° Solar Longitude [Sun Long] and Equation of Time [EoT, in minutes] are as of Mid Day = Local Apparent Noon.
° Sunrise/Sunset Azimuth [Rise/Set Az] measured clockwise from true north with center of Sun at horizon (east = 90°, west = 270°). Moon Phase at Sunset.

Note Twilight Solar Depressions: Civil = 6° (see brightest stars, aviation end or start of night, then artificial lights for outdoor activities),
Nautical [Sea] = 12° (horizon no longer visible at sea), Astronomical [Astro] = 18° (minimal atmospheric scatter of sunlight).
