Local Sidereal Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Local Sidereal Time = Greenwich Sidereal Time+East Longitude
LST = GST+E_long
This formula uses 3 Variables

Variables Used

Local Sidereal Time - (Measured in Radian) - Local Sidereal Time is a concept primarily used in astronomy and celestial navigation. It refers to the time measured with respect to the local meridian and the position of the stars.
Greenwich Sidereal Time - (Measured in Radian) - Greenwich Sidereal Time (GST) is a concept used in astronomy and celestial navigation to measure the rotation of the Earth relative to the stars.
East Longitude - (Measured in Radian) - East Longitude refers to a specific geographical location on the Earth's surface in relation to the prime meridian, which is designated as 0 degrees longitude.

STEP 1: Convert Input(s) to Base Unit

Greenwich Sidereal Time: 96 Degree --> 1.67551608191424 Radian (Check conversion here)
East Longitude: 15 Degree --> 0.2617993877991 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

LST = GST+E_long --> 1.67551608191424+0.2617993877991

Evaluating ... ...

LST = 1.93731546971334

STEP 3: Convert Result to Output's Unit

1.93731546971334 Radian -->111 Degree (Check conversion here)

FINAL ANSWER

111 Degree <-- Local Sidereal Time

(Calculation completed in 00.004 seconds)

What is the use of Sidereal time?

Sidereal time is used by astronomers to determine where a certain heavenly body will appear in our sky at any given time. Star positions are described in terms of declination and right ascension, and right ascension is measured in units of sidereal time.

How to Calculate Local Sidereal Time?

Local Sidereal Time calculator uses Local Sidereal Time = Greenwich Sidereal Time+East Longitude to calculate the Local Sidereal Time, Local Sidereal Time (LST) is the measure of the hour angle of the vernal equinox at a specific location, indicating the position of the Earth relative to the fixed stars, important in astronomy and celestial navigation. Local Sidereal Time is denoted by LST symbol.

How to calculate Local Sidereal Time using this online calculator? To use this online calculator for Local Sidereal Time, enter Greenwich Sidereal Time (GST) & East Longitude (E_long) and hit the calculate button. Here is how the Local Sidereal Time calculation can be explained with given input values -> 6359.832 = 1.67551608191424+0.2617993877991.

FAQ

What is Local Sidereal Time?

Local Sidereal Time (LST) is the measure of the hour angle of the vernal equinox at a specific location, indicating the position of the Earth relative to the fixed stars, important in astronomy and celestial navigation and is represented as LST = GST+E_long or Local Sidereal Time = Greenwich Sidereal Time+East Longitude. Greenwich Sidereal Time (GST) is a concept used in astronomy and celestial navigation to measure the rotation of the Earth relative to the stars & East Longitude refers to a specific geographical location on the Earth's surface in relation to the prime meridian, which is designated as 0 degrees longitude.

How to calculate Local Sidereal Time?
