I installed solar panels on my roof a few years ago and since then I look at the weather report and the time of sunrise and sunset pretty much every morning. I learned long a go in school that the Vernal and Autumnal equinoxes come around the 21st of March and September. I also thought that I learned that the day and night were the same length on those days. This year when the Autumnal Equinox arrived, I looked at the weather report and noticed that the day was several minutes longer than the night. The two have been approaching each other by about 5 minutes a day since then. It is now September 25th and the difference is still 2 minutes longer for daylight. My expectation is that tomorrow the night will be longer than the day. I understand that this phenomenon is related to the latitude and the Tropic of Cancer and Tropic of Capricorn delineate the furthest northward and southward excursion of the sun in the sky. In the southern hemisphere, the day has been shorter than the night but the difference has been declining since the "Summer" solstice last June when their day was its shortest. On the equinoxes, the day and night should be 12 hours everywhere. So why did that not happen on the 22nd of September and is still on the way on the 25th? I decided to use my weather app on my phone to look at other locations. I expected the phenomenon to be related to latitude but that does not appear to be the case. I am wondering if the problem may actually be bad sunrise and sunset data from the weather channel that drives my phone app. Do we have an astronomer who could explain all of this?
