Today is what is known as the equilux and it happens when day and night are equal and occurs a few days before the spring equinox, and a few days after the autumn equinox. What appears to be a floating leaf is actually a stray sticking to a wet car windshield in a park in Scaggsville, Maryland on September 25, 2024. Today sunrise was at 7:02am and sunset took place at 7:02pm. The green and orange colored leaf (about half for each color) seems to represent the transition from Summer to Fall. (Photo by Michael S.
