The point exactly midway along the Night portion of the sinusoidal curve is called Solar Midnight, and represents the time of day Sol is farthest below the horizon.  The simulation is paused and the scene is augmented with informative data, various small, circular, marker points, three larger, colored, touch discs, Solar and Lunar Eclipse Probe controls, and a timer, which begins at +0:00, Now.  The point exactly midway along the Day portion of the sinusoidal curve is called Solar Noon, and represents the time of day Sol is farthest above the horizon.  - Touching an Eclipse Probe control initiates a search for upcoming solar or lunar eclipses, and if one is visible from your location the You Drive simulator is temporarily reset to that date and the eclipse circumstances are displayed.  This means that if you are patient, very, very patient, you can watch Sol and Luna move! For those not so patient, touch the disclosure triangle and switch into manual You Drive mode (unavailable for the Today Extension and Screen Saver).  Of course, you must have Location Services enabled and allow Solar Coaster to access your position for accurate simulation results, and to properly detect eclipses visible at your location.  As the lengths of the Day and Night change this horizon shifts up and down the sinusoidal curve, and a trend direction triangle indicates how the shift is moving.  Touching either Sol or Luna displays a tiny bit of additional realtime information (unavailable for the Today Extension and Screen Saver).  ⁃ Touching a marker displays its time (unavailable for the Today Extension and Screen Saver).  An artificial, horizontal, horizon line is drawn such that it intersects the curve at precisely two points, Sunrise and Sunset.  - Touching the horizon line's trend direction triangle displays the amount of daylight.  Solar Coaster visualizes the rise and set of Earth's nearest star, Sol, our Sun, and probes for upcoming solar and lunar eclipses.  The App uses what astronomers call a local horizon coordinate system when displaying information, which essentially means that your current position is the center of the Universe and all calculated values are relative to you.  The timer shows the elapsed time in hours and minutes of the simulation, whether positive or negative, relative to Now.  ⁃ Touching and sliding the yellow disc animates the simulation to a random minute of the day.  ⁃ Touching the cyan disc animates the simulation through the special marker times, and those times only.  Touch the disclosure triangle once again to exit You Drive mode and resume the actual simulation.  ⁃ Touching the orange disc animates the simulation through the entire day of 1,440 minutes.  At Moonrise a smaller, secondary, sinusoidal curve appears and Luna fades-in.  This means that all points on the curve above the horizon are Day, and those below are Night.  Solar Coaster's algorithms are accurate until 2100 AD, at all longitudes, and latitudes between -81° south and +82° north.  And depending on what the time differential is and whether the simulation time is before or after Now, the tweening may be fast or slow or forward or reverse.  Solar Midnight typically does not coincide with 12 o’clock Midnight.  Solar Noon typically does not coincide with 12 o’clock Noon.  Earth's nearest celestial neighbor, Luna, our Moon, sometimes makes appearances during the visualization.  A sinusoidal curve depicts Sol’s path for a single day, Today.  Luna is drawn with its proper phase, and rotated to the precise phase angle.  Don't be surprised if you notice the visualization catch up for lost time.  The actual Sunrise and Sunset times are also displayed, in 12 or 24-hour format.  Dawn precedes Sunrise, and Dusk succeeds Sunset.  Once a minute orbital calculations are performed and the visualization is updated.
