SIM_sun

Picture of Sun

The Simulation

SIM_sun is a simulation of the Sun's movement across the sky. Given the location (latitude, longitude) of an observer on the Earth, the timezone (offset from UTC), and a starting local time, this simulation calculates the position of the Sun in the sky over time.

Inputs

Variable Type Units
sun_predictor.sun.observer_latitude double d
sun_predictor.sun.observer_longitude double d
sun_predictor.sun.observer_offset_from_UTC int hr
sun_predictor.sun.local_time CALENDAR_DATE --

CALENDAR_DATE

Member Type Units
year int --
month int --
day int day
hour int hour
min int min
sec double s

Outputs

Variable Type Units
sun_predictor.sun.JD double day
sun_predictor.sun.right_ascension double d
sun_predictor.sun.declination double d
sun_predictor.sun.hour_angle double d
sun_predictor.sun.local_sidereal_time double s
sun_predictor.sun.sidereal_time_at_Greenwich double s
sun_predictor.sun.solar_azimuth double d
sun_predictor.sun.solar_elevation double d
sun_predictor.sun.local_time CALENDAR_DATE --
sun_predictor.sun.utc CALENDAR_DATE --

NOTE: 0 <= Solar Azimuth < 360 degrees. North = 0, East = 90, South = 180, West = 270.
