How do you know where the Longitude of the Sun begins?
No. Did you read my post on the various orbital elements? I'll try again.Philosophaie said:Isn't the true anomaly = 0 at the vernal equinox?
Aside: Have you fixed your bug in calculating Julian date?
No!Philosophaie said:On Jan 3,2008 @6:01:20PM, the True Anomaly is aprox=0 and is at the vernal equinox.
The longitude of the sun can be calculated using the equation: longitude = (GMST + EOT + 180) % 360, where GMST is the Greenwich Mean Sidereal Time, EOT is the Equation of Time, and % is the modulo operator. These values can be found using tables or online calculators.
Finding the longitude of the sun is important for accurately tracking and predicting the position of the sun in the sky. It is also useful in determining the time of day and can aid in navigation and astronomical observations.
The Earth's tilt does not directly affect the calculation of the sun's longitude. However, it does have an indirect effect by causing the Equation of Time to vary throughout the year, which is a factor in the calculation of the sun's longitude.
Yes, the longitude of the sun can be calculated for any location on Earth. However, the accuracy of the calculation may vary depending on the location and the method used to determine the necessary values (GMST, EOT, etc).
Yes, there are various tools and resources available for calculating the longitude of the sun, such as online calculators, astronomical tables, and software programs. Additionally, many astronomical almanacs and textbooks include tables and equations for calculating the sun's longitude.
