The calculator provides both true azimuth (based on geographic north) and magnetic azimuth (corrected for your location&#8217;s magnetic declination).<\/p>\n<h3 class=\"wp-block-heading\" id=\"h-altitude-elevation-angle\">Altitude: elevation angle<\/h3>\n<p><strong>Altitude<\/strong> (or elevation) measures how high the sun appears above the horizon &#8211; 0\u00b0 means the sun is right at the horizon line, 90\u00b0 would be directly overhead (the zenith), and negative values indicate the sun is below the horizon.<\/p>\n<p>The calculator also accounts for atmospheric refraction, which makes the sun appear slightly higher than its geometric position (especially near the horizon).<\/p>\n<h3 class=\"wp-block-heading\" id=\"h-sun-phases-and-lighting-conditions\">Sun phases and lighting conditions<\/h3>\n<p>Beyond coordinates, the calculator shows the current <strong>sun phase<\/strong> &#8211; from astronomical night (sun more than 18\u00b0 below horizon) through the <a href=\"https:\/\/dqydj.com\/twilight-calculator\/\">various twilight phases<\/a>, <a href=\"https:\/\/dqydj.com\/golden-hour-calculator\/\">golden hour<\/a>, <a href=\"https:\/\/dqydj.com\/blue-hour-calculator\/\">blue hour<\/a>, and full daylight.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-methodology-and-accuracy\">Methodology and accuracy<\/h2>\n<p>Solar position calculations use the <a href=\"https:\/\/github.com\/mourner\/suncalc\">SunCalc.js library<\/a>.<\/p>\n<p>Atmospheric refraction correction uses the <a href=\"https:\/\/ui.adsabs.harvard.edu\/abs\/1982JNav...35..255B\" target=\"_blank\" rel=\"noopener\">Bennett formula<\/a> (Journal of Navigation, 1982), adjusted for local atmospheric conditions:<\/p>\n<div class=\"wp-block-katex-display-block katex-eq\" data-katex-display=\"true\">\n<pre>R = \\frac{1.02}{\\tan(a + \\frac{10.3\u00b0}{a + 5.11\u00b0})} \\times \\frac{P}{1010} \\times \\frac{283}{273 + T}<\/pre>\n<\/div>\n<p>Where R is refraction in arcminutes, a is the apparent altitude, P is atmospheric pressure (hPa), and T is temperature (\u00b0C).<\/p>\n<p>Air mass calculation follows the <a href=\"https:\/\/opg.optica.org\/ao\/abstract.cfm?uri=ao-28-22-4735\" target=\"_blank\" rel=\"noopener\">Kasten-Young formula<\/a> (Applied Optics, 1989) with atmospheric refraction correction:<\/p>\n<div class=\"wp-block-katex-display-block katex-eq\" data-katex-display=\"true\">\n<pre>AM = \\frac{1}{\\cos(\\theta_z) + 0.50572 \\times (96.07995 - \\theta_z)^{-1.6364}}<\/pre>\n<\/div>\n<p>Where \u03b8_z is the solar zenith angle in degrees.<\/p>\n<p>Magnetic declination uses a simplified <a href=\"https:\/\/www.ngdc.noaa.gov\/geomag\/WMM\/DoDWMM.shtml\" target=\"_blank\" rel=\"noopener\">World Magnetic Model (WMM2020)<\/a> with secular variation corrections.
