mean time for that specific location.
How to calculate the longitude of a place when time is given?
You can calculate the longitude of a place when time is given using the Greenwich solar time.
Are there different types of solar time?
It very much depends on what is meant by solar time. Not really, it's fairly clear. There are 2 types of solar time: 1) "Apparent solar time". At any particular place this is called the "local apparent solar time", because it depends on longitude. 2) "Mean solar time". This averages out the natural variations of "apparent solar time". (The word "mean" is just a way of saying "average".) This too is depends on longitude of course, but time zones are used to cover a wide area, for convenience.
What is the relationship between apparent solar time and mean solar time?
The Earth "day" of exactly 24 hours is the "mean solar day""Mean" is basically a scientific way of saying "average". It's called a "solar day " because it's based on the position of the Sun in the sky.There are natural variations in the length of the solar day because of the Earth's elliptical orbit and axial tilt.The "mean solar day" averages out the variations that happen during the year.This makes things much more convenient for everyday life."Mean solar time" is based on the "mean solar day".The "apparent solar day" is the what we actually observe, and its length varies from day to day.A sundial measures "apparent solar time". We can convert this time to mean solar time by using something called "the equation of time".Actually, the sundial shows "local apparent solar time".That's because the time shown by a sundial depends on its exact longitude.For convenience, mean solar time has time zones (based on longitude).So, longitude also affects the relationship between these twomeasures of time.
A person knows the solar time on the prime meridian and the local solar time. what determination can be made?
Longitude
What is mean solar time called on the prime meridian?
Mean solar time on the prime meridian is known as Greenwich Mean Time (GMT).
What is solar time standard time?
the average of the mean solar time for a particular time zone
What time is solar noon time?
The same as local apparent noon. When the sun is the highest in the sky. This is true. However; to be more specific solar noon is half way between sunrise and sunset. It's at solar noon that a point gets the most direct sunlight of the day. To calculate solar noon you find out how many hours of daylight there are between sunrise and sunset and divide by 2. Add the quotient to the sunrise time and that will give you the solar noon time.
What is the mean solar time on the Prime Meridian?
greenwhich mean time
What is the relationship between Greenwich mean time and local mean time?
Greenwich Mean Time (GMT) is based on the mean solar time at the Royal Observatory in Greenwich, England. Local Mean Time (LMT) varies depending on the longitude of a specific location and is determined by dividing the Earth into 24 time zones. The relationship between GMT and LMT is that GMT serves as the standard reference point from which time zones are calculated, with each time zone typically being one hour ahead or behind GMT.
Do Albany and buffalo have the same solar noon time?
No, because of the difference between their longitudes, mean local noon at Buffalo (12:16 PM EST) is about 20½ minutes after mean local noon at Albany (11:55 AM EST).
What time of day is ther solar angle the greatest?
Local noon.
