Compute the current position of the Sun for your location:

Compute the position of the Sun for a specified date:

Compute the current position of the Sun for a specified location:

Compute the position of the Sun for a specified latitude/longitude and date:

Compute the position of the Sun for a specified city and date:

Plot the equation of time by finding the difference between the Sun's right ascension at noon and the sidereal time at noon:

Determine your final location if you walk toward the Sun from sunrise to sunset at a constant speed:

Iterate the bearing in 10-minute increments to obtain a new course and destination:

Visualize the resulting path:

Find the distance between the starting and ending points:

By default, location is specified by $GeoLocation and the date is specified by the current date:

Results are in the form of a TimeSeries when a range of dates is specified:

Results are multivalued for each date specification so plotting the results using DateListPlot will result in two curves, one for azimuth and one for altitude:

Find the position of the Sun for this location and date:

This can also be computed with AstroPosition:

Calculate the next sunrise, defined as when the upper edge of the Sun's apparent disk touches the horizon:

Find the position of the center of the Sun at that time:

The altitude of the Sun corresponds to its angular radius:

Eliminating atmospheric refraction effects, the true position of the Sun is revealed to be even further below the horizon at sunrise:

Generate the analemma of the Sun:

Plot the position of the Sun for your location between sunrise and sunset for the solstices and equinox:

Generate a map of Italy with the illumination set for sunrise:

Plot the angular distance between the Sun and Moon over a month:

Plot the position of the Sun and Moon on the celestial sphere:

Examine how the Sun's position changes with varying latitude and longitude:

With SunPosition[locationspec,Interval], results for specific locations are coerced into intervals:

Attempting to plot the results of SunPosition using "Minute" granularity or larger can result in artifacts:

One workaround to such issues is to coerce the incoming date so that it has "Instant" granularity:

Choose a location and a date:

This is the sidereal time of that location at that time:

Take the right ascensions of the Sun, the Moon and the planets:

Construct text labels for them:

Plot the directions of the Sun, the Moon and the planets as viewed from the South Pole, with respect to the fixed stars:
