   This light bending action, known as atmospheric refraction, means that at most mid-temperate latitudes, sunrise starts earlier and sunset ends later, making the day of an equinox a bit longer than the night. Plus, the local weather can have an effect on the amount of atmospheric refraction. Temperatures, humidity, and barometric pressure all ...

   Sep 20, 2023 · "During the approximately 12 hours the Sun is above the horizon, Earth's orbital motion continuously "moves" it eastward. By the time the Sun arrives at the sunset horizon its position has shifted by about 2 minutes east in right ascension — equal to 0.5° or one solar diameter — and ~11.5′ south in declination (for mid-latitudes).

   Does nighttime heat more than daytime?

   • What they found was that across the stations they analyzed, both minimum (that is, nighttime) and maximum (that is, daytime) temperatures had, on average, warmed. But minimum temperature had warmed by 1.4°F whereas maximum temperatures had warmed by 0.5°F. In other words, nights warmed more than days in that time range.

   What is the difference between a day and a night?

   • For that reason day and night lengths often differ by about a minute. For example, in Detroit the equilux occurs on September 25th, when the time between sunrise and sunset is only about 13 seconds shy of 12 hours. In Phoenix it occurs on the same date, but daylight is a little more than a minute longer than night.
